Kardiomiopatia
Leczenie
Leczenie kardiomiopatii wymaga zindywidualizowanego podejścia uwzględniającego typ choroby, nasilenie objawów oraz stan ogólny pacjenta. Farmakoterapia stanowi podstawę terapii i obejmuje inhibitory ACE, ARB, beta-blokery, blokery kanału wapniowego (np. werapamil w HCM), diuretyki, antagonistów aldosteronu, inhibitory SGLT2 oraz leki przeciwarytmiczne i przeciwzakrzepowe. W kardiomiopatii przerostowej stosuje się także mawakamten – inhibitor miozyny poprawiający wydolność wysiłkową u pacjentów z obturacyjną postacią HCM klasy NYHA II-III. W przypadku niewydolności serca z obniżoną frakcją wyrzutową (LVEF ≤50%) zalecane są ARNI (sakubitryl/walsartan) oraz terapia resynchronizująca serca (CRT). Wskazania do wszczepialnego kardiowertera-defibrylatora (ICD) dotyczą pacjentów z wysokim ryzykiem nagłej śmierci sercowej, zwłaszcza z przerostową i rozstrzeniową kardiomiopatią. W zaawansowanych przypadkach rozważane są procedury zabiegowe, takie jak miektomia przegrody, ablacja alkoholowa czy ablacja prądem o częstotliwości radiowej, a także urządzenia wspomagające (LVAD) i ostatecznie przeszczep serca, szczególnie u pacjentów poniżej 70 roku życia bez przeciwwskazań.

