Myocardial infarction is a relatively serious cardiovascular system disease, and the recurrence rate is about 10-30%. Clinically, there are many factors affecting the recurrence rate of myocardial infarction, such as the treatment of myocardial infarction, the implementation of secondary preventive measures, and the condition of one’s own underlying disease, and other factors. After a heart attack, the internal environment, plaque, and different parts of the plaque can be insufficiently stabilized, so the recurrence rate is high. Heart attack requires taking medications on time, such as antiplatelet drugs. At the same time, strict management of blood glucose, blood lipids, blood pressure and other basic indicators. After myocardial infarction, you need to receive a full range of examination and diagnosis by a professional physician, and follow the doctor’s instructions to take medication on time in order to prevent recurrent episodes of myocardial infarction.
