The risk period after cardiac stenting is within two weeks of the procedure. Patients with coronary artery disease without myocardial infarction are at relatively low risk after the use of coronary interventional stenting procedures. Acute myocardial infarction, emergency coronary angiography, and stenting procedures carry a higher risk. The risk is generally greatest within one week after the procedure, with a predisposition to heart failure, malignant arrhythmias, cardiac rupture, ventricular wall tumor, cardiac tamponade, and post-myocardial infarction syndrome, but there is still a risk within a week or two. The risk is usually lower after two weeks, but there is still a risk of stent stenosis and narrowing of the rest of the vessels. It is necessary to control blood sugar, blood lipids, blood pressure, take antiplatelet therapy and plaque stabilization therapy to prevent recurrence of myocardial infarction. If there is any abnormality, you should go to the hospital for examination and treatment under the guidance of the doctor.
