Przemijający atak niedokrwienny
Zapobieganie i profilaktyka
Przemijający atak niedokrwienny (TIA) to krótkotrwały epizod niedokrwienia mózgu, rdzenia kręgowego lub siatkówki, bez trwałego uszkodzenia tkanki, stanowiący istotny czynnik ryzyka udaru mózgu. Ryzyko udaru po TIA wynosi 10-20% w ciągu 90 dni, z połową przypadków w pierwszych 48 godzinach. Wczesna interwencja, najlepiej w ciągu 24-48 godzin, obejmuje natychmiastowe podanie kwasu acetylosalicylowego (160 mg nasycająco), statyn oraz leków przeciwnadciśnieniowych, co może zmniejszyć ryzyko udaru nawet o 80-90%. Leczenie przeciwpłytkowe (kwas acetylosalicylowy 80-325 mg/dobę, klopidogrel 75 mg/dobę lub połączenie ASA z dipirydamolem) jest podstawą profilaktyki wtórnej, a u pacjentów z wysokim ryzykiem zaleca się podwójną terapię ASA (81 mg/dobę) i klopidogrelem (75 mg/dobę) przez 21 dni. W przypadku TIA z migotaniem przedsionków wskazane jest leczenie przeciwzakrzepowe NOAC lub warfaryną (INR 2-3).