Leczenie Kardiomiopatii (Kardiomiopatia)
Leczenie kardiomiopatii to kompleksowy proces, którego główne cele obejmują łagodzenie objawów, poprawę funkcji serca, spowolnienie progresji choroby oraz zapobieganie nagłej śmierci sercowej. Strategie terapeutyczne są dobierane indywidualnie w zależności od typu kardiomiopatii, nasilenia objawów oraz ogólnego stanu zdrowia pacjenta. Chociaż kardiomiopatia jest zazwyczaj chorobą przewlekłą bez możliwości całkowitego wyleczenia, odpowiednie leczenie może znacząco poprawić jakość życia i rokowanie pacjentów.123
Farmakoterapia w leczeniu kardiomiopatii
Leki stanowią podstawę leczenia większości typów kardiomiopatii. Dobór farmakoterapii zależy od typu kardiomiopatii, nasilenia objawów oraz współistniejących schorzeń. Do najczęściej stosowanych grup leków należą:45
- Inhibitory konwertazy angiotensyny (ACE) – rozszerzają naczynia krwionośne, poprawiając przepływ krwi. Szczególnie skuteczne w kardiomiopatii rozstrzeniowej, pomagają zapobiegać dalszemu osłabieniu serca poprzez blokowanie angiotensyny, hormonu, który może uszkadzać mięsień sercowy.56
- Blokery receptora angiotensyny II (ARB) – pomagają rozluźnić i rozszerzyć naczynia krwionośne oraz zmniejszyć retencję soli i wody. Są często zalecane pacjentom z niewydolnością serca z obniżoną frakcją wyrzutową, którzy nie tolerują inhibitorów ACE.78
- Beta-blokery – spowalniają akcję serca i zmniejszają jego obciążenie, zapobiegając zwiększeniu częstości akcji serca w odpowiedzi na stres. Mogą pomóc chronić serce przed dalszym uszkodzeniem. W kardiomiopatii przerostowej zmniejszają objawy duszności i bólu w klatce piersiowej.79
- Blokery kanału wapniowego – rozszerzają naczynia krwionośne, obniżają ciśnienie krwi i dostarczają sercu więcej krwi i tlenu. W kardiomiopatii przerostowej stosowany jest głównie werapamil.1011
- Diuretyki – eliminują nadmiar płynów z organizmu, pomagając zmniejszyć obrzęki i duszność występującą, gdy krew gromadzi się w płucach.712
- Antagonisty aldosteronu – pomagają regulować retencję płynów i zapobiegają nadmiernemu spadkowi poziomu potasu. Mogą także chronić serce przed dalszymi uszkodzeniami.712
- Inhibitory SGLT2 – najnowsza klasa leków, które poprawiają wyniki leczenia u osób z kardiomiopatią, szczególnie rozstrzeniową. Zmniejszają ryzyko hospitalizacji z powodu niewydolności serca i zgonu z przyczyn sercowo-naczyniowych.1314
- Leki przeciwarytmiczne – pomagają kontrolować nieprawidłowy rytm serca, często występujący w kardiomiopatii. Przykładem jest amiodaron.15
- Leki przeciwzakrzepowe – zapobiegają tworzeniu się skrzepów krwi, szczególnie ważne u pacjentów z migotaniem przedsionków lub kardiomiopatią restrykcyjną.1016
- Sakubitryl/walsartan (ARNI) – inhibitor receptora angiotensyny i neprylizyny, zalecany pacjentom z optymalną terapią medyczną, którzy nadal są w klasie NYHA II-III.1718
- Iwabradyna – wskazana dla pacjentów z rytmem zatokowym, u których spoczynkowa częstość akcji serca przekracza 70 uderzeń na minutę pomimo terapii beta-blokerami.17
- Mawakamten – pierwszy w swojej klasie inhibitor miozynowy, zatwierdzony dla dorosłych z objawową obturacyjną kardiomiopatią przerostową klasy NYHA II-III w celu poprawy wydolności wysiłkowej i objawów.192016
Zabiegi i procedury inwazyjne
W przypadkach, gdy leczenie farmakologiczne nie przynosi zadowalających efektów, mogą być rozważane różne procedury zabiegowe:221
- Ablacja przegrody alkoholowa – podczas tej procedury alkohol jest wstrzykiwany przez cewnik do tętnicy zaopatrującej pogrubiały mięsień sercowy. Powoduje to zniszczenie części mięśnia przegrody, zmniejszenie jej grubości i poprawę przepływu krwi. Jest to alternatywa dla chirurgicznej miektomii, szczególnie u starszych pacjentów i tych z wysokim ryzykiem operacyjnym.211922
- Miektomia przegrody – operacja na otwartym sercu, polegająca na usunięciu części pogrubionej przegrody międzykomorowej, co poprawia przepływ krwi i zmniejsza obstrukcję drogi odpływu lewej komory. Często wykonywana jest również naprawa zastawki mitralnej. Jest to preferowana metoda leczenia u odpowiednio wybranych pacjentów z kardiomiopatią przerostową z obturacją, u których leczenie farmakologiczne nie przyniosło poprawy.231624
- Ablacja prądem o częstotliwości radiowej – procedura, w której elektrody na końcówkach cewników przekazują energię o częstotliwości radiowej w celu uszkodzenia (ablacji) małego obszaru tkanki serca powodującego nieprawidłowy rytm serca.2526
Urządzenia wszczepiane
Urządzenia wszczepiane mogą pomóc w kontroli rytmu serca, zapobieganiu nagłej śmierci sercowej i poprawie funkcji serca:13
- Wszczepialny kardiowerter-defibrylator (ICD) – monitoruje rytm serca i dostarcza impulsy elektryczne lub wstrząs elektryczny, gdy wykryje niebezpieczną arytmię. Jest to kluczowe urządzenie w zapobieganiu nagłej śmierci sercowej u pacjentów z wysokim ryzykiem, szczególnie z kardiomiopatią przerostową i rozstrzeniową.2728
- Rozrusznik serca – urządzenie wielkości dwóch monet półdolarowych umieszczone w klatce piersiowej, które wysyła impulsy elektryczne do serca, aby utrzymać regularny rytm. Rozruszniki dwukomorowe są stosowane w leczeniu arytmii spowodowanych niewydolnością serca.2729
- Terapia resynchronizująca serca (CRT) – urządzenie koordynujące skurcze komór serca, ważne w niektórych przypadkach niewydolności serca związanej z kardiomiopatią.3021
- Urządzenie wspomagające lewą komorę (LVAD) – mechaniczna pompa wszczepiona do klatki piersiowej, która pomaga sercu pompować krew. Stosowana w zaawansowanej niewydolności serca jako pomost do przeszczepu serca lub jako terapia docelowa.3132
- CardioMEMS – bezprzewodowe urządzenie mierzące ciśnienie w tętnicy płucnej, pozwalające lekarzowi monitorować funkcję serca i odpowiedź na leki stosowane w niewydolności serca.27
Przeszczep serca
W przypadkach zaawansowanej, opornej na leczenie kardiomiopatii, gdy inne metody leczenia nie przynoszą poprawy, ostateczną opcją może być przeszczep serca.233
Przeszczep serca jest szczególnie rozważany u młodszych pacjentów (zwykle poniżej 70 roku życia), u których nie występują schorzenia ogólnoustrojowe, zaburzenia psychologiczne oraz wysokie, nieodwracalne naczyniowe opory płucne. Ze względu na niedobór serc dawców, kwalifikacja do przeszczepu jest procesem rygorystycznym.3435
Kardiomiopatia przerostowa jest uwzględniona w wytycznych United Network for Organ Sharing (UNOS) dotyczących przeszczepu serca, które przyznają pacjentom z kardiomiopatią przerostową wyższy priorytet ambulatoryjny (Status 4) niż innym ambulatoryjnym kandydatom do przeszczepu z kardiomiopatią niedokrwienną lub rozstrzeniową (Status 6).35
Leczenie specyficznych typów kardiomiopatii
Kardiomiopatia przerostowa (HCM)
Leczenie kardiomiopatii przerostowej koncentruje się na łagodzeniu objawów i zmniejszeniu ryzyka nagłej śmierci sercowej. Podstawowe strategie leczenia obejmują:239
- Leczenie farmakologiczne:
- Beta-blokery są lekami pierwszego rzutu u pacjentów z objawową HCM
- Blokery kanału wapniowego (np. werapamil) są stosowane, gdy beta-blokery nie są tolerowane lub są nieskuteczne
- Dizopiramid może być dodany u pacjentów z objawami opornymi na leczenie beta-blokerem lub blokerem kanału wapniowego
- Mawakamten – nowy lek specyficznie ukierunkowany na HCM, poprawiający wydolność wysiłkową i objawy u pacjentów z obturacyjną postacią choroby1936
- Terapia redukcji przegrody – wskazana, gdy leczenie farmakologiczne nie kontroluje objawów klasy NYHA III lub po omdleniu/stanie przedomdleniowym związanym z obturacją opornym na leczenie farmakologiczne:
- Chirurgiczna miektomia – zapewnia definitywne leczenie objawowej obturacji drogi odpływu lewej komory, wiąże się z niską śmiertelnością i chorobowością pooperacyjną, gdy jest przeprowadzana przez doświadczonych operatorów
- Alkoholowa ablacja przegrody – porównywalna do miektomii chirurgicznej u odpowiednio dobranych pacjentów w specjalistycznych ośrodkach24
- Wszczepialny kardiowerter-defibrylator (ICD) – rozważany w pierwotnej profilaktyce u pacjentów z ciężkim przerostem (≥30 mm), rodzinnym wywiadem nagłej śmierci u krewnego pierwszego stopnia, niedawnym niewyjaśnionym omdleniem lub „wypaloną” HCM (LVEF ≤50%). ICD jest uniwersalnie zalecany w profilaktyce wtórnej u osób, które przeżyły nagłą śmierć sercową lub z utrwalonym częstoskurczem komorowym.28
- Leczenie migotania przedsionków – często występującego u pacjentów z HCM. Ze względu na zwiększone ryzyko powikłań zakrzepowo-zatorowych, zalecana jest doustna antykoagulacja, niezależnie od wyniku w skali CHA2DS2-VASc.3738
Kardiomiopatia rozstrzeniowa (DCM)
Leczenie kardiomiopatii rozstrzeniowej jest zasadniczo takie samo jak leczenie przewlekłej niewydolności serca. Główne strategie obejmują:68
- Leczenie farmakologiczne:
- Inhibitory ACE lub ARB – zalecane od początku w skojarzeniu z beta-blokerem
- Antagonisty receptora mineralokortykoidowego (MRA) – rozważane u pacjentów nadal objawowych przy optymalnej dawce inhibitora ACE i beta-blokera
- ARNI (sakubitryl/walsartan) – zalecany dla pacjentów z optymalną terapią medyczną, tolerujących inhibitory ACE lub ARB, ale nadal w klasie II-III NYHA
- Iwabradyna – wskazana dla pacjentów z rytmem zatokowym, u których spoczynkowa częstość akcji serca przekracza 70 uderzeń na minutę pomimo terapii beta-blokerem
- Inhibitory SGLT2 – zmniejszają ryzyko hospitalizacji i śmiertelności u pacjentów z niewydolnością serca1718
- Terapia urządzeniami:
- ICD – wskazany u pacjentów z utrzymującą się dysfunkcją skurczową pomimo optymalnej terapii medycznej
- Terapia resynchronizująca serca (CRT) – dla pacjentów z istotnym śródkomorowym opóźnieniem przewodzenia32
- Urządzenia wspomagające lewą komorę (LVAD) – stosowane jako pomost do przeszczepu serca lub jako terapia docelowa u wybranych pacjentów
- Przeszczep serca – rozważany u pacjentów z oporną na leczenie niewydolnością serca6
Kardiomiopatia restrykcyjna
Leczenie kardiomiopatii restrykcyjnej jest trudniejsze i koncentruje się głównie na kontroli objawów oraz leczeniu przyczyny podstawowej, jeśli jest znana:3940
- Leczenie przyczynowe:
- Terapia chelacyjna lub flebotomia – może pomóc w leczeniu kardiomiopatii restrykcyjnej spowodowanej nadmiarem żelaza w organizmie
- Przeszczep szpiku kostnego – może być stosowany w leczeniu kardiomiopatii restrykcyjnej spowodowanej amyloidozą40
- Leczenie objawowe:
- Ostrożne stosowanie diuretyków – pacjenci z kardiomiopatią restrykcyjną opierają się na wysokich ciśnieniach napełniania w celu utrzymania rzutu serca, a nadmierna diureza może prowadzić do hipoperfuzji tkanek
- Beta-blokery lub blokery kanału wapniowego – stosowane ostrożnie w celu zwiększenia czasu napełniania lub leczenia arytmii
- Antykoagulacja – zalecana ze względu na podwyższone ryzyko zakrzepicy lewego przedsionka39
Kardiomiopatia amyloidowa
W przypadku amyloidozy sercowej, większość leków wspomagających leczenie niewydolności serca nie jest dobrze tolerowana:41
- Inhibitory ACE i ARB często prowadzą do głębokiego niedociśnienia, nawet w umiarkowanych dawkach
- Beta-blokery i blokery kanału wapniowego mogą nasilać niedociśnienie z powodu ustalonej objętości wyrzutowej i potrzeby wyższej częstości akcji serca dla utrzymania rzutu serca
- Diuretyki pętlowe i antagonisty aldosteronu są podstawą leczenia objawów niewydolności serca, choć wymagają monitorowania zmian kreatyniny i elektrolitów
- Antykoagulacja jest zalecana u pacjentów z migotaniem przedsionków niezależnie od wyniku w skali CHA2DS2-VASC oraz u pacjentów z powiększonym przedsionkiem, nawet w rytmie zatokowym41
Zmiana stylu życia w leczeniu kardiomiopatii
Modyfikacje stylu życia są istotnym elementem leczenia kardiomiopatii, mogą pomóc w kontroli objawów i zapobieganiu powikłaniom:4243
- Dieta sercowo-zdrowa – ograniczenie spożycia soli, zdrowa zbilansowana dieta
- Regularna aktywność fizyczna – dostosowana do stanu pacjenta, po konsultacji z lekarzem. Niektórzy pacjenci, szczególnie z kardiomiopatią przerostową, mogą mieć ograniczenia dotyczące intensywnego wysiłku fizycznego
- Ograniczenie spożycia alkoholu – szczególnie ważne w kardiomiopatii alkoholowej, gdzie całkowite zaprzestanie spożywania alkoholu jest najważniejszym krokiem w leczeniu
- Zaprzestanie palenia tytoniu
- Kontrola masy ciała
- Zarządzanie stresem
- Leczenie chorób współistniejących – takich jak nadciśnienie tętnicze czy cukrzyca, które mogą nasilać kardiomiopatię4244
Nowe kierunki w leczeniu kardiomiopatii
Badania nad nowymi metodami leczenia kardiomiopatii są intensywnie prowadzone, z obiecującymi perspektywami w kilku obszarach:4546
- Terapia genowa – projekt CureHeart finansowany przez BHF ma na celu opracowanie terapii genowych dla kardiomiopatii, umożliwiających naprawę lub wymianę wadliwego genu. Terapia ta będzie dostosowana do konkretnej wady genetycznej pacjenta.46
- Inhibitory sercowej miozyny – leki takie jak mawakamten i CK-274 pokazują obiecujące wyniki w leczeniu obturacji drogi odpływu lewej komory i związanej z kardiomiopatią przerostową rozkurczowej niewydolności serca.45
- Terapia komórkami macierzystymi – badania sugerują, że przeszczepienie komórek macierzystych może poprawić frakcję wyrzutową lewej komory (LVEF), zwiększyć wydolność wysiłkową i złagodzić objawy niewydolności serca u pacjentów z kardiomiopatią rozstrzeniową.4748
- Edycja genów CRISPR/Cas9 – technologia ta może w przyszłości odegrać rolę w zapobieganiu rozwojowi choroby przed pojawieniem się manifestacji klinicznych.4549
- Medycyna spersonalizowana – podejścia koncentrujące się na dostosowaniu leczenia kardiomiopatii rozstrzeniowej do indywidualnych pacjentów w oparciu o ich unikalne profile genetyczne, mechanizmy choroby i odpowiedzi terapeutyczne.50
Kompleksowe podejście do leczenia kardiomiopatii
Skuteczne leczenie kardiomiopatii wymaga kompleksowego podejścia, które łączy farmakoterapię, zabiegi i urządzenia wszczepiane, zmiany stylu życia oraz, w razie potrzeby, przeszczep serca. Kluczowa jest indywidualizacja terapii w zależności od typu kardiomiopatii, nasilenia objawów i współistniejących schorzeń.5152
Chociaż kardiomiopatia jest zazwyczaj chorobą przewlekłą bez możliwości całkowitego wyleczenia, odpowiednie leczenie może znacząco poprawić jakość życia, zmniejszyć objawy i wydłużyć życie pacjentów. Wczesna diagnoza i leczenie podstawowych stanów, które mogą prowadzić do kardiomiopatii, mogą pomóc zapobiec rozwojowi choroby.434
Wraz z postępem badań i rozwoju medycyny, pojawiają się nowe, bardziej ukierunkowane i spersonalizowane terapie, które mogą dalej poprawić rokowanie dla osób zmagających się z tą trudną chorobą serca.5149

