Causes of myocardial infarction

I believe many people have heard of myocardial infarction in their lives. This is a common complication, most of which are caused by certain reasons. The occurrence of myocardial infarction may be mostly related to physical overwork, and it is not ruled out that it is caused by overeating, constipation, long-term smoking and excessive drinking. Therefore, you must slowly adjust it in daily life and choose the appropriate method to promote the body's repair.

Pathological etiology

Most patients have coronary atherosclerosis and stenosis. Due to certain factors, the coronary atherosclerotic plaques rupture, and the platelets in the blood gather on the surface of the ruptured plaques to form blood clots (thrombi), which suddenly block the coronary artery lumen and cause myocardial ischemia and necrosis. In addition, a sharp increase in myocardial oxygen consumption or coronary artery spasm can also induce acute myocardial infarction. Common causes are as follows:

Overwork (30%)

Excessive physical labor, especially climbing stairs with heavy loads, excessive physical activity, continuous stress and fatigue, etc., can increase the burden on the heart and suddenly increase the myocardial oxygen demand. The coronary arteries of patients with coronary heart disease have become hardened and narrowed and cannot fully expand, causing myocardial ischemia. Severe physical stress can also induce plaque rupture and lead to acute myocardial infarction.

Overeating (15%)

Many cases of myocardial infarction occur after overeating. After eating a large amount of high-fat, high-calorie food, blood lipid concentration suddenly increases, leading to increased blood viscosity and increased platelet aggregation. Thrombosis forms on the basis of coronary artery stenosis, causing acute myocardial infarction.

Constipation (13%)

Constipation is very common among the elderly. Clinically, it is not uncommon for elderly people to suffer myocardial infarction due to holding their breath due to constipation. The elderly must pay enough attention to this and keep their bowel movements smooth.

Smoking and heavy drinking (10%)

Smoking and heavy drinking can induce acute myocardial infarction by inducing coronary artery spasm and increasing myocardial oxygen consumption.

Excitement (6%)

It is triggered by intense emotional changes such as excitement, tension, and anger.

Cold stimulation (5%)

Sudden cold stimulation may induce acute myocardial infarction. Therefore, patients with coronary heart disease should pay great attention to keeping warm. The cold seasons in winter and spring are one of the reasons for the high incidence of acute myocardial infarction.
