Accomplished myocardial infarction generally cannot be restored to its original state, but it is possible to use medication to keep the heart function stable and not affect daily life. Obsolete myocardial infarction refers to myocardial infarction six months after acute myocardial infarction. Since myocardial cells are eternal cells that cannot be regenerated, the original infarcted myocardial cells will form scar, and these scars are unable to do the role of contraction of the heart, so the infarcted heart will have hemodynamic changes of diastolic and systolic dysfunction of the left heart, and the relative cardiac output and cardiac output will decrease, so the function will be relatively reduced compared with the previous one, which is an irreversible change, and therefore cannot be restored to the original condition. This is an irreversible change, so it is not possible to return to the original situation. This is an irreversible change and cannot be restored to the original situation. However, through active treatment, cardiac function can be maintained at a relatively stable level, without affecting normal life and life expectancy. At the same time, according to the doctor’s instruction, you can take aspirin or clopidogrel and other anti-platelet aggregation drugs, as well as statins such as atorvastatin to regulate blood lipids, beta-blockers to improve cardiac function and anti-arrhythmic drugs such as propranolol to prevent complications, but still need to be regularly followed up in order to avoid the heart to develop organisms and functional changes.