Definicja i znaczenie przemijającego ataku niedokrwiennego
Przemijający atak niedokrwienny (TIA, transient ischemic attack) to krótkotrwały epizod zaburzeń neurologicznych spowodowany przejściowym niedokrwieniem mózgu, rdzenia kręgowego lub siatkówki, bez powstania ostrego zawału lub trwałego uszkodzenia tkanki. Objawy TIA ustępują zazwyczaj w ciągu kilku minut do kilku godzin i nie powodują trwałych deficytów neurologicznych.12
Przemijający atak niedokrwienny, często nazywany „mini-udarem”, jest poważnym sygnałem ostrzegawczym o zwiększonym ryzyku wystąpienia pełnoobjawowego udaru mózgu. Około 10-20% pacjentów po TIA doświadczy udaru mózgu w ciągu 90 dni, przy czym połowa tych przypadków występuje w ciągu pierwszych 48 godzin od TIA.123
TIA stanowi więc szansę na wdrożenie odpowiedniej profilaktyki, która może znacząco zmniejszyć ryzyko wystąpienia pełnoobjawowego udaru mózgu w przyszłości. Badania wykazały, że właściwe postępowanie może zredukować ryzyko udaru po TIA nawet o 80-90%.12
Profilaktyka po TIA – znaczenie szybkiego działania
Szybka ocena i wdrożenie odpowiedniego leczenia po wystąpieniu przemijającego ataku niedokrwiennego ma kluczowe znaczenie w zapobieganiu późniejszemu udarowi mózgu. Ze względu na wysokie ryzyko wystąpienia udaru w krótkim czasie po TIA, zaleca się natychmiastowe rozpoczęcie terapii profilaktycznej.12
Według wytycznych klinicznych, ocenę i wdrożenie leczenia profilaktycznego należy rozpocząć jak najszybciej, optymalnie w ciągu 24-48 godzin od wystąpienia TIA. Wczesne rozpoczęcie terapii przeciwzakrzepowej prowadzi do około 80% względnej redukcji ryzyka udaru mózgu u pacjentów z TIA.12
Przy podejrzeniu TIA, pacjent powinien natychmiast otrzymać kwas acetylosalicylowy (aspirynę), statynę i lek przeciwnadciśnieniowy (jeśli nie ma przeciwwskazań), bez oczekiwania na ocenę specjalistyczną. Następnie należy przeprowadzić szczegółową diagnostykę w celu określenia etiologii TIA i dostosowania długoterminowego planu leczenia profilaktycznego.12
Farmakologiczna profilaktyka wtórna po TIA
Leczenie przeciwpłytkowe
Leczenie przeciwpłytkowe stanowi podstawę profilaktyki wtórnej u pacjentów po przemijającym ataku niedokrwiennym niezwiązanym z zatorowością sercową. Terapia ta zmniejsza ryzyko nawrotowych epizodów naczyniowych o około 25%.12
Wszyscy pacjenci z ostrym udarem niedokrwiennym lub TIA, którzy nie stosują jeszcze leku przeciwpłytkowego, powinni otrzymać jednorazową dawkę nasycającą kwasu acetylosalicylowego, co najmniej 160 mg, natychmiast po wykluczeniu krwawienia śródczaszkowego w badaniach obrazowych.1
W długoterminowej profilaktyce wtórnej udaru można stosować:
- Kwas acetylosalicylowy (80-325 mg dziennie)12
- Klopidogrel (75 mg dziennie)12
- Połączenie kwasu acetylosalicylowego i dipirydamolu o przedłużonym uwalnianiu (25mg/200 mg dwa razy dziennie)1
Wybór odpowiedniego leku zależy od indywidualnych czynników pacjenta oraz sytuacji klinicznej.12
Podwójna terapia przeciwpłytkowa
U pacjentów z ostrym przemijającym atakiem niedokrwiennym wysokiego ryzyka lub łagodnym udarem niedokrwiennym pochodzenia niezatorowo-sercowego (NIHSS 0-3), którzy nie mają wysokiego ryzyka krwawienia, zaleca się podwójną terapię przeciwpłytkową klopidogrelem (75 mg dziennie) oraz kwasem acetylosalicylowym (81 mg dziennie) przez okres 21 dni od zdarzenia, a następnie monoterapię przeciwpłytkową (kwas acetylosalicylowy lub klopidogrel).12
Podwójna terapia przeciwpłytkowa stosowana dłużej niż przez pierwsze 21 dni po TIA nie jest zalecana, chyba że istnieją szczególne wskazania (np. stent tętniczy, objawowe zwężenie tętnicy wewnątrzczaszkowej), ze względu na zwiększone ryzyko krwawienia bez wyraźnych korzyści po 21 dniach.12
W przypadku pacjentów z TIA spowodowanym objawowym zwężeniem tętnicy wewnątrzczaszkowej wynoszącym 70-99% i niskim szacowanym ryzykiem krwawienia, należy rozważyć protokół SAMMPRIS, który obejmuje podwójną terapię przeciwpłytkową (kwas acetylosalicylowy i klopidogrel) przez pierwsze 3 miesiące, a następnie zwykle monoterapię przeciwpłytkową, w połączeniu z intensywną terapią obniżającą poziom lipidów z zastosowaniem wysokich dawek statyn, leczeniem nadciśnienia i odpowiednimi modyfikacjami stylu życia.1
Leczenie przeciwzakrzepowe
Leczenie przeciwzakrzepowe jest zalecane u pacjentów z TIA związanym z migotaniem przedsionków lub innym zdefiniowanym sercowym źródłem zatorów. Doustne antykoagulanty niebędące antagonistami witaminy K (NOAC) są preferowane w stosunku do antagonistów witaminy K ze względu na niższe ryzyko poważnych krwawień i niższą śmiertelność.123
Leczenie przeciwzakrzepowe należy rozpocząć lub wznowić po TIA natychmiast po wykluczeniu krwawienia śródczaszkowego w badaniu tomografii komputerowej.1
Leczenie nadciśnienia tętniczego
Podwyższone ciśnienie krwi (powyżej 140/90 mmHg) jest najważniejszym czynnikiem ryzyka TIA i udaru, który można leczyć. Leki przeciwnadciśnieniowe zmniejszają ryzyko udaru, niezależnie od tego, czy pacjenci mają nadciśnienie.1
Po ostrej fazie udaru lub TIA, wszyscy pacjenci z ciśnieniem skurczowym ≥130 mmHg powinni być rozważeni do leczenia przeciwnadciśnieniowego. Wytyczne Rady ds. Udaru Amerykańskiego Towarzystwa Kardiologicznego zalecają intensywne leczenie przewlekłego nadciśnienia tętniczego w celu utrzymania ciśnienia skurczowego poniżej 140 mmHg, a rozkurczowego poniżej 90 mmHg.12
W większości przypadków ciśnienia krwi nie należy agresywnie obniżać natychmiast (tj. w ciągu pierwszych 24 godzin) po udarze lub TIA, chyba że ciśnienie skurczowe jest wyższe niż 220 mmHg lub ciśnienie rozkurczowe przekracza 120 mmHg.1
Inhibitory konwertazy angiotensyny (ACE) są preferowanymi lekami ze względu na ich ochronne działanie na układ naczyniowy mózgu. W badaniu PROGRESS (Perindopril Protection Against Recurrent Stroke Study) u pacjentów po udarze lub TIA terapia skojarzona składająca się z perindoprilu (inhibitora ACE) i indapamidu (diuretyku) skutkowała 43% redukcją względnego ryzyka nawrotowego udaru (4-letnia obserwacja) zarówno u pacjentów z nadciśnieniem, jak i bez.12
Leczenie zaburzeń lipidowych
O ile nie ma przeciwwskazań, wszyscy pacjenci, którzy przebyli udar niedokrwienny, powinni otrzymać statynę, niezależnie od wyjściowego stężenia cholesterolu. Statyny nie tylko obniżają poziom cholesterolu, ale mogą również zmniejszyć ryzyko nawrotowego udaru mózgu.12
Badanie SPARCL (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) wykazało, że intensywna terapia statynami jest skuteczna w zmniejszaniu ryzyka nawrotowego udaru mózgu i powinna być podawana natychmiast po TIA.1
Zaleca się dążenie do obniżenia poziomu cholesterolu LDL poniżej 1,8 mmol/l. W przypadku pacjentów wysokiego ryzyka można rozważyć zastosowanie inhibitorów PCSK9.12
Zabiegi rewaskularyzacyjne w profilaktyce TIA
Inwazyjne metody leczenia mogą być zalecane w wybranych przypadkach, w zależności od przyczyny TIA.1
Endarterektomia tętnic szyjnych
Jeśli przyczyną TIA jest znaczne zwężenie tętnicy szyjnej, lekarz może zaproponować zabieg zwany endarterektomią tętnic szyjnych. Zabieg ten polega na usunięciu złogów tłuszczowych z tętnic szyjnych przed wystąpieniem kolejnego TIA lub udaru.1
Pacjenci z TIA etiologicznie związanym z jednostronnym zwężeniem zewnątrzczaszkowej tętnicy szyjnej powodującym ponad 50% redukcję średnicy (tj. stenozę) powinni być ocenieni pod kątem możliwej rewaskularyzacji, albo poprzez endarterektomię tętnicy szyjnej, albo przez stentowanie tętnicy szyjnej.12
Endarterektomia tętnicy szyjnej jest zalecana w przypadku objawowego ciężkiego (70-99%) zwężenia tętnic szyjnych, przy czym rewaskularyzacja powinna być przeprowadzona w ciągu 2 tygodni od wystąpienia TIA.1
Poprzez udrożnienie tętnic szyjnych w przypadku ich umiarkowanego lub znacznego zwężenia, endarterektomia tętnicy szyjnej może znacząco zmniejszyć ryzyko wystąpienia udaru lub kolejnego TIA.1
Angioplastyka i stentowanie
U niektórych pacjentów można rozważyć zabieg zwany angioplastyką tętnic szyjnych i założeniem stentu. Procedura ta polega na użyciu balonopodobnego urządzenia do otwarcia zatkanej tętnicy, a następnie umieszczeniu w tętnicy małej rurki zwanej stentem, aby utrzymać ją otwartą.1
Należy jednak zauważyć, że zarówno amerykańskie (AHA/ASA), jak i europejskie (ESO) wytyczne zalecają unikanie angioplastyki i stentowania w przypadku choroby tętnic wewnątrzczaszkowych.1
Modyfikacja stylu życia w profilaktyce TIA
Oprócz farmakoterapii, istotnym elementem profilaktyki TIA i udaru mózgu jest modyfikacja stylu życia. Zdrowe nawyki życiowe mogą chronić zdrowie i obniżyć ryzyko udaru mózgu i TIA.1
Zaprzestanie palenia tytoniu
Palenie znacząco zwiększa ryzyko TIA lub udaru mózgu, ponieważ powoduje zwężenie tętnic i sprawia, że krew jest bardziej podatna na tworzenie zakrzepów. Zaprzestanie palenia może zmniejszyć ryzyko wystąpienia TIA lub udaru mózgu.12
Metaanaliza 32 badań wykazała, że ryzyko udaru u osób obu płci i w każdym wieku było o 50% wyższe u palaczy niż u osób niepalących. Dlatego lekarz rodzinny powinien podejmować zdecydowane próby, podczas każdej wizyty w poradni, wdrożenia planu rzucania palenia, szczególnie u pacjenta, który przebył TIA.1
Ograniczenie spożycia alkoholu
Nadmierne spożycie alkoholu może prowadzić do przyrostu masy ciała, wysokiego ciśnienia krwi i nieregularnego rytmu serca (migotania przedsionków), co zwiększa ryzyko wystąpienia TIA lub udaru mózgu.12
Zaleca się ograniczenie spożycia alkoholu do 2 drinków lub mniej tygodniowo dla kobiet i 15 drinków tygodniowo dla mężczyzn, z dziennymi limitami 2 drinków dla kobiet i 3 dla mężczyzn.12
Zdrowa dieta
Zaleca się zdrową, zbilansowaną dietę bogatą w owoce, warzywa, pełne ziarna, chude mięso, drób i ryby oraz produkty mleczne o obniżonej zawartości tłuszczu. Należy ograniczyć spożycie soli, cukru i tłuszczów nasyconych.12
Zaleca się ograniczenie cholesterolu i tłuszczu, zwłaszcza tłuszczu nasyconego i tłuszczu trans, w diecie, co może zmniejszyć gromadzenie się blaszek miażdżycowych w tętnicach.1
Dieta śródziemnomorska może zmniejszyć ryzyko udaru mózgu o około 40% lub więcej u osób z wysokim ryzykiem, zgodnie z artykułem z 2019 roku.1
Regularna aktywność fizyczna
Regularna aktywność fizyczna jest jednym z niewielu sposobów na obniżenie ciśnienia krwi bez leków, jeśli masz wysokie ciśnienie krwi. Pomaga również kontrolować inne czynniki ryzyka, takie jak stres, cukrzyca i wysoki poziom cholesterolu.12
Amerykańskie Towarzystwo Kardiologiczne zaleca co najmniej 150 minut tygodniowo aktywności fizycznej o umiarkowanej intensywności, składającej się z 10-minutowych (lub dłuższych) sesji 4-7 dni w tygodniu.12
Utrzymanie prawidłowej masy ciała
Nadwaga zwiększa ryzyko rozwoju wysokiego ciśnienia krwi, problemów z sercem i cukrzycy, które są czynnikami ryzyka TIA i udaru mózgu. Utrzymywanie zdrowej wagi może pomóc w redukcji tych czynników ryzyka.12
Dobrym przedziałem jest wskaźnik masy ciała (BMI) od 18,5 do 24,9. Inną miarą może być obwód talii. Dla mężczyzn obwód talii powinien wynosić 40 cali (ok. 101 cm) lub mniej. Dla kobiet wielkość talii powinna wynosić 35 cali (ok. 89 cm) lub mniej.1
Kontrola chorób współtowarzyszących w profilaktyce TIA
Jeśli zdiagnozowano u pacjenta schorzenie, które zwiększa ryzyko TIA i udarów, takie jak wysoki poziom cholesterolu, wysokie ciśnienie krwi, migotanie przedsionków lub cukrzyca, ważne jest, aby kontrolować te stany.1
Cukrzyca
Cukrzyca, niezależnie od jej związku z nadciśnieniem, zwiększa ogólne ryzyko udaru o około 25-50%. Utrzymywanie poziomu cukru we krwi w zdrowym zakresie jest ważne dla wszystkich, ale jest szczególnie istotne dla osób z cukrzycą typu 1 lub typu 2.12
Badania MICRO-HOPE (Microalbuminuria, Cardiovascular, and Renal Outcomes in HOPE) wykazały, że terapia ramiprilem zmniejsza częstość incydentów sercowo-naczyniowych i mózgowo-naczyniowych u pacjentów z cukrzycą i jednym czynnikiem ryzyka sercowego. W MICRO-HOPE incydenty udarowe zostały zmniejszone o 33%, a zgony związane z udarem zostały zmniejszone o 37%.1
Migotanie przedsionków
Migotanie przedsionków jest jednym z najsilniejszych niezależnych czynników ryzyka udaru mózgu. Wszyscy pacjenci z TIA, którzy nie mają już rozpoznanego migotania przedsionków, powinni zostać zbadani w kierunku możliwego migotania przedsionków poprzez 72-godzinne ambulatoryjne monitorowanie EKG.12
U pacjentów z migotaniem przedsionków po TIA zaleca się długoterminowe leczenie przeciwzakrzepowe warfaryną (docelowy międzynarodowy współczynnik znormalizowany [INR] 2-3) lub nowymi doustnymi antykoagulantami (NOAC). Kwas acetylosalicylowy w dawce 325 mg/dobę stosuje się u pacjentów, którzy nie mogą przyjmować doustnych antykoagulantów.1
Edukacja i świadomość w profilaktyce TIA
Edukacja na temat TIA i udaru mózgu jest kluczowym elementem profilaktyki. Zwiększona świadomość społeczna jest niezbędna, aby skierować pacjentów na oddział ratunkowy lub oddział udarowy oraz uzyskać lepsze wsparcie dla modernizacji placówek opieki zdrowotnej w celu pełnej diagnostyki i optymalnej profilaktyki udaru mózgu.1
Kampanie edukacyjne skierowane zarówno do społeczeństwa, jak i pracowników służby zdrowia, wykazały obiecujące wyniki w zwiększaniu świadomości i poprawie wskaźników rozpoznawania TIA i udaru.1
Program wsparcia dla pacjentów po TIA lub udarze mózgu wykazał pozytywny wpływ na przestrzeganie środków profilaktyki wtórnej, chociaż jego wpływ na wskaźniki nawrotów pozostaje do pełnego ustalenia.1
Ważne jest, aby nauczyć pacjentów umiejętności adaptacyjnego radzenia sobie i dokładnie wyjaśnić realne ryzyko udaru związane z TIA.1
Indywidualizacja podejścia profilaktycznego
Profilaktyka po TIA powinna być zindywidualizowana w oparciu o specyficzne czynniki ryzyka pacjenta. Specjaliści medyczni powinni współpracować z pacjentami w celu opracowania planów opieki, które uwzględniają życzenia, cele i obawy pacjenta.12
Wytyczne American Heart Association/American Stroke Association podkreślają znaczenie współpracy z pacjentami w celu opracowania planów leczenia i profilaktyki, które będą skuteczne, ale także akceptowalne dla pacjenta.1
U bardzo osłabionych pacjentów z ograniczoną oczekiwaną długością życia, niektóre elementy profilaktyki wtórnej mogą przynieść więcej szkody niż pożytku i decyzje terapeutyczne powinny być podejmowane indywidualnie.1
Kobiety w wieku przedmenopauzalnym z udarem mózgu i TIA nie powinny otrzymywać złożonych doustnych środków antykoncepcyjnych. Kobiety po menopauzie z niedokrwiennym udarem mózgu lub TIA nie powinny otrzymywać hormonalnej terapii zastępczej w celu wtórnej profilaktyki naczyniowej.12
Podsumowanie zaleceń profilaktycznych po TIA
Skuteczna profilaktyka po przemijającym ataku niedokrwiennym wymaga zintegrowanego, systematycznego podejścia, które rozpoczyna się od rozpoznania objawów i natychmiastowej oceny medycznej, a następnie kontynuowane jest poprzez wdrożenie odpowiedniego leczenia farmakologicznego, modyfikację stylu życia i regularną kontrolę medyczną.12
Kluczowe elementy profilaktyki po TIA obejmują:
- Leczenie przeciwpłytkowe lub przeciwzakrzepowe dostosowane do etiologii TIA12
- Kontrolę ciśnienia tętniczego z docelową wartością poniżej 140/90 mmHg12
- Terapię statynami w celu obniżenia poziomu cholesterolu LDL poniżej 1,8 mmol/l1
- Kontrolę cukrzycy i innych chorób metabolicznych1
- Wczesną rewaskularyzację w przypadku istotnego zwężenia tętnicy szyjnej1
- Zaprzestanie palenia i ograniczenie spożycia alkoholu12
- Zdrową dietę i regularną aktywność fizyczną12
- Utrzymanie prawidłowej masy ciała1
Badania wykazały, że takie optymalne podejście może zmniejszyć ryzyko udaru po TIA nawet o 80%. Ponieważ TIA nie jest łagodnym stanem, należy dołożyć wszelkich starań, aby szybko i skutecznie leczyć pacjentów po jego wystąpieniu, pomimo pełnego ustąpienia objawów.12

