What are the causes of myocardial infarction?

Generally, myocardial infarction may be caused by factors such as aging, excessive fatigue, hyperlipidemia, hypertension, diabetes, and others. If you experience any discomfort, please seek medical attention promptly and undergo symptomatic treatment under the guidance of a qualified physician. Detailed explanations are as follows:

1. Aging

With increasing age, blood vessels gradually age, lose elasticity, and become thicker and stiffer. Coronary arteries are more likely to narrow or become blocked, leading to insufficient blood supply to the heart muscle and increasing the risk of myocardial infarction. It is recommended to undergo regular physical examinations and monitor cardiovascular health indicators such as blood pressure, lipid levels, and blood glucose to detect problems early and intervene promptly.

2. Excessive Fatigue

Long-term excessive fatigue places the body in a state of stress, stimulating the sympathetic nervous system and releasing hormones such as adrenaline, which increases heart rate and may impair the normal dilation and constriction function of coronary arteries, causing coronary artery spasms and reduced blood supply to the heart muscle, potentially triggering myocardial infarction. It is important to manage work and life reasonably, avoid prolonged continuous work, ensure adequate rest and sleep, learn to relax appropriately, and relieve stress.

3. Hyperlipidemia

Hyperlipidemia mainly results from long-term consumption of high-fat, high-cholesterol foods, lack of physical activity, and genetic factors that cause lipid metabolism disorders, increasing lipid levels in the blood, especially low-density lipoprotein cholesterol (LDL-C), which may accelerate the progression of atherosclerosis, leading to the aforementioned conditions. It may also present symptoms such as limb numbness and loss of appetite. Treatment may include medications such as amlodipine atorvastatin calcium tablets, rosuvastatin calcium tablets, and probucol tablets, as advised by a physician.

4. Hypertension

Hypertension is primarily caused by multiple factors, including genetic predisposition, mental stress, and unhealthy dietary habits, which together lead to dysfunction in the body's blood pressure regulation mechanisms. It may cause vascular endothelial damage, promoting atherosclerosis and resulting in myocardial infarction. Symptoms may also include headache and dizziness. Patients may take medications such as amlodipine besylate tablets, losartan potassium tablets, and metoprolol tartrate tablets as directed by a physician.

5. Diabetes

Diabetes may be associated with genetic, dietary, and lifestyle factors. Elevated blood glucose levels may damage vascular endothelial cells, accelerating the progression of atherosclerosis, which may subsequently lead to myocardial infarction. Other symptoms may include increased thirst and frequent urination. Treatment options may include medications such as metformin hydrochloride tablets, glipizide tablets, and insulin aspart injection, as directed by a physician.

In daily life, it is important to maintain emotional stability, avoid intense emotional fluctuations, and avoid prolonged exposure to cold environments to reduce the risk of myocardial infarction.
