Arterioskleroza / miażdżyca
Etiologia i przyczyny

Arterioskleroza to ogólne stwardnienie tętnic, natomiast miażdżyca jest jej specyficzną formą, charakteryzującą się tworzeniem blaszek miażdżycowych złożonych z lipidów, cholesterolu, wapnia i komórek zapalnych. Proces ten rozpoczyna się od uszkodzenia śródbłonka, co prowadzi do akumulacji lipidów i progresji zmian w ścianie naczynia. Miażdżyca rozwija się latami, często zaczynając już w dzieciństwie, i prowadzi do zwężenia tętnic oraz ryzyka pęknięcia blaszki i powstania zakrzepu. Kluczowe etapy to uszkodzenie śródbłonka, tworzenie pasma tłuszczowego, wzrost blaszki i jej destabilizacja. Czynniki ryzyka obejmują dyslipidemię (wysoki LDL, niski HDL), nadciśnienie tętnicze, palenie tytoniu, cukrzycę, otyłość, brak aktywności fizycznej, niezdrową dietę, wysoki poziom trójglicerydów, nadmierne spożycie alkoholu, stres oraz bezdech senny.

Arterioskleroza / miażdżyca – Etiologia, przyczyny powstawania

Arterioskleroza i miażdżyca (atherosclerosis) to terminy, które czasami są używane zamiennie, jednak istnieje różnica między nimi. Arterioskleroza oznacza ogólnie stwardnienie i utratę elastyczności tętnic z różnych przyczyn, natomiast miażdżyca jest specyficznym rodzajem arteriosklerozy, charakteryzującym się gromadzeniem się blaszek miażdżycowych w ścianach tętnic.123

Podstawowe mechanizmy powstawania miażdżycy

Dokładna przyczyna miażdżycy nie jest w pełni poznana. Uważa się jednak, że choroba rozpoczyna się od uszkodzenia lub urazu wewnętrznej warstwy tętnicy (śródbłonka).123 Miażdżyca jest chorobą postępującą powoli, która może rozpocząć się już w dzieciństwie i nasilać się z wiekiem.45

Kiedy wewnętrzna ściana tętnicy zostaje uszkodzona, krwinki i inne substancje gromadzą się w miejscu urazu. Te substancje tworzą się w wewnętrznej wyściółce tętnicy.6 Z czasem tłuszcze, cholesterol i inne substancje również gromadzą się na i w ścianach tętnic serca. Ta akumulacja jest nazywana blaszką miażdżycową. Blaszkę miażdżycową tworzą tłuszcze, cholesterol, wapń, komórki odpornościowe i inne substancje obecne we krwi.167

Blaszka miażdżycowa może powodować zwężenie tętnic, blokowanie przepływu krwi, a także może pęknąć, prowadząc do powstania zakrzepu krwi.16 Proces ten upośledza normalny przepływ krwi przez organizm, utrudniając dostarczanie tlenu i składników odżywczych do narządów i tkanek.8

Fazy rozwoju miażdżycy

Rozwój miażdżycy przebiega w kilku etapach, które trwają wiele lat i obejmują:9

  1. Uszkodzenie śródbłonka i odpowiedź immunologiczna
  2. Tworzenie się pasma tłuszczowego
  3. Wzrost blaszki miażdżycowej
  4. Pęknięcie lub erozja blaszki

Badania wskazują, że miażdżyca to złożony proces, który często rozpoczyna się w dzieciństwie w postaci drobnych pasm tłuszczowych w tętnicach i postępuje z wiekiem.1011

Czynniki ryzyka miażdżycy

Czynniki ryzyka to warunki lub nawyki, które zwiększają prawdopodobieństwo rozwoju choroby. Prawie połowa Amerykanów ma wysokie ciśnienie krwi, niezdrowy poziom cholesterolu lub pali tytoń. Są to kluczowe czynniki ryzyka, które mogą zapoczątkować gromadzenie się blaszki miażdżycowej.12

Modyfikowalne czynniki ryzyka

Do czynników ryzyka miażdżycy, które można modyfikować, należą:

