Myocardial infarction at the age of about 40 years, after the operation, usually can survive for a long time, but exactly how long can live varies from person to person. Myocardial infarction is a relatively serious disease, and the main pathogenesis is ischemic necrosis of myocardial cells due to thrombus in the coronary arteries of the heart, blocking the blood vessels. If timely measures can be taken after myocardial infarction occurs, through interventional therapy or related thrombolytic therapy, patients can survive for many years. However, if the myocardial infarction is large or not treated in time, and significant cardiac remodeling occurs, even if surgery is performed, the results may be poor, and more obvious cardiac complications such as heart failure, arrhythmia, ventricular septal perforation, and cardiac rupture may occur, and in severe cases, may even be life-threatening. Postoperative medication, regular checkups, control of risk factors, smoking and alcohol cessation are needed to slow down the progression of the disease and increase life expectancy.