- #1 Transient ischemic attack (TIA) – Symptoms and causes – Mayo Clinichttps://www.mayoclinic.org/diseases-conditions/transient-ischemic-attack/symptoms-causes/syc-20355679
A transient ischemic attack (TIA) is a short period of symptoms similar to those of a stroke. It’s caused by a brief blockage of blood flow to the brain. A TIA usually lasts only a few minutes and doesn’t cause long-term damage. […] However, a TIA may be a warning. About 1 in 3 people who has a TIA will eventually have a stroke, with about half occurring within a year after the TIA. […] Often called a ministroke, a TIA can serve as both a warning of a future stroke and a chance to prevent it. […] If you think you’re having or have had a transient ischemic attack, get medical attention right away. TIAs most often occur hours or days before a stroke. Being evaluated quickly means healthcare professionals can pinpoint potential treatable conditions. Treating those conditions may help you prevent a stroke.
- #1 TIA (Transient Ischemic Attack): Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/14173-transient-ischemic-attack-tia-or-mini-stroke
Transient ischemic attacks (TIAs) are often incorrectly called mini-strokes, but theyre every bit as serious as a true stroke. […] A TIA is a medical emergency you shouldnt ignore. More importantly, its a chance to get treatment that can prevent a future stroke. […] A transient ischemic attack is a medical emergency just like a stroke is. […] A TIA can be the precursor to a stroke, so get medical attention right away! […] The main reason that a TIA is a medical emergency is because its often a warning that a stroke is possible or even imminent. Up to 20% of people who have a TIA have a stroke within 90 days, and half of those strokes happen within the first two days after a TIA. […] A TIA, by definition, is a temporary issue. But it indicates that a stroke which isnt temporary could happen. That means treating the condition(s) that caused the TIA can help prevent a stroke.
- #1 Stroke and Transient Ischemic Attack – Acute and Long-Term Management – Province of British Columbiahttps://www2.gov.bc.ca/gov/content/health/practitioner-professional-resources/bc-guidelines/stroke-tia
This guideline provides recommendations for the acute and long-term management of stroke and transient ischemic attack (TIA) in adults aged 19 years, in the primary care setting. This includes secondary stroke/TIA prevention and medications. […] Timely investigation and management of transient ischemic attacks significantly reduces the chance of stroke. […] Rationale for Urgency of Assessment: TIA patients are at high risk for stroke. Timely investigation and management of TIAs significantly reduces the chance of stroke. The average risk of stroke after a TIA is up to 3% in the first 2 days, 5% in the first week and up to 12% at 90 days. A patients 90 day risk can be lowered from 12% to about 2% with timely (24 hour) investigation and aggressive management. […] Preventing a second stroke is vital in patient care. Ischemic stroke is not a single disease. It can be due to number of different stroke mechanisms and each has its natural history and treatment strategy. Investigations identify the underlying cause of the ischemic stroke in an individual patient and help provide appropriate secondary prevention.
- #1 Recent advances in the management of transient ischemic attackshttps://pmc.ncbi.nlm.nih.gov/articles/PMC9340656/
Transient ischemic attack (TIA) constitutes an important clinical condition, indicating the presence of considerable risk for a subsequent ischemic stroke. Its prompt diagnosis and management have the potential for reducing the risk of neurologic disability, highlighting the critical need to prioritize the care of patients with TIA. […] The diagnosis of transient ischemic attacks (TIAs) is essential to reduce the risk of subsequent ischemic stroke; this risk can be as high as 20% in the 3 months following TIA depending on the causative mechanism of the index cerebrovascular event. Therefore, the goals for evaluation and management of patients suspected of having a TIA are to establish a clinical diagnosis with as much certainty as possible, define the etiologic mechanism of the TIA, risk-stratify the patient for possible subsequent stroke, and implement a management plan to prevent the recurrent event.
- #1 Recent advances in the management of transient ischemic attackshttps://pmc.ncbi.nlm.nih.gov/articles/PMC9340656/
The primary objective of evaluating patients with TIA is prevention of subsequent ischemic stroke, clinicians should consider that entity a medical emergency and institute a quick and efficient diagnostic evaluation. […] The degree of stroke post-TIA risk varies by patient characteristics and etiopathogenic mechanism. […] Early antithrombotic therapy leads to an about 80% relative reduction of stroke risk in patients with TIA. […] Dual antiplatelet therapy is also an important therapeutic consideration in the management of patients with TIA. […] Patients with TIA etiologically associated with an ipsilateral extracranial carotid atherosclerotic lesion causing more than 50% diameter reduction (i.e., stenosis) should be evaluated for possible revascularization, either by carotid endarterectomy or by carotid artery stenting.
- #1https://bpac.org.nz/bpj/2011/october/tia.aspx
A transient ischaemic attack (TIA) is a medical emergency due to the high risk that stroke will occur within the next 48 hours. […] Patients should immediately be given aspirin, a statin and an antihypertensive medicine (if there are no contraindications). […] All patients with a suspected TIA should have their risk of stroke assessed using the ABCD2 tool, and then be referred to secondary care for urgent investigation and treatment (according to local protocols). […] As soon as a diagnosis of TIA is confirmed, risk factors should be assessed and a long-term, individualised secondary prevention plan implemented. […] If a TIA is rapidly diagnosed and appropriate interventions initiated, the risk of subsequent stroke can be significantly reduced. […] Due to the high risk of stroke following a TIA, it is important that all people with a suspected TIA receive urgent treatment and referral for secondary care assessment.
- #1 6. Antiplatelet Therapy for Ischemic Stroke and Transient Ischemic Attack | Canadian Stroke Best Practiceshttps://www.strokebestpractices.ca/recommendations/secondary-prevention-of-stroke/anti-platelet-therapy-in-ischemic-stroke-and-tia
For patients with a recent stroke or transient ischemic attack due to symptomatic intracranial atherosclerotic stenosis of 70-99%, and a low estimated bleeding risk, the SAMMPRIS protocol should be considered, which includes dual antiplatelet therapy (acetylsalicylic acid and clopidogrel) for the first 3 months, typically followed by antiplatelet monotherapy thereafter, in addition to intensive lipid-lowering therapy with high-dose statin, blood pressure treatment, and structured lifestyle modification addressing smoking cessation, exercise and diet [Evidence Level B]. […] Antiplatelet agents are considered a fundamental component of secondary stroke prevention. Several clinical trials have shown that antiplatelet medications (such as acetylsalicylic acid) reduce the risk of further vascular events after transient ischemic attack or ischemic stroke (25 percent relative risk reduction).
- #1 6. Antiplatelet Therapy for Ischemic Stroke and Transient Ischemic Attack | Canadian Stroke Best Practiceshttps://www.strokebestpractices.ca/recommendations/secondary-prevention-of-stroke/anti-platelet-therapy-in-ischemic-stroke-and-tia
All patients with acute ischemic stroke or transient ischemic attack not already on an antiplatelet agent should be treated with at least 160 mg of acetylsalicylic acid immediately as a one-time loading dose after brain imaging has excluded intracranial hemorrhage [Evidence Level A]. […] For transient ischemic attack or minor ischemic stroke patients who are being discharged from the emergency department, antiplatelet therapy should be started prior to discharge [Evidence Level C]. […] For patients with ischemic stroke or transient ischemic attack, antiplatelet therapy is recommended for long-term secondary stroke prevention to reduce the risk of recurrent stroke and other vascular events unless there is an indication for anticoagulant therapy [Evidence Level A]. […] Antiplatelet therapy should be started as soon as possible after brain imaging has excluded hemorrhage, within 24 hours of symptom onset (ideally within 12 hours) [Evidence Level B].
- #1 6. Antiplatelet Therapy for Ischemic Stroke and Transient Ischemic Attack | Canadian Stroke Best Practiceshttps://www.strokebestpractices.ca/recommendations/secondary-prevention-of-stroke/anti-platelet-therapy-in-ischemic-stroke-and-tia
For long-term secondary stroke prevention, either acetylsalicylic acid (80 mg 325 mg daily), or clopidogrel (75 mg daily), or combined acetylsalicylic acid and extended-release dipyridamole (25mg/200 mg BID), are all appropriate treatment options and selection depends on patient factors or clinical circumstances [Evidence Level A]. […] For patients with an acute high-risk transient ischemic attack or minor ischemic stroke of non-cardioembolic origin (NIHSS 0-3), who are not at high bleeding risk, dual antiplatelet therapy is recommended with clopidogrel 75 mg daily plus acetylsalicylic acid 81 mg daily for a duration of 21 days after the event, followed by antiplatelet monotherapy thereafter (acetylsalicylic acid or clopidogrel alone) [Evidence Level A]. […] Dual antiplatelet therapy for longer than the first 21 days following a transient ischemic attack or minor stroke is not recommended unless there is a specific indication (e.g., arterial stent; symptomatic intracranial artery stenosis), due to an increased risk of bleeding without clear benefit beyond 21 days [Evidence Level B].
- #1 Patient education: Transient ischemic attack (Beyond the Basics) – UpToDatehttps://www.uptodate.com/contents/transient-ischemic-attack-beyond-the-basics
Anticoagulant therapy is usually recommended for selected people with an irregular heart rhythm (atrial fibrillation) who have had a TIA or are at risk for a TIA or stroke. […] Revascularization usually refers to an invasive procedure that opens a partially blocked artery in the neck (the carotid artery), which reduces the risk of stroke.
- #1 NHSAAA Medicines – Secondary Prevention of Stroke and Transient Ischaemic Attack (TIA)https://aaamedicines.org.uk/guidelines/cardiovascular-system/secondary-prevention-of-stroke-and-transient-ischaemic-attack-tia/
Patients admitted on anticoagulants should have them suspended until an emergency CT brain scan has been completed and haemorrhage excluded. […] Anticoagulants are initiated or resumed broadly as follows: TIA – immediately after CT brain excludes bleed. […] After the acute stroke phase, all patients with a BP 130mmHg systolic should be considered for antihypertensive treatment. […] Unless contraindicated, treat all patients who have had an ischaemic stroke with a statin regardless of baseline cholesterol concentration. […] In very frail patients with limited life expectancy, some elements of secondary prevention may cause more harm than benefit. […] Premenopausal women with stroke and TIA should not be offered the combined oral contraceptive pill. […] Post-menopausal women with ischaemic stroke or TIA should not be offered hormone replacement therapy for secondary vascular prevention.