  • Wysoki poziom cholesterolu – zwłaszcza wysokie stężenie lipoprotein o niskiej gęstości (LDL) i niskie stężenie lipoprotein o wysokiej gęstości (HDL)11314
  • Wysokie ciśnienie krwi – nadciśnienie może uszkadzać ściany tętnic, umożliwiając gromadzenie się blaszki1516
  • Palenie tytoniu – wyroby tytoniowe mogą uszkadzać naczynia krwionośne i serce1718
  • Cukrzyca i insulinooporność – wysoki poziom cukru we krwi może uszkadzać wewnętrzne warstwy tętnic, powodując gromadzenie się blaszki1920
  • Otyłość – zwiększa ryzyko innych czynników, takich jak nadciśnienie, cukrzyca i podwyższony poziom cholesterolu121
  • Brak aktywności fizycznej – siedzący tryb życia i spędzanie dużo czasu przed ekranami są powiązane z niezdrowym poziomem cholesterolu2223
  • Niezdrowa dieta – spożywanie dużej ilości pokarmów bogatych w tłuszcze nasycone, tłuszcze trans, cholesterol, sól i cukier2425
  • Wysoki poziom trójglicerydów – rodzaj tłuszczu we krwi126
  • Nadmierne spożycie alkoholu – może podnosić całkowity poziom cholesterolu2728
  • Stres – przewlekły stres może przyczyniać się do wysokiego ciśnienia krwi i innych czynników ryzyka sercowo-naczyniowego2930
  • Bezdech senny – może zwiększać ryzyko miażdżycy3132

Niemodyfikowalne czynniki ryzyka

Niektóre czynniki ryzyka miażdżycy nie mogą być zmienione, należą do nich:

  • Wiek – u większości osób gromadzenie się blaszki miażdżycowej rozpoczyna się w dzieciństwie i pogarsza się z wiekiem. U mężczyzn ryzyko wzrasta po 45 roku życia, a u kobiet po 55 roku życia.3334
  • Predyspozycje genetyczne – skłonność do miażdżycy wyraźnie występuje rodzinnie, szczególnie przy dziedzicznym zaburzeniu cholesterolu, zwanym hipercholesterolemią rodzinną3536
  • Płeć – mężczyźni mają tendencję do rozwijania miażdżycy w młodszym wieku niż kobiety, choć ryzyko dla kobiet wzrasta po menopauzie3738
  • Rasa i pochodzenie etniczne – ryzyko zgonu z powodu chorób serca u osób czarnoskórych jest o 30% wyższe niż u osób białych. Osoby pochodzenia południowoazjatyckiego również mają wyższe ryzyko chorób serca.39

Stan zapalny a miażdżyca

Coraz więcej dowodów wskazuje na rolę układu immunologicznego i stanu zapalnego w rozwoju miażdżycy.4041 Przewlekłe stany zapalne mogą uszkadzać śródbłonek naczyniowy, prowadząc do powstawania blaszki miażdżycowej.42

Choroby i stany zapalne, które mogą zwiększać ryzyko miażdżycy, to:143

  • Reumatoidalne zapalenie stawów
  • Toczeń rumieniowaty układowy
  • Łuszczyca
  • Zapalne choroby jelit

Wysoki poziom białka C-reaktywnego (CRP) we krwi, który jest markerem stanu zapalnego, może przewidywać zwiększone prawdopodobieństwo zdarzeń niedokrwiennych, choć nie przewiduje wiarygodnie stopnia zaawansowania miażdżycy.4445

Rola infekcji w rozwoju miażdżycy

Zaobserwowano związek między infekcjami a miażdżycą, w szczególności asocjację między serologicznymi dowodami określonych infekcji a chorobą wieńcową (CAD).46 Infekcje niektórymi typami bakterii lub wirusów (takimi jak Helicobacter pylori lub cytomegalowirus) mogą również zwiększać stan zapalny w śródbłonku tętnicy i prowadzić do miażdżycy.47

