Causes of Myocardial Infarction

Myocardial infarction is a very common disease nowadays, and the incidence rate is constantly increasing. Generally, myocardial infarction is acute, and once it occurs, it will be very serious. Many people fail to take timely measures, which will cause great harm. Death due to acute myocardial infarction is also very common. Everyone should understand the causes of myocardial infarction and take precautions.

If we know the cause of myocardial infarction, we can better prevent the occurrence of this disease. Many times when myocardial infarction occurs, we don’t know what is going on and don’t take correct treatment measures, and the patient is seriously harmed.

Causes

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:

1. Overwork

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.

2. Excitement

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

3. Overeating

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.

4. Cold stimulation

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.

5. Constipation

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.

6. Smoking and drinking heavily

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

Everyone should know the causes of myocardial infarction. If symptoms of myocardial infarction appear, you must take them seriously. The most important thing is to stay in bed first and don't be too nervous. Go to the hospital for treatment in time after the symptoms are relieved. In normal times, you should learn more about myocardial infarction to avoid serious harm to your body.