Elevated blood pressure (above 140/90 mm Hg) is the most important treatable risk factor for TIA and stroke. Antihypertensive drugs reduce the risk of strokes, regardless of whether patients have hypertension. […] Important new guidelines from the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) require lifestyle modifications (weight reduction, sodium restriction, regular aerobic activity, limited alcohol intake) to prevent cardiovascular disease in prehypertensive patients with a systolic blood pressure of 120 to 139 mm Hg or a diastolic blood pressure of 80 to 89 mm Hg. […] In most patients, blood pressure should not be treated aggressively immediately (i.e., within the first 24 hours) after a stroke or TIA unless the systolic blood pressure is higher than 220 mm Hg or the diastolic blood pressure is above 120 mm Hg.
- #1 Preventing Stroke in Patients with Transient Ischemic Attacks | AAFPhttps://www.aafp.org/pubs/afp/issues/1999/1115/p2329.html
Current theories on the pathogenesis of TIA suggest that effective measures to prevent stroke should also prevent the recurrence of TIA. The initial approach is to modify risk factors that are amenable to treatment. […] The Stroke Council of the American Heart Association has recommended aggressive treatment of chronic hypertension to maintain the systolic blood pressure below 140 mm Hg and the diastolic blood pressure below 90 mm Hg. […] Cigarette smoking is associated with an increased risk of stroke. Hence, patients should be strongly encouraged to stop smoking. […] Atrial fibrillation is one of the strongest independent risk factors for stroke. […] Some form of stroke prevention therapy must be provided for all patients with TIA. Agents appropriate for this use include aspirin, ticlopidine (Ticlid), clopidogrel (Plavix) and warfarin.