Mechanizmy patofizjologiczne miażdżycy

Miażdżyca jest inicjowana przez aktywację śródbłonka, po której następuje kaskada zdarzeń (akumulacja lipidów, elementów włóknistych i wapnienia), co wywołuje zwężenie naczynia i aktywację szlaków zapalnych.48

Rola dyslipidemii

Dyslipidemia (wysoki całkowity cholesterol, wysoki LDL lub niski HDL) sprzyja miażdżycy poprzez nasilanie dysfunkcji śródbłonka i szlaków zapalnych w śródbłonku naczyniowym.49 Przewlekłe wysokie stężenie cholesterolu jest głównym czynnikiem przyczyniającym się do miażdżycy.50

Szczególne znaczenie w rozwoju miażdżycy mają:

  • Lipoproteina(a) [Lp(a)] – jest pro-miażdżycowa i stanowi niezależny czynnik ryzyka chorób sercowo-naczyniowych51
  • Apolipoproteina B (apoB) – białko występujące w dwóch izoformach: apoB-100 syntetyzowanej w wątrobie i apoB-46 syntetyzowanej w jelitach52
  • Małe, gęste LDL – charakterystyczne dla cukrzycy, są wysoce miażdżycorodne53

Rola nadciśnienia i cukrzycy

Nadciśnienie może prowadzić do zapalenia naczyń poprzez mechanizmy zależne od angiotensyny II.54 Cukrzyca prowadzi do tworzenia końcowych produktów zaawansowanej glikacji, które zwiększają produkcję cytokin prozapalnych z komórek śródbłonka.55

Przewlekła choroba nerek sprzyja rozwojowi miażdżycy poprzez kilka szlaków, w tym pogorszenie nadciśnienia i insulinooporności; zmniejszone stężenie apolipoproteiny A-I; oraz zwiększone stężenie lipoproteiny(a), homocysteiny, fibrynogenu i białka C-reaktywnego.56

Rola sił hemodynamicznych

Siły hemodynamiczne stanowią lokalny czynnik ryzyka aterogenezy, ponieważ sprzyjają dysfunkcji śródbłonka.57 Liczne dane korelacyjne wskazujące, że niskie ścinanie lub zaburzony przepływ odpowiada za lokalizację zmian miażdżycowych, podkreślają znaczenie rozgałęzień i bifurkacji tętnic przy wykonywaniu diagnostyki rozwoju lub progresji zmian miażdżycowych.58

Dysfunkcja śródbłonka jest również wyjaśniana przez zmniejszenie biodostępności tlenku azotu (NO). NO jest syntetyzowany z L-argininy w komórkach śródbłonka w reakcji katalizowanej przez eNOS i dyfunduje przez błony komórkowe, docierając do tkanki mięśniowej gładkiej ściany tętnicy. NO promuje relaksację włókien mięśni gładkich, znaną jako rozszerzenie naczyń zależne od śródbłonka, i jest uważany za cząsteczkę o działaniu przeciwmiażdżycowym, ponieważ przeciwdziała aterogenezie i jej powikłaniom.59

Genetyka a miażdżyca

Badania wskazują na rolę czynników genetycznych w modulowaniu zapalenia naczyniowego i stabilności blaszki miażdżycowej. Polimorfizmy genetyczne, takie jak polimorfizm PCSK9 (rs2149041), są związane ze zwiększoną grubością błony wewnętrznej i środkowej tętnicy szyjnej (CIMT), która jest markerem wczesnej miażdżycy.60

Geny potencjalnie zaangażowane w choroby sercowo-naczyniowe obejmują APOA1, APOA5, APOB, APOC1, APOC2, APOE, CDKN1A, CXCL12, SCARB1, SMARCA4 i TERT.61 Zidentyfikowano co najmniej 164 loci ryzyka genetycznego związane z miażdżycą.62

