Some patients after myocardial infarction can survive up to 20 years, but the exact survival time is related to the severity of the disease. Acute myocardial infarction is a very serious cardiovascular disease, the blockage of blood vessels will lead to myocardial necrosis, during the onset of patients with the risk of sudden death, some patients timely and active treatment, there may also be severe heart failure, the survival time will be significantly shortened. With the gradual progress of medical technology, many regions can carry out emergency stent implantation or thrombolytic therapy, which can open the blood vessels at the early stage of the onset of the disease and save most of the myocardium, and the level of acute myocardial infarction has been significantly improved, and some patients can survive for more than 20 years.