In the Perindopril Protection Against Recurrent Stroke Study (PROGRESS), patients with stroke or TIA within the previous five years were given placebo or combination therapy consisting of perindopril (an ACE inhibitor) and indapamide (a diuretic). In both hypertensive and non-hypertensive patients, the drug combination resulted in a 43 percent reduction in the relative risk of recurrent stroke (four-year follow-up). […] A meta-analysis of 32 studies found that the risk of stroke in persons of either sex and all ages was 50 percent higher in smokers than in nonsmokers. Therefore, the family physician should make a vigorous attempt, at every clinic visit, to implement a smoking cessation plan, particularly in the patient who has had a TIA. […] Diabetes mellitus, independent of its association with hypertension, increases the overall risk of stroke by approximately 25 to 50 percent.

Unless contraindicated, treat all patients who have had an ischaemic stroke with a statin regardless of baseline cholesterol concentration. […] All stroke or TIA patients with symptoms potentially related to their carotid artery circulation territory should have carotid imaging requested immediately and the results discussed with the Stroke Consultant. […] In a patient with moderate to severe (50% stenosis) carotid disease, discuss immediately with the local stroke team to assess need for further imaging, suitability for surgery and the need for any alteration in secondary prevention medication. […] All stroke or TIA patients who do not have already known AF should be investigated for possible AF with a request made for 72 hour ambulatory ECG monitoring.

Increased public awareness is mandatory to admit patients in an emergency department or stroke unit and to gain better support for an update of healthcare facilities all over Europe and beyond for full work-up and best stroke prevention. […] Several different treatments have been shown to independently improve long-term outcome and stroke prevention. Antiplatelet therapy should be immediately used in patients found to have non-cardioembolic TIAs. […] Statins are also effective in reducing recurrent stroke risk, as shown by the Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial, and should be administered immediately after TIAs. […] It is very important to stress that early identification, work-up and treatment of TIAs play an essential role in the effective stroke risk reduction.

The AHA/ASA guidelines recommend a TIA/stroke workup within 48 hours of the index event, whereas the ESO guidelines recommend this workup be completed within 24 hours. […] The AHA/ASA guidelines recommend CEA for symptomatic moderate (50-69%) carotid stenosis depending on patient-specific factors including age and sex, whereas the ESO guidelines recommend CEA for symptomatic moderate stenosis independent of age and sex. […] The AHA/ASA guidelines recommend consideration of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in very high-risk patients, whereas the ESO guidelines note that there is continued uncertainty regarding the use of PCSK9 inhibitors to reduce the risk of recurrent stroke. […] Areas of residual uncertainty include the timing of anticoagulation for AF after stroke; whether patent foramen ovale (PFO) closure is superior to long-term anticoagulation for secondary stroke prevention; and whether PFO closure is indicated in patients 60 years old.