Badania genetyczno-epidemiologiczne zidentyfikowały długą listę genetycznych i niegenetycznych czynników ryzyka CAD. Jednak takie badania wskazują, że wywiad rodzinny jest najważniejszym niezależnym czynnikiem ryzyka.63 Podatność na miażdżycę ma znaczący komponent genetyczny, dlatego ważne jest poinformowanie lekarza o rodzinnej historii miażdżycy.64

Podsumowanie etiologii miażdżycy

Miażdżyca to choroba o złożonej etiologii, która rozwija się przez wiele lat. Uszkodzenie śródbłonka naczyniowego stanowi początkowy etap choroby, po którym następuje kaskada zdarzeń prowadzących do powstawania blaszki miażdżycowej.6566

Czynniki przyczyniające się do tego uszkodzenia obejmują dyslipidemię, nadciśnienie, palenie tytoniu, cukrzycę, otyłość, brak aktywności fizycznej, stany zapalne i predyspozycje genetyczne.167 W miarę postępu choroby, blaszki miażdżycowe mogą zwężać tętnice, prowadząc do niedokrwienia tkanek, lub mogą pęknąć, powodując zakrzepy i poważne zdarzenia sercowo-naczyniowe.68

Zrozumienie etiologii i mechanizmów miażdżycy pozwala na wczesną interwencję i leczenie, aby zapobiec lub opóźnić postęp choroby i jej powikłania.6970

  • #4 Atherosclerosis – Wikipedia
    https://en.wikipedia.org/wiki/Atherosclerosis
    Atherosclerosis is a pattern of the disease arteriosclerosis, characterized by development of abnormalities called lesions in walls of arteries. This is a chronic inflammatory disease involving many different cell types and is driven by elevated levels of cholesterol in the blood. The exact cause of atherosclerosis is unknown and is proposed to be multifactorial. Risk factors include abnormal cholesterol levels, elevated levels of inflammatory biomarkers, high blood pressure, diabetes, smoking (both active and passive smoking), obesity, genetic factors, family history, lifestyle habits, and an unhealthy diet. Plaque is made up of fat, cholesterol, immune cells, calcium, and other substances found in the blood. The narrowing of arteries limits the flow of oxygen-rich blood to parts of the body.
  • #5 Atherosclerosis | Heart and Stroke Foundation
    https://www.heartandstroke.ca/heart-disease/conditions/atherosclerosis
    Atherosclerosis is a slow, progressive condition that may begin as early as childhood. Its causes are complicated and not completely understood, but atherosclerosis is thought to start when the inner lining of the artery becomes damaged. The damage can be caused by: […] The blood vessel wall reacts to this injury by depositing a plaque made up of fatty substances, cholesterol, calcium and other substances on the inner lining of the artery. Gradually, the blood vessels narrow, making it harder for blood to flow.
  • #6 Arteriosclerosis / atherosclerosis | Beacon Health System