Cardiomyopathy and heart failure affect the hearts ability to pump blood and oxygen throughout the body. Your NYU Langone specialist may prescribe medication to improve heart function and manage the symptoms of these conditions. […] Angiotensin-converting enzyme inhibitors also called ACE inhibitors may be prescribed for people who have heart failure with reduced ejection fraction, which is also called dilated cardiomyopathy. These medications widen, or dilate, blood vessels to improve blood flow. They can help prevent further weakening of the heart by blocking angiotensin, a hormone that can damage the heart. […] Angiotensin II receptor blockers help relax and widen blood vessels and reduce salt and water retention. Our doctors may recommend these medications to people with heart failure with reduced ejection fraction who can’t tolerate ACE inhibitors.
- #6 Current Management and Treatment – Dilated Cardiomyopathy – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK553842/
DCM is a common cause of HF and treatment reflects the management of chronic HF. DCM patients, indeed, can be divided into two different classes on the base of the presence of clinical symptoms: Asymptomatic left ventricular systolic dysfunction: in patients with depressed LV systolic function in the absence of symptoms, onset of HF should be delayed or prevented primarily by controlling hypertension and, when the LVEF is 40%, by initiating angiotensin-converting enzyme inhibitor (ACEi) therapy prior to beta-blocker therapy, since the evidences supporting ACEi therapy are stronger. Symptomatic HF with reduced ejection fraction: patients of this category should all be treated. The goals of therapy are to reduce mortality and morbidity; improve symptoms, quality of life, and functional status and decrease hospitalization rate.
- #6 Current Management and Treatment – Dilated Cardiomyopathy – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK553842/
The prevalence of heart failure (HF) is escalating rapidly, consuming significant healthcare resources, inflicts significant morbidity and mortality, and greatly impacts quality of life. Dilated cardiomyopathy (DCM) is a frequent cause of HF and is characterized by a progressive course. Nowadays pharmacological and non-pharmacological therapies have dramatically changed DCMs natural history. […] Patients with a clinical diagnosis of HF and LV dysfunction should receive recommended therapies: beta-blockers (BB), ACE inhibitors (ACEi) or angiotensin receptor blockers (ARB), aldosterone antagonists, and more recently angiotensin receptor-neprilysin inhibitor (ARNI) and ivabradine are established therapies for chronic HF. In case of persistent systolic dysfunction and/or severe intraventricular conduction delay, an ICD and/or CRT are indicated. Finally, heart transplantation and mechanical circulatory support (MCS) are options that can be used in critically ill HF who cant be stabilized by medical therapy alone.