Once your healthcare professional learns the cause of the transient ischemic attack, the goal of treatment is to correct the issue and prevent a stroke. You may need medicines to prevent blood clots. Or you might need surgery. […] Several medicines may lower the risk of stroke after a TIA. Your healthcare professional recommends a medicine based on what caused the TIA, where it was located, its type and how bad the blockage was. […] If the carotid artery in the neck is very narrowed, your healthcare professional may suggest a surgery called carotid endarterectomy (end-ahr-tur-EK-tuh-me). This preventive surgery clears carotid arteries of fatty deposits before another TIA or stroke can occur. […] Some people need a procedure called carotid angioplasty and stent placement. This procedure involves using a balloon-like device to open a clogged artery. Then a small wire tube called a stent is placed into the artery to keep it open.

Anticoagulant medicines can help to prevent blood clots by changing the chemical composition of your blood in a way that stops clots from forming. […] If you have high blood pressure, you’ll be offered a type of medicine called an antihypertensive to control it. This is because high blood pressure increases your risk of having a TIA or stroke. […] If you have high cholesterol, you’ll be advised to take a medicine known as a statin. Statins may also help to reduce your risk of a stroke whatever your cholesterol level is. […] By unblocking the carotid arteries when they have become moderately or severely narrowed, a carotid endarterectomy can significantly reduce the risk of having a stroke or another TIA.

The good news is that healthy lifestyle habits can protect your health and lower your risk of stroke and TIA. These habits will help you to keep a healthy weight, prevent or manage high blood pressure, manage stress and much more. […] Talk to your doctor about a stroke prevention plan. Discuss treating any medical conditions that may affect your risk and which lifestyle changes would be best for you. […] Take your medications as prescribed managing your medications for medical risks will help you to avoid a stroke or TIA. […] Make healthy food choices eat more vegetables, fruits and whole grains. Eat mostly homemade meals using whole, natural foods. Limit salt, sugar and processed food (like canned soup, cold cuts, frozen meals). […] Be more active aim for 150 minutes a week of physical activity, made up of 10-minute bouts (or more) 4-7 days per week. Look for chances to be more active in your daily routine, such as brisk walking or taking the stairs instead of an escalator. Before starting a physical activity program, speak to your healthcare provider about a plan that is right for you.

The best way to help prevent a TIA is to eat a healthy diet, exercise regularly, and not smoke or drink too much alcohol. […] If you’ve already had a TIA, making these changes can help reduce your risk of having a full stroke or another TIA in the future. […] Smoking significantly increases your risk of having a TIA or stroke. This is because it narrows your arteries and makes your blood more likely to clot. […] If you stop smoking, you can reduce your risk of having a TIA or stroke. […] Excessive alcohol consumption can lead to weight gain, high blood pressure, and an irregular heartbeat (atrial fibrillation), all of which can increase your risk of having a TIA or stroke. […] If you’ve been diagnosed with a condition that’s known to increase your risk of TIAs and strokes, such as high cholesterol, high blood pressure, atrial fibrillation or diabetes, it’s important to control the condition.

Heavy alcohol consumption also has links with ischemic stroke, particularly if a person has other risk factors. […] Diet and nutrition play an important role in stroke prevention as they can influence many aspects of health. […] There are several diet types that may help reduce the risk of stroke. One of the most well-researched is the Mediterranean diet, which can reduce the risk of stroke by around 40% or more in people at high risk, according to a 2019 article. […] Physical inactivity has links with an increased chance of stroke. Similarly to a healthy diet, getting regular exercise has multiple benefits for reducing the risk. […] In addition to taking steps to lower the risk of stroke, people can also reduce the risk of other conditions that may contribute to it. […] Many of the risk factors for a stroke after TIA are things a person can control. With preventative medications, dietary changes, exercise, and management of coexisting conditions, people may be able to significantly reduce their risk of having a full stroke.
- #1 Stroke Preventionhttps://ebaptisthealthcare.org/health/articles/stroke-prevention
Take anticoagulants, as prescribed by your doctor, if you have atrial fibrillation or have had a heart attack with other complications. […] Maintain a healthy weight. Being overweight increases your risk of developing high blood pressure, heart problems and diabetes, which are risk factors for TIA and stroke. […] Eat a nutritious, balanced diet low in cholesterol, saturated fats and salt. […] Limit your alcohol. Low to moderate alcohol consumption (from one drink per week to less than two drinks per day) may decrease the risk of ischemic stroke. […] Avoid cocaine and other illegal drugs. Cocaine can increase blood pressure and cause the heart to beat more rapidly, thereby increasing your risk of stroke. […] Avoid birth control pills if you have other risk factors. If you smoke or have high cholesterol or a history of blood clots, taking birth control pills increases your risk of having a stroke. […] Avoid hormone replacement therapy. In women who have gone through menopause, hormone replacement therapy has been shown to slightly increase the risk of stroke.

Stick to an exercise routine. Typically, you need at least 150 minutes of medium-level cardio, like brisk walking, each week. Check with your doctor to see what’s safe for you. […] Stay at a healthy weight. If you are unsure of what weight is best for you, a good range is a body mass index of 18.5 to 24.9. (For example, a person who is 5 feet, 9 inches tall could weigh from 125 to 168 pounds and be in this range.) Another measure to take could be waist size. For men or people assigned male at birth (AMAB), waist circumference should be 40 inches or less. For women or people assigned female at birth (AFAB), waist size should be 35 inches or less. This will help with your blood pressure and cholesterol, too. […] Stop smoking. Tobacco harms your health in many ways, including raising your stroke risk.

Recent data from the Microalbuminuria, Cardiovascular, and Renal Outcomes in HOPE (MICRO-HOPE) sub-study indicate that ramipril therapy reduces cardiovascular and cerebrovascular events in patients with diabetes mellitus and one cardiac risk factor. In MICRO-HOPE, stroke events were reduced by 33 percent, and stroke-related deaths were reduced by 37 percent. […] Currently available antiplatelet agents for stroke prophylaxis include aspirin, clopidogrel (Plavix), ticlopidine (Ticlid), and aspirin-dipyridamole (Aggrenox). […] Aspirin therapy after a stroke or TIA reduces the long-term relative risk of stroke and increases the chance of a full recovery. […] Anticoagulation therapy is appropriate in patients with high-risk cardioembolic conditions. These conditions include atrial fibrillation, a known cardioembolic source (confirmed thrombus), or a suspected cardioembolic source (recent large myocardial infarction, mechanical valve, dilated cardiomyopathy, rheumatic mitral valve stenosis).