    https://www.nhlbi.nih.gov/health/atherosclerosis/causes
    Risk factors are conditions or habits that make a person more likely to develop a disease. Nearly half of Americans have high blood pressure or unhealthy cholesterol levels, or they smoke. These are key risk factors that can trigger the start of plaque buildup. […] What causes atherosclerosis? Plaque buildup in the arteries starts with damage to the arteries. Risk factors such as unhealthy lifestyle habits, medical conditions, or your genes can cause this damage. […] Some atherosclerosis risk factors can trigger the buildup of plaque in your arteries. Other risk factors can lead to an increase in your blood pressure or cholesterol levels. The more risk factors you have, the higher your risk of complications, including heart attack and stroke, or even disability or death. […] Some common examples of risk factors for atherosclerosis are: Diabetes: High blood sugar can damage the inner layers of the arteries, causing plaque buildup. Family history: Your genes may raise your risk, especially if you have a common inherited cholesterol disorder called familial hypercholesterolemia. This condition affects about 1 in 300 people. High blood pressure: Over time, high blood pressure can damage artery walls, allowing plaque to build up. In the United States, high blood pressure accounts for more deaths linked to atherosclerosis than any other risk factor that you can change. Inflammatory diseases: When you have a condition such as rheumatoid arthritis or psoriasis, high levels of inflammation can injure your blood vessels, which can lead to plaque buildup. Lack of physical activity: Spending little time moving each day while spending a lot of time in front of screens is linked to unhealthy cholesterol levels that lead to atherosclerosis. Older age: For most people, plaque buildup starts in childhood and gets worse as they get older. In men, the risk increases after age 45. In women, the risk increases after age 55. The risk is even higher for women who have endometriosis or polycystic ovary syndrome, or if they had gestational diabetes or preeclampsia during a pregnancy. Overweight or obesity: Overweight and obesity raise the risk for heart disease and are linked to many other health problems, including type 2 diabetes and cancer. Nearly 3 in 4 adults ages 20 or older in the United States are either overweight or have obesity. Nearly 1 in 5 children and teens ages 2 to 19 have obesity. Race: Black Americans’ risk of death from heart disease is 30% higher than White Americans’ risk. People of South Asian origin (Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka) also have a higher heart disease risk. Smoking and secondhand smoke: Almost one-third of deaths caused by coronary heart disease are linked to smoking or exposure to secondhand smoke. Secondhand smoke can cause atherosclerosis-linked disease and stroke. Unhealthy diet: Eating a lot of foods high in fat especially saturated fat can increase your cholesterol levels. Saturated fats are found in meat and dairy products (except nonfat dairy). Also, drinking too much alcohol or binge drinking can raise your total cholesterol level.

    Atherosclerosis can put blood flow at risk as your arteries become blocked, and it can cause clots to form. […] Doctors don’t know exactly how atherosclerosis starts. But it’s believed to begin when the endothelium, the thin layer of cells that lines your arteries, somehow gets damaged. It’s a progressive disease that can begin in childhood. […] Common causes of damage to the endothelium include: High cholesterol, High blood pressure, Inflammation, like from arthritis or lupus, Obesity or diabetes, Smoking. […] Atherosclerosis usually doesn’t cause symptoms until you’re middle-aged or older. […] The following can increase your risk of atherosclerosis. These risk factors are behind more than 90% of all heart attacks: Abdominal obesity („spare tire”), Diabetes and insulin resistance, Family history of heart disease, High alcohol intake (more than one to two drinks a day, depending on your size), High blood pressure, High LDL cholesterol, High levels of C-reactive protein (CRP) in your blood, which is a signal of inflammation, High triglycerides, Not eating fruits and vegetables, Not exercising regularly, Sleep apnea, Smoking, Stress.
  • #14 Atherosclerosis – Cardiovascular Disorders – Merck Manual Professional Edition
    https://www.merckmanuals.com/professional/cardiovascular-disorders/arteriosclerosis/atherosclerosis
    There are numerous risk factors for atherosclerosis. Certain factors tend to cluster as the metabolic syndrome. This syndrome includes abdominal obesity, atherogenic dyslipidemia, hypertension, insulin resistance, a prothrombotic state, and a proinflammatory state in sedentary patients. Insulin resistance is not synonymous with the metabolic syndrome but may be key in its etiology. […] Dyslipidemia (high total, high LDL, or low high-density lipoprotein [HDL] cholesterol), hypertension, and diabetes promote atherosclerosis by amplifying or augmenting endothelial dysfunction and inflammatory pathways in vascular endothelium. […] Hypertension may lead to vascular inflammation via angiotensin II-mediated mechanisms. […] Diabetes leads to the formation of advanced glycation end products, which increase the production of proinflammatory cytokines from endothelial cells.

    Plaque buildup, or fatty deposits, in your arteries is called atherosclerosis. These deposits are made up of cholesterol, fatty substances, cellular waste products, calcium and fibrin, a clotting material in the blood. Atherosclerosis is a type of arteriosclerosis. Arteriosclerosis means hardening of the arteries. […] Many scientists believe plaque begins when an artery’s inner lining becomes damaged. Four possible causes of such damage are: Elevated levels of cholesterol and triglycerides in the blood, High blood pressure, Tobacco smoking, such as cigarettes, Diabetes. […] Smoking plays a big role in the progression of atherosclerosis in the aorta (the body’s main artery), coronary arteries and arteries in the legs. Smoking makes fatty deposits more likely to form, and it speeds up the growth of plaque.