Often prescribed in conjunction with ACE inhibitors for heart failure with reduced ejection fraction, beta blockers lessen the hearts workload by preventing the hormone adrenaline from increasing the heart rate in response to stress also known as the fight or flight reaction. These medications can help protect the heart from further damage over time. […] Diuretics may be prescribed for people with any type of heart failure. These medications eliminate excess fluid from the body by encouraging the production of urine. This helps reduce swelling and shortness of breath, which occurs when blood backs up into the lungs. […] Your doctor may also prescribe mineralocorticoid receptor antagonists, which can help regulate fluid retention while ensuring that potassium levels don’t drop too low. These medications also protect the heart from further damage over time.
- #8 Dilated Cardiomyopathy (DCM) Treatment & Management: Approach Considerations, Blood Pressure Control, Angiotensin-Converting Enzyme Inhibitorshttps://emedicine.medscape.com/article/152696-treatment
Treatment of DCM is essentially the same as treatment of chronic HF and pulmonary edema; however, obtaining a thorough history from patients with DCM helps determine the etiology. […] Mainstays of medical therapy are preload reduction, afterload reduction, diuresis, and airway support. […] Appropriate control of blood pressure is essential to effective therapy for persons with HF. […] Use of angiotensin-converting enzyme (ACE) inhibitors has been the criterion standard in the treatment of left ventricular dysfunction. […] ACE inhibitors have been shown to decrease mortality in both symptomatic and asymptomatic patients with left ventricular dysfunction and to reduce readmissions caused by HF. […] Data have demonstrated that angiotensin II receptor blockers (ARBs) are as effective as angiotensin-converting enzyme (ACE) inhibitors in the treatment of HF.