A transient ischemic attack (TIA) is a transient episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction. […] The goals of the physical examination are to uncover any neurologic deficits, to evaluate for underlying cardiovascular risk factors, and to seek any potential thrombotic or embolic source of the event. […] The following should be done urgently in patients with TIA: Evaluation, Risk stratification (eg, with the California or ABCD score), Initiation of stroke prevention therapy. […] In view of the high short-term risk of stroke after TIA, antithrombotic therapy should be initiated as soon as intracranial hemorrhage has been ruled out. […] Stroke prevention medication typically recommended for cardioembolic TIA is as follows: For patients with atrial fibrillation after TIA, long-term anticoagulation with warfarin (target international normalized ratio [INR], 2-3); aspirin 325 mg/day for those unable to take oral anticoagulants.

Transient Ischemic Attacks (TIAs) are a serious medical condition with a significant risk of subsequent stroke. […] Education campaigns targeting both the public and healthcare providers have shown promise in increasing awareness and improving recognition rates. […] A support program for patients post-TIA or stroke has shown positive effects on adherence to secondary prevention measures, though its impact on recurrence rates remains to be fully established. […] Since these studies were able to correlate better clinical outcomes with informational campaigns, they demonstrate the benefit of awareness and education in the pre-hospital setting. […] The successful integration of a variety of screening methods in the prehospital setting demonstrates a tangible step forward in stroke recognition, underscoring the potential for targeted educational interventions to enhance early diagnosis and improve outcomes in stroke care.

Transient Ischemic Attack (TIA) is a medical emergency. […] Despite its seemingly mild course, TIA is a serious predictor of subsequent ischemic stroke and death. […] Evaluation of TIA and initiation of multimodal therapeutic interventions should be urgent to reduce the risk of subsequent stroke. […] Immediately start multimodal therapeutic intervention. […] Treatment can significantly reduce the risk of recurrent stroke or TIA (by 80%). […] Antiplatelet drugs (aspirin, clopidogrel, or ticagrelor) in the prevention of non-cardioembolic TIA. […] Anticoagulation is the preferred treatment for cardioembolic TIA or stroke (due to atrial fibrillation or other embolic sources). […] Start blood pressure treatment (long-term target BP 130/80 mm Hg, with ACE inhibitors being the preferred due to their protective effects on cerebrovascular health). […] Treat dyslipidemia and manage other vascular risk factors.

In the past two decades, we have seen major advances in the treatment of transient ischemic attack (TIA) and acute ischemic stroke. […] Effective treatment of TIA and stroke requires an integrated, systematic approach that begins in the ED, continues in the inpatient setting, and is maintained after discharge. […] One reason for the under-use of advanced treatments may be that the symptoms associated with transient ischemic attack (TIA) and stroke are not always recognized as serious. […] Effective treatment of TIA and stroke requires a rapid, integrated, systematic approach, beginning with arrival of the patient at the ED and continuing with acute and subacute management in the inpatient setting through to long-term management to prevent secondary strokes. […] Prompt diagnosis and management of TIA may reduce future stroke rates.
- #1 Drugs in secondary stroke preventionhttps://australianprescriber.tg.org.au/articles/drugs-in-secondary-stroke-prevention.html
Patients with atrial fibrillation should be anticoagulated. Combinations of anticoagulants and antiplatelets should be avoided if possible.

Transient ischemic attacks (TIAs) are associated with a high risk of subsequent stroke and often pose a diagnostic and treatment challenge. […] Management should take place in a stroke-specialized center and consist of rapid assessment and identification of those patients at highest risk for subsequent strokes, including extensive brain and vascular imaging as well as cardiological assessment. […] Based on these work-up results, best suitable prevention should start immediately, usually consisting of antiplatelet agents, anticoagulation, statins, antihypertensive, and/or antidiabetic drugs and lifestyle modifications, including cessation of smoking. […] Studies have demonstrated that such an optimal management can reduce the risk of stroke following TIA by up to 80%. […] Since TIAs are not a benign entity, all efforts should be made to quickly and efficiently manage patients after onset and despite full recovery from signs or symptoms.

Transient ischemic attacks (TIAs) are often incorrectly called mini-strokes, but theyre every bit as serious as a true stroke. […] A TIA is a medical emergency you shouldnt ignore. More importantly, its a chance to get treatment that can prevent a future stroke. […] A transient ischemic attack is a medical emergency just like a stroke is. […] A TIA can be the precursor to a stroke, so get medical attention right away! […] The main reason that a TIA is a medical emergency is because its often a warning that a stroke is possible or even imminent. Up to 20% of people who have a TIA have a stroke within 90 days, and half of those strokes happen within the first two days after a TIA. […] A TIA, by definition, is a temporary issue. But it indicates that a stroke which isnt temporary could happen. That means treating the condition(s) that caused the TIA can help prevent a stroke.
- #2 TIA (Transient Ischemic Attack): Symptoms & Treatmenthttps://my.clevelandclinic.org/health/diseases/14173-transient-ischemic-attack-tia-or-mini-stroke

The management of TIAs focuses on addressing underlying pathologies to help decrease the risk of subsequent TIA or stroke. […] Therapies should emphasize a combination of dietary modifications, exercise, and pharmacologic therapies. […] Studies have shown that early interventions post-TIA may help mitigate the risk of future stroke by 80-90%. […] A heart-healthy diet is crucial in supporting the management of TIA risk factors because it helps manage key risk factors. […] By focusing on nutrient-dense foods, the diet can help support healthy blood pressure, manage LDL („bad”) cholesterol, improve insulin sensitivity, and maintain a healthy body weight. […] There are various natural dietary and herbal supplements that may promote heart health, support healing from TIAs, and help reduce the risk of future stroke.

The primary objective of evaluating patients with TIA is prevention of subsequent ischemic stroke, clinicians should consider that entity a medical emergency and institute a quick and efficient diagnostic evaluation. […] The degree of stroke post-TIA risk varies by patient characteristics and etiopathogenic mechanism. […] Early antithrombotic therapy leads to an about 80% relative reduction of stroke risk in patients with TIA. […] Dual antiplatelet therapy is also an important therapeutic consideration in the management of patients with TIA. […] Patients with TIA etiologically associated with an ipsilateral extracranial carotid atherosclerotic lesion causing more than 50% diameter reduction (i.e., stenosis) should be evaluated for possible revascularization, either by carotid endarterectomy or by carotid artery stenting.

Patients diagnosed with a transient ischemic attack or minor ischemic stroke who are not candidates for hyperacute treatment with intravenous thrombolysis or endovascular thrombectomy may then be prioritized for secondary prevention of stroke assessment and management. […] The goal of outpatient management of transient ischemic attack and non-disabling ischemic stroke is rapid assessment and management to reduce the risk of a recurrent, possibly more serious, event. […] Timely initiation of secondary prevention medical therapy and carotid endarterectomy has been shown to significantly reduce the risk of major stroke after an initial transient ischemic attack or non-disabling stroke. […] Education for the public and healthcare professionals (primary, acute and specialists) about the urgency of assessment and management of transient ischemic attack or non-disabling ischemic stroke is critical to reduce the risk of recurrent, potentially more serious events.
- #2https://bpac.org.nz/bpj/2011/october/tia.aspx
Patients with TIA should be given aspirin, statin and antihypertensive treatment immediately after symptoms have resolved, without waiting for secondary care assessment. […] Following TIA the risk of stroke is dangerously elevated. […] All patients with a confirmed TIA require primary care follow-up (often in conjunction with secondary care) to establish an individual treatment plan for long-term stroke risk reduction. […] People who have had a TIA require individual strategies to modify identified risk factors. […] Long-term preventative treatment includes: Antiplatelet treatment, Anticoagulation (for people with atrial fibrillation), Blood pressure lowering treatment, Cholesterol lowering treatment, Nicotine replacement treatment or other smoking cessation aids. […] Following a TIA, and provided the patient does not have atrial fibrillation (AF), commence antiplatelet treatment (if not taking an anticoagulant).