    Risk factors are conditions or habits that make a person more likely to develop a disease. Nearly half of Americans have high blood pressure or unhealthy cholesterol levels, or they smoke. These are key risk factors that can trigger the start of plaque buildup. […] What causes atherosclerosis? Plaque buildup in the arteries starts with damage to the arteries. Risk factors such as unhealthy lifestyle habits, medical conditions, or your genes can cause this damage. […] Some atherosclerosis risk factors can trigger the buildup of plaque in your arteries. Other risk factors can lead to an increase in your blood pressure or cholesterol levels. The more risk factors you have, the higher your risk of complications, including heart attack and stroke, or even disability or death. […] Some common examples of risk factors for atherosclerosis are: Diabetes: High blood sugar can damage the inner layers of the arteries, causing plaque buildup. Family history: Your genes may raise your risk, especially if you have a common inherited cholesterol disorder called familial hypercholesterolemia. This condition affects about 1 in 300 people. High blood pressure: Over time, high blood pressure can damage artery walls, allowing plaque to build up. In the United States, high blood pressure accounts for more deaths linked to atherosclerosis than any other risk factor that you can change. Inflammatory diseases: When you have a condition such as rheumatoid arthritis or psoriasis, high levels of inflammation can injure your blood vessels, which can lead to plaque buildup. Lack of physical activity: Spending little time moving each day while spending a lot of time in front of screens is linked to unhealthy cholesterol levels that lead to atherosclerosis. Older age: For most people, plaque buildup starts in childhood and gets worse as they get older. In men, the risk increases after age 45. In women, the risk increases after age 55. The risk is even higher for women who have endometriosis or polycystic ovary syndrome, or if they had gestational diabetes or preeclampsia during a pregnancy. Overweight or obesity: Overweight and obesity raise the risk for heart disease and are linked to many other health problems, including type 2 diabetes and cancer. Nearly 3 in 4 adults ages 20 or older in the United States are either overweight or have obesity. Nearly 1 in 5 children and teens ages 2 to 19 have obesity. Race: Black Americans’ risk of death from heart disease is 30% higher than White Americans’ risk. People of South Asian origin (Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka) also have a higher heart disease risk. Smoking and secondhand smoke: Almost one-third of deaths caused by coronary heart disease are linked to smoking or exposure to secondhand smoke. Secondhand smoke can cause atherosclerosis-linked disease and stroke. Unhealthy diet: Eating a lot of foods high in fat especially saturated fat can increase your cholesterol levels. Saturated fats are found in meat and dairy products (except nonfat dairy). Also, drinking too much alcohol or binge drinking can raise your total cholesterol level.

    https://www.medicalnewstoday.com/articles/247837
    Atherosclerosis happens when arteries become narrow and hard due to a buildup of plaque around the artery wall. […] The plaque that is the cause of atherosclerosis consists of cholesterol, calcium, fat, and other substances, and it can harder over time. […] Smoking, high blood pressure and other factors increase the risk of developing the condition. […] Atherosclerosis happens when the endothelium becomes damaged, due to factors such as smoking, high blood pressure, or high levels of glucose, fat, and cholesterol in the blood. […] This damage allows a collection of substances, known as plaque, to build up in the artery wall. […] A clot can block the artery, leading to life threatening complications, such as stroke and heart attack. […] People with a higher risk of atherosclerosis include those with diabetes or insulin resistance, a family history of cardiovascular disease, a history of tobacco smoking, high levels of low-density lipoprotein (LDL), or bad cholesterol, low physical activity levels, older age, a diet high in saturated fat, trans fat, cholesterol, salt, and sugar, high blood pressure, obesity, high levels of triglycerides in the blood, stress, high alcohol intake, and sleep apnea.