- #9 Treatment of Hypertrophic Cardiomyopathy: What Every Cardiologist Needs to Knowhttps://www.acc.org/Latest-in-Cardiology/Articles/2020/02/19/18/19/Treatment-of-Hypertrophic-Cardiomyopathy
Treatment of Hypertrophic Cardiomyopathy: What Every Cardiologist Needs to Know […] Hypertrophic cardiomyopathy (HCM) is an inherited disease of the cardiac sarcomere that results in left ventricular hypertrophy, hyperdynamic function, microvascular dysfunction, impaired relaxation, and myocardial fibrosis. Clinical hallmarks include left ventricular outflow tract obstruction (LVOTO), arrhythmias, and heart failure. To date, no disease-modifying therapies have been identified, although clinical trials of novel therapeutics are in progress. This analysis focuses on HCM management strategies fundamental to the care of patients with HCM: LVOTO, sudden cardiac death (SCD), atrial fibrillation, exercise restriction, and heart failure. […] A significant proportion of HCM patients suffer from LVOTO; therefore, investigating obstruction with both resting echo (with Valsalva) and stress echo if the gradient is below 50mmHg on rest interrogation should be performed. Treatment of obstruction is indicated for symptomatic patients (NYHA Class II) and medical therapy is the first-line approach. Importantly, patients may become accustomed to their reduced functional capacity and minimize symptoms, making objective confirmation of functional capacity with cardiopulmonary exercise testing a useful adjunct to history-taking for assessment of exertional intolerance. Medical therapies include beta-blockade and verapamil alone or in combination, though verapamil may increase LVOTO-associated symptoms in some individuals due to its vasodilatory effect. Disopyramide may be added for patients with symptoms refractory to the use of beta-blocker or calcium channel blocker therapy.
- #10 Cardiomyopathy | Causes, Symptoms, Types & Treatmenthttps://www.cincinnatichildrens.org/health/c/cardiomyopathy
The more chronic treatment options for hypertrophic cardiomyopathy address both the heart rhythm problems and obstruction of flow problems. Treatment for outflow obstruction can include medicines such as beta blockers (atenolol, metoprolol) and calcium channel blockers (verapamil), designed to slow the heart rate and „relax” the heart, thereby decreasing the obstruction. […] Patients with restrictive cardiomyopathy are at high risk for blood clots within the heart, particularly the enlarged upper chambers. Blood thinners such as aspirin, coumadin (warfarin) or Lovenox may be needed. Gentle use of diuretics can also help some patients. Internal Cardioverter / Defibrillators (ICDs) are also used because these patients are at risk for sudden cardiac arrest related to fast or slow rhythms. […] Patients with ACM can benefit from treatment with medicines to limit abnormal rhythms. Treatment also consists of placement of an ICD to protect against sudden cardiac events such as a cardiac arrest. In certain cases, a catheter-based procedure to eliminate the abnormal rhythm can be performed.
- #11 Hypertrophic Cardiomyopathy – Cardiovascular Disorders – MSD Manual Professional Editionhttps://www.msdmanuals.com/professional/cardiovascular-disorders/cardiomyopathies/hypertrophic-cardiomyopathy
Treatment is with beta-blockers, verapamil, disopyramide, mavacamten, and sometimes chemical reduction or surgical removal of outflow tract obstruction. […] Treatment of hypertrophic cardiomyopathy is based on the phenotype. Patients without obstruction generally have a stable clinical course without significant symptoms, although some experience heart failure symptoms due to diastolic dysfunction. Beta-blockers and heart rate-limiting calcium channel blockers with a lower arterial dilation capacity (usually verapamil), alone or combined, are the mainstays. By slowing the heart rate, they prolong the diastolic filling period, which may increase left ventricular filling in patients with diastolic dysfunction. Long-term efficacy of such therapy, however, has not been proven. […] In patients with the obstructive phenotype, in addition to attempts at improving diastolic function, treatment is directed at reducing the outflow tract gradient. Non-dihydropyridine calcium channel blockers (eg, verapamil, diltiazem), beta-blockers, and disopyramide reduce the outflow tract gradient through their negative inotropic effects.

