Is myocardial infarction caused by heart disease

summary

Myocardial infarction is mainly in the case of persistent hypoxia ischemia, myocardial necrosis, can be complicated with serious complications, endangering the lives of patients. Let's see if myocardial infarction is caused by heart disease.

Is myocardial infarction caused by heart disease

First of all, acute myocardial infarction is myocardial necrosis caused by acute and persistent ischemia and hypoxia of coronary artery. Patients often occur on the basis of coronary atherosclerotic stenosis. Due to some inducements, the coronary atherosclerotic plaque ruptures. Platelets in the blood gather on the surface of the ruptured plaque, forming blood clots (thrombus), suddenly blocking the coronary artery lumen, leading to myocardial ischemia and necrosis. Myocardial infarction is not caused by heart disease.

Secondly, excessive physical labor, especially climbing stairs with heavy load, excessive physical activity, continuous tension and fatigue, can aggravate the burden on the heart and increase the myocardial oxygen demand suddenly. However, the coronary artery of patients with coronary heart disease has been hardened and stenosed, which can not fully expand and cause myocardial ischemia. Severe physical load can also induce plaque rupture, leading to acute myocardial infarction.

Finally, smoking and heavy drinking can induce acute myocardial infarction by inducing coronary artery spasm and increasing myocardial oxygen consumption. Therefore, it is best to give up smoking and drinking.

matters needing attention

Live a happy life and be calm about everything. Don't take a bath when you're full or hungry. The temperature of the bath water should be similar to the body temperature. If the coronary heart disease is serious, the bath should be completed with the help of others.
