In general, heart failure due to myocardial infarction cannot be fully restored to normal levels, and treatment is aimed at relieving symptoms and preventing further progression of the disease. The prognosis of heart failure caused by myocardial infarction is related to a number of factors, such as the size of the infarction, the creation of collateral circulation, and the timeliness of treatment. In the case of a large myocardial infarction where collateral circulation has not yet been established, the function of the heart is usually irreversible after the onset of heart failure. Patients may be treated with anti-heart failure therapy, including diuretics such as hydrochlorothiazide, RAAS inhibitors such as captopril, beta-receptor antagonists such as metoprolol tartrate, and positive inotropic agents such as digoxin. It is recommended that patients go to the hospital in time to receive standardized treatment under the guidance of professional doctors, and not self-medication.