For patients with symptomatic HF, a new therapeutic algorithm has been proposed by the current European guidelines. Neurohormonal antagonists, ACEi or angiotensin II type I receptor blockers (ARB) in case of ACEi intolerance, are recommended from the beginning in association with beta-blocker. The addition of mineralocorticoid receptor antagonists (MRA) should be considered in patients still symptomatic with an optimized dosage of ACEi and beta-blocker. ACEi, ARB, beta-blocker, and MRA have demonstrated, in several clinical trials, to reduce risk of HF hospitalization and death in patient with HF and reduced EF. […] More recently, two new molecules have been included to the recommended pharmacological therapy: an angiotensin receptor-neprilysin inhibitor (ARNI) and the hyperpolarization channel blocker ivabradine. In particular, Sacubitril/Valsartan, tested in PARADIGM trial, is recommended for patients on optimal medical therapy, tolerating ACEi or ARB, but still in IIIII NYHA class. Ivabradine is indicated for patients in sinus rhythm that continue to have a resting heart rate over 70 bpm even on beta-blocker therapy based on SHIFT trial. Both these two drugs have shown to improve survival and reduce hospitalization in patients with HF.

Septal reduction therapy (SRT) is indicated when medical therapy fails to control NYHA Class III symptoms or following LVOTO-associated syncope or near syncope refractory to medical therapy. There are two forms of SRT: surgical myomectomy and alcohol septal ablation. Surgical myectomy provides definitive therapy for symptomatic LVOTO and is associated with low post-operative mortality and morbidity when carried out by experienced operators in expert centers, although no significant long-term mortality benefit has been demonstrated. Given this, pre-operative counseling should emphasize that the benefit is currently limited to symptom improvement. […] With refinement of the techniques and greater experience, post-procedural outcomes following alcohol septal ablation are comparable to surgical myectomy in appropriately selected patients at expert centers. Selecting the right approach to SRT is challenging and should include not only the assessment of provider and center expertise, but also factors such as patient age, comorbid disease, and patient preference. Despite excellent intermediate and long-term results, some patients remain symptomatic or develop heart failure after SRT.

Patients with HCM are at increased risk for SCD, and risk stratification for implantable cardioverter defibrillator (ICD) implantation is critical in this population. Primary prevention with an ICD is reasonable for patients with severe hypertrophy (30mm), family history of sudden death in a first degree relative, recent unexplained syncope, or „burnt-out” HCM (LVEF 50%). The presence of non-sustained ventricular tachycardia on 24-hour Holter or abnormal blood pressure response to exercise, when added to other risk factors, also supports primary prevention ICD. Other risk factors that may influence the decision to place an ICD for primary prevention include marked late-gadolinium enhancement on magnetic resonance imaging (MRI), the presence of an apical aneurysm, and some genetic mutations present in families with high prevalence of sudden cardiac death. Secondary prevention with ICD placement in those surviving SCD or with sustained ventricular tachycardia (VT) is universally recommended. In the case of syncope, a thorough evaluation for provoked obstruction is first required to avoid ICD implantation for syncope related to LVOTO rather than ventricular arrhythmias. Periodic reassessment of risk factors is recommended as part of ongoing follow up, with more frequent testing reserved for younger patients and those with borderline risk factors.

