Under what circumstances should a heart stent be placed?

Acute myocardial infarction (AMI) is the necrosis of myocardial tissue caused by complete obstruction of coronary arteries. Patients need to restore coronary artery patency through cardiac stents to reduce myocardial damage. 2. Stable angina pectoris Stable angina pectoris is myocardial ischemia caused by coronary artery stenosis. If the condition is serious, it is necessary to place cardiac stents in time to improve myocardial blood supply. 3. Coronary atherosclerotic heart disease Coronary atherosclerotic heart disease is insufficient blood supply to the heart caused by coronary artery stenosis or obstruction. At this time, cardiac stents are also needed to restore blood supply.