    Risk factors are conditions or habits that make a person more likely to develop a disease. Nearly half of Americans have high blood pressure or unhealthy cholesterol levels, or they smoke. These are key risk factors that can trigger the start of plaque buildup. […] What causes atherosclerosis? Plaque buildup in the arteries starts with damage to the arteries. Risk factors such as unhealthy lifestyle habits, medical conditions, or your genes can cause this damage. […] Some atherosclerosis risk factors can trigger the buildup of plaque in your arteries. Other risk factors can lead to an increase in your blood pressure or cholesterol levels. The more risk factors you have, the higher your risk of complications, including heart attack and stroke, or even disability or death. […] Some common examples of risk factors for atherosclerosis are: Diabetes: High blood sugar can damage the inner layers of the arteries, causing plaque buildup. Family history: Your genes may raise your risk, especially if you have a common inherited cholesterol disorder called familial hypercholesterolemia. This condition affects about 1 in 300 people. High blood pressure: Over time, high blood pressure can damage artery walls, allowing plaque to build up. In the United States, high blood pressure accounts for more deaths linked to atherosclerosis than any other risk factor that you can change. Inflammatory diseases: When you have a condition such as rheumatoid arthritis or psoriasis, high levels of inflammation can injure your blood vessels, which can lead to plaque buildup. Lack of physical activity: Spending little time moving each day while spending a lot of time in front of screens is linked to unhealthy cholesterol levels that lead to atherosclerosis. Older age: For most people, plaque buildup starts in childhood and gets worse as they get older. In men, the risk increases after age 45. In women, the risk increases after age 55. The risk is even higher for women who have endometriosis or polycystic ovary syndrome, or if they had gestational diabetes or preeclampsia during a pregnancy. Overweight or obesity: Overweight and obesity raise the risk for heart disease and are linked to many other health problems, including type 2 diabetes and cancer. Nearly 3 in 4 adults ages 20 or older in the United States are either overweight or have obesity. Nearly 1 in 5 children and teens ages 2 to 19 have obesity. Race: Black Americans’ risk of death from heart disease is 30% higher than White Americans’ risk. People of South Asian origin (Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka) also have a higher heart disease risk. Smoking and secondhand smoke: Almost one-third of deaths caused by coronary heart disease are linked to smoking or exposure to secondhand smoke. Secondhand smoke can cause atherosclerosis-linked disease and stroke. Unhealthy diet: Eating a lot of foods high in fat especially saturated fat can increase your cholesterol levels. Saturated fats are found in meat and dairy products (except nonfat dairy). Also, drinking too much alcohol or binge drinking can raise your total cholesterol level.

    The vascular endothelium is a heterogeneous monolayer formed by endothelial cells (ECs), which face the luminal side of all blood vessels, representing the first barrier for molecules, cells, or pathogens circulating in the bloodstream. […] The extensive correlative data indicating that low shear or disrupted flow accounts for the localization of atherosclerosis lesions emphasize the importance of arterial branches and bifurcations when performing a diagnosis of atherosclerotic lesion development or progression. […] Endothelial dysfunction is also explained through a reduction in NO bioavailability. NO is synthesized from L-arginine in ECs in a reaction catalyzed by eNOS and diffuses across cell membranes, reaching the smooth muscle tissue of the artery wall. NO promotes smooth muscle fiber relaxation, known as endothelium-dependent vasodilatation, and is considered an athero-protective molecule, because it counteracts atherogenesis and its complications.

    Disruption of the mechanisms involved in vascular homeostasis regulation leads to endothelial dysfunction. Briefly, when ECs lose their ability to maintain homeostasis, vessel walls are predisposed to vasoconstriction, lipid infiltration, leukocyte adhesion, platelet activation, and oxidative stress, among other things. Together, these induce an inflammatory response that is considered the first step of atheromatous plaque formation: the fatty streak. […] Hemodynamic forces constitute a local risk factor of atherogenesis, as they promote endothelial dysfunction. […] Atherosclerosis is a disease that is characterized by the accumulation of lipids, fibrous elements, and calcification within the large arteries.