Medication is often an essential component in the management of cardiomyopathy. Commonly prescribed medications include Angiotensin-Converting Enzyme (ACE) Inhibitors, beta-blockers, and the use of diuretics. […] Finally, anticoagulants may be administered in certain circumstances, particularly in cases where cardiomyopathy is linked with atrial fibrillation, to avoid blood clots and lower the risk of stroke. […] Beyond the treatment options listed above, there are a few others that might be considered. These include ICDs, implantable cardioverter-defibrillators, or Cardiac Resynchronization Therapy for heart failure(CRT). CRT involves the implantation of a device that is responsible for coordinating the contractions of the ventricles of the heart. When it comes to some instances of heart failure that are related to cardiomyopathy, this can be useful.

Some patients with HCM develop clinical heart failure, ranging from heart failure with preserved ejection fraction, to severe restrictive cardiomyopathy, to 'burnt-out’ dilated hypertrophic cardiomyopathy. Patients diagnosed with HCM prior to age 40 have more than a 60% chance of experiencing clinical heart failure by age 70, and those diagnosed between ages 40 and 60 have greater than a 40% chance to experience heart failure by that age. However, only 5% of HCM patients will progress to require advanced heart failure therapies during their lifetime. […] Given the predominant restrictive physiology with fixed stroke volume and small left ventricular cavity, patients often do not respond to inotropic support or benefit from implantation of a durable left ventricular assist device (LVAD). This is reflected in the 2018 United Network for Organ Sharing (UNOS) allocation guidelines for heart transplantation, which affords HCM patients higher outpatient priority listing at Status 4 than other outpatient transplant candidates with ischemic or dilated cardiomyopathy, who are Status 6.

Atrial fibrillation can worsen exertional symptoms and increase stroke risk in patients with HCM. The role for catheter ablation has not been specifically studied in HCM cohorts but remains an option for patients with symptoms refractory to medical therapy. As refractory symptomatic atrial fibrillation often marks progressive disease with restrictive physiology, these patients also warrant evaluation for advanced heart failure therapies such as heart transplantation. Due to the increased risk for thromboembolism in HCM patients who develop atrial fibrillation or flutter, oral anticoagulation is recommended as primary stroke prophylaxis regardless of CHA2DS2-VASc score. […] Balancing the overall benefits of exercise in the general population with the potential risk of SCD in the HCM population is a challenge. Strenuous exercise has been routinely discouraged, though there is an increasing appreciation for how the health benefits of exercise should be balanced with the potential risks. Studies to better define the risk of high-intensity exercise in HCM are ongoing, and thoughtful discussion with shared decision making is a widely accepted strategy for application of exercise restrictions in this population.

For heart failure with preserved ejection fraction, the strongest recommendation was to control blood pressure, followed by a 2a recommendation for management of atrial fibrillation to ease symptoms and for use of SGLT2 inhibitors. Selected patients could also be considered for MRAs, ARBs, and sacubitril/valsartan, especially on the lower end of the ejection fraction range. […] For medical management in hypertrophic cardiomyopathy (HCM), the 2020 AHA/ACC guidelines recommended direct oral anticoagulants for persistent or paroxysmal atrial fibrillation as the default, regardless of CHA2DS2VASc score. […] For patients with symptomatic left ventricular outflow tract obstruction (LVOTO), the guidelines gave a class 1 recommendation to nonvasodilating beta-blockers (or nondihydropyridine calcium channel blockers if not tolerated or ineffective) and to the addition of disopyramide in cases of persistent severe symptoms from LVOTO despite those agents.
- #39 What to Know About Medical Therapy for Cardiomyopathy | MedPage Todayhttps://www.medpagetoday.com/medical-journeys/cardiomyopathy/101260
For patients with obstructive HCM, the guidelines gave a class 1 endorsement of vasoconstrictors without inotropic activity (alone or with beta-blockers) for acute hypotension unresponsive to fluid administration and a class 2b recommendation for cautious use of low-dose oral diuretics for persistent dyspnea with volume overload and high left-sided filling pressures. […] For patients with restrictive cardiomyopathy (RCM), aside from treating any identified underlying cause, heart failure management with the usual agents is complicated, noted a review in Circulation Research by Morie Gertz, MD, and colleagues. […] Volume status can be challenging to manage with diuretics, „as patients with RCM rely on high filling pressures to maintain cardiac output and excessive diuresis may result in tissue hypoperfusion,” the authors explained. „The use of beta-blockers or calcium channel blockers to increase filling time or to manage arrhythmias should be carefully introduced, as some patients may be intolerant.”
- #40 Restrictive Cardiomyopathy | Cedars-Sinaihttps://www.cedars-sinai.org/health-library/diseases-and-conditions/r/restrictive-cardiomyopathy.html
The causes of RCM can be hard to treat. The treatment is often centered around the underlying cause. For example, chelation therapy or phlebotomy may help RCM caused by too much iron in the body. Chelation therapy uses drugs that bind to iron and removes it from the body. Phlebotomy removes some of the iron-loaded blood from the body through an IV line. A bone marrow transplant may be used to treat RCM caused by amyloidosis. It replaces cells that make the amyloid proteins. […] Your healthcare provider may prescribe treatments to help reduce your symptoms, such as: […] Water pills (diuretics) to reduce swelling […] Medicine, such as heart-rate-lowering calcium channel blockers or beta-blockers, to reduce the hearts workload and increase its efficiency […] Medicine, such as ACE inhibitors, to help the heart pump better
- #41 What to Know About Medical Therapy for Cardiomyopathy | MedPage Todayhttps://www.medpagetoday.com/medical-journeys/cardiomyopathy/101260
ACE inhibitors and angiotensin II receptor blockers aren’t well proven for these patients and may not be well tolerated. […] On the other hand, most patients stand to benefit from anticoagulation, due to elevated risk of left atrial thrombus. That’s especially the case for cardiac amyloidosis patients, for whom anticoagulation has a class 2a recommendation with atrial fibrillation regardless of CHA2DS2-VASC risk score and for those with an enlarged atrium even when in sinus rhythm, according to a review in Current Treatment Options in Oncology. […] For cardiac amyloidosis, most supportive medications for heart failure management are not well tolerated, the review by Gertz and co-authors noted. „Angiotensin-converting enzyme inhibitors and angiotensin receptor II blockers often lead to profound hypotension, even in modest doses. Beta-blockers and calcium channel blockers may aggravate hypotension because of the fixed stroke volume and need for a higher heart rate to maintain cardiac output.”

