Causes of heart attack

Myocardial infarction is mainly caused by coronary atherosclerosis. In addition, thrombosis, vasospasm and other factors can also increase the risk of myocardial infarction. Myocardial infarction is a serious disease caused by myocardial ischemia, hypoxia or necrosis caused by coronary atherosclerosis. The following is a detailed analysis of the causes of myocardial infarction: 1. Coronary atherosclerosis Coronary atherosclerosis is the main cause of myocardial infarction. It is caused by cholesterol and other lipids in the blood accumulating in the walls of coronary arteries, forming plaques that cause narrowing and clogging of blood vessels. These plaques may rupture or form clots that further block blood vessels, leading to myocardial infarction.2. Thrombosis When a plaque ruptures or is damaged, platelets gather at the rupture site to form clots that completely or partially block blood vessels. Thrombosis is one of the most common causes of myocardial infarction. 3. Vasospasm Coronary artery spasm can also lead to myocardial infarction. Vasospasm can cause narrowing or occlusion of blood vessels, interrupting blood supply to the heart muscle. 4. Other factors In addition to the above causes, the following factors may also increase the risk of myocardial infarction: Chronic hypertension can damage vascular endothelial cells and promote the formation of atherosclerosis. Diabetes: Diabetic patients are prone to vascular disease, increasing the incidence of myocardial infarction. Hypercholesterolemia: Hypercholesterolemia, hyperglyceridemia and other lipid metabolism abnormalities are important risk factors for myocardial infarction. Smoking: Smoking can damage vascular endothelial cells, increase blood viscosity, leading to vascular stenosis. Lack of exercise: Lack of physical activity increases the risk of cardiovascular disease. Genetic factors: Certain gene mutations or familial diseases may increase the susceptibility to myocardial infarction. In summary, the causes of myocardial infarction are multi-faceted, including coronary atherosclerosis., thrombosis, vasospasm and other risk factors. Understanding these causes is important for preventing and treating myocardial infarction. For high-risk groups, such as hypertension, diabetes, hyperlipidemia patients, and smokers, corresponding preventive measures should be taken, such as controlling blood pressure, blood sugar, blood lipids, quitting smoking, appropriate exercise, etc., to reduce the risk of myocardial infarction.

If chest pain and other suspected myocardial infarction symptoms occur, seek medical attention immediately for timely diagnosis and treatment.
