After what age won't have myocardial infarction

summary

Just last week, my father told me that his uncle had suffered from myocardial infarction and then let me go to the hospital to see him. Everyone knows that the incidence rate of myocardial infarction in the middle and old age population is very high. Therefore, we all need to know more about it. Let's talk about what age does not happen to have myocardial infarction.

After what age won't have myocardial infarction

First, acute myocardial infarction is myocardial necrosis caused by acute and persistent ischemia and hypoxia of coronary artery. Clinically, most patients have severe and persistent retrosternal pain, which can not be completely relieved by rest and nitrates, accompanied by increased serum myocardial enzyme activity and progressive ECG changes. They can be complicated with arrhythmia, shock or heart failure, and often life-threatening.

Second: patients often occur on the basis of coronary atherosclerotic stenosis. Due to some inducements, the coronary atherosclerotic plaque is ruptured. 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. In addition, acute myocardial infarction can also be induced by dramatic increase of myocardial oxygen consumption or coronary artery spasm Death.

Third: common inducements include overwork, excessive physical labor, especially climbing stairs with heavy load, excessive physical activity, continuous tension and fatigue, etc., which can aggravate the burden of 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.

matters needing attention

Therefore, compared with teenagers, myocardial infarction is more likely to occur in middle-aged and elderly people, because the physical fitness of middle-aged and elderly people begin to decline, and each index will fluctuate, so they will be more prone to suffer from this disease.