There are currently no medical interventions that alter the natural course of HCM, but cardiac myosin inhibitors have shown potential promise. Trials investigating the effect of cardiac myosin inhibitors such as mavacamten and CK-274 on LVOTO and HCM associated diastolic heart failure are underway. Finally, gene-silencing with CRISPR/Cas9 gene-editing technology may someday play a role in the prevention of disease development before the appearance of clinical manifestations. […] In summary, patients with HCM may suffer from LVOTO obstruction, atrial arrhythmias, SCD, and advanced heart failure. Current therapies focus on the disease manifestations, but future therapies may offer hope to effectively address the pathophysiology of HCM.

The BHF funded CureHeart research project aims to find the world’s first cures for inherited cardiomyopathies. […] Researchers at the University of Oxford, led by Professor Hugh Watkins, will develop gene therapies for cardiomyopathy in people with an inherited heart condition. […] CureHeart will use gene therapy which enables the faulty gene to be repaired or replaced to treat cardiomyopathy by targeting the specific fault, to correct the action of the gene in a person’s heart cells. […] Yes. The treatment will target the specific genetic cause of cardiomyopathy in a person or family, and will be tailored to the genetic fault. […] Existing medical treatments for cardiomyopathy are not always effective, and some (such as surgical procedures or devices) can be risky. […] Gene therapy will depend on the type of genetic fault a person has, and the way it acts to change the protein function.

The emerging treatment strategies for DCM are based on regenerative medicine approaches, such as stem cell therapy and gene therapy that have the potential to repair and restore myocardia functioning in patients. […] Stem cell therapy involves transplanting stem cells into the heart to improve cardiac function. Research indicates that stem cell transplantation can improve left ventricular ejection fraction (LVEF), increase exercise capacity, and alleviate symptoms of heart failure in patients with DCM. Various stem cell types have been employed in DCM treatment, such as skeletal myoblasts, hematopoietic stem cells, mesenchymal stem cells, and CD34+ stem cells. Human pluripotent stem cell-derived cardiac cells are being explored for their potential in disease modeling, cell therapy, and drug discovery. However, stem cell therapy effectiveness remains uncertain due to limited high-quality studies and the need for further exploration.

Cardiomyopathy, a disorder of mechanical and electrical cardiac action, is a significant cause of morbidity and mortality in the United States and is seen in both adult and pediatric populations. Traditional treatment for dilated cardiomyopathy largely focuses on symptomatic relief and delayed progression of disease but does not offer a cure or reversal of disease process. […] Because existing management strategies for DCM are not able to fully prevent patients from progressing to heart failure, the use of stem cells offers a promising alternative. […] While stem cell therapy is a rapidly evolving area of research, several methods of stem cell derivation have proven particularly effective in the treatment of DCM. […] Because DCM often causes diffuse dilation, aspects of HSC therapy on other regions of the heart have shown similar promise.

While current dilated cardiomyopathy treatments focus on controlling symptoms and improving heart function, there is a need for more innovative approaches to address the underlying causes of DCM and improve patient outcomes. […] Personalized medicine approaches focus on customizing dilated cardiomyopathy treatments for individual patients based on their unique genetic profiles, disease mechanisms, and therapy responses. These may include gene therapy, gene editing, and targeted treatments. This approach offers several advantages, including improved efficacy and reduced side effects. Personalized dilated cardiomyopathy treatment can be designed to target specific genetic mutations or disease mechanisms, increasing the likelihood of effective therapy. Additionally, personalized dilated cardiomyopathy treatment can help identify patients who are most likely to benefit from a particular therapy, reducing the risk of ineffective or harmful treatments as well as more precise monitoring and adjustment of treatment, enabling clinicians to optimize therapy over time.