Long-term treatment with both mono and dual antiplatelet therapy has been shown to reduce the risk of recurrent vascular events in persons with previous cardiovascular/cerebrovascular events. […] The short-term use of the combination of clopidogrel + aspirin vs. aspirin alone, has been shown to reduce the risk of additional ischemic vascular events within 90 days. […] Although used more frequently to prevent coronary thrombotic events, ticagrelor is another antiplatelet agent that has been shown to reduce the risk of ischemic stroke when used as both a monotherapy (compared with aspirin) and in combination with aspirin. […] The use of antithrombotic agents in patients who have experienced an ischemic stroke or transient ischemic attack has been shown to reduce the risk of future events.

The randomized, double-blind Dutch study compared the use of low-dose aspirin (30 mg per day) and medium-dose aspirin (283 mg per day). No difference between the two treatments was found for the primary outcomes of death from all vascular causes, non-fatal stroke or nonfatal myocardial infarction. […] The recommended dosage of clopidogrel is 75 mg per day taken with or without food. […] Few studies have investigated the use of warfarin therapy for stroke prevention outside the setting of atrial fibrillation.
- #2 Secondary Prevention of Stroke and Transient Ischemic Attackhttps://pmc.ncbi.nlm.nih.gov/articles/PMC2667676/
The suggestion that patients are especially fragile (susceptible to recurrent stroke) after stroke or TIA has been borne out by several recent studies. […] The risk of recurrent stroke appears to be strongly weighted toward early occurrence. […] These results suggest that patients with a history of stroke or TIA may constitute a population distinct from those with symptomatic CHD or PAD. […] Antiplatelet therapy in these patients should be tailored to what has been shown for secondary stroke protection rather than for myocardial protection. […] Dual antiplatelet therapy for secondary stroke protection, especially with aspirin and clopidogrel, has not been shown to be beneficial versus aspirin alone, and could result in greater bleeding complications. […] Currently, the only therapy that has been shown to be better than aspirin alone for the prevention of recurrent stroke is the combination of aspirin plus ER-DP.
- #2 GGC Medicines – Secondary prevention of Stroke and Transient Ischaemic Attack (TIA)https://handbook.ggcmedicines.org.uk/guidelines/cardiovascular-system/secondary-prevention-of-stroke-and-transient-ischaemic-attack-tia/
Secondary prevention of stroke should be considered in all patients as soon as possible after their stroke or TIA. […] Initiation of secondary prevention investigations and treatment should be guided by the stroke team, therefore, ensure that all new stroke or TIA patients are referred to the local stroke service via the TrakCare referral form. […] DAPT (aspirin and clopidogrel) can be used in people with non-cardioembolic minor ischaemic stroke (NIHSS score of 3 or less) or high-risk TIA (ABCD score of 4 or more) in the past 24 hours, if diagnosis is confirmed by a stroke specialist and brain imaging has excluded intracerebral haemorrhage (ICH). […] DAPT is usually used for 21 days, then the patient continues on clopidogrel 75mg daily for long-term treatment. […] After the acute phase, all patients with a BP 130mmHg systolic or 80mmHg diastolic should be considered for a long-acting angiotensin-converting enzyme inhibitor (ACEI) and a diuretic (e.g. bendroflumethiazide), if tolerated and not contraindicated.

For patients with TIA and non-valvular atrial fibrillation, antithrombotic therapy is crucial. Oral anticoagulants, particularly non-vitamin K antagonist oral anticoagulants (NOACs), are preferred over vitamin K antagonists due to their lower risk of major bleeding and mortality. […] Despite the availability of effective secondary prevention therapies, adherence to these measures remains suboptimal, particularly in patients with TIA. […] Effective management of TIA involves a multifaceted approach, including the use of antiplatelet agents, antihypertensive medications, and antithrombotic therapy for patients with atrial fibrillation. […] Adherence to evidence-based secondary prevention measures after a transient ischemic attack is consistently lower, representing a missed opportunity to reduce the risk of recurrent stroke.

Patients admitted on anticoagulants should have them suspended until an emergency CT brain scan has been completed and haemorrhage excluded. […] Anticoagulants are initiated or resumed broadly as follows: TIA – immediately after CT brain excludes bleed. […] After the acute stroke phase, all patients with a BP 130mmHg systolic should be considered for antihypertensive treatment. […] Unless contraindicated, treat all patients who have had an ischaemic stroke with a statin regardless of baseline cholesterol concentration. […] In very frail patients with limited life expectancy, some elements of secondary prevention may cause more harm than benefit. […] Premenopausal women with stroke and TIA should not be offered the combined oral contraceptive pill. […] Post-menopausal women with ischaemic stroke or TIA should not be offered hormone replacement therapy for secondary vascular prevention.

Transient Ischemic Attack (TIA) is a medical emergency. […] Despite its seemingly mild course, TIA is a serious predictor of subsequent ischemic stroke and death. […] Evaluation of TIA and initiation of multimodal therapeutic interventions should be urgent to reduce the risk of subsequent stroke. […] Immediately start multimodal therapeutic intervention. […] Treatment can significantly reduce the risk of recurrent stroke or TIA (by 80%). […] Antiplatelet drugs (aspirin, clopidogrel, or ticagrelor) in the prevention of non-cardioembolic TIA. […] Anticoagulation is the preferred treatment for cardioembolic TIA or stroke (due to atrial fibrillation or other embolic sources). […] Start blood pressure treatment (long-term target BP 130/80 mm Hg, with ACE inhibitors being the preferred due to their protective effects on cerebrovascular health). […] Treat dyslipidemia and manage other vascular risk factors. […] Education and counseling are essential; teach patients adaptive coping skills and carefully explain the realistic risk of stroke associated with TIA.

- #3 Recent advances in the management of transient ischemic attackshttps://pmc.ncbi.nlm.nih.gov/articles/PMC9340656/
Transient ischemic attack (TIA) constitutes an important clinical condition, indicating the presence of considerable risk for a subsequent ischemic stroke. Its prompt diagnosis and management have the potential for reducing the risk of neurologic disability, highlighting the critical need to prioritize the care of patients with TIA. […] The diagnosis of transient ischemic attacks (TIAs) is essential to reduce the risk of subsequent ischemic stroke; this risk can be as high as 20% in the 3 months following TIA depending on the causative mechanism of the index cerebrovascular event. Therefore, the goals for evaluation and management of patients suspected of having a TIA are to establish a clinical diagnosis with as much certainty as possible, define the etiologic mechanism of the TIA, risk-stratify the patient for possible subsequent stroke, and implement a management plan to prevent the recurrent event.
