Heart failure is not mandatory after anterior wall myocardial infarction, occurring in about 32% to 48% of cases.
Anterior wall myocardial infarction mainly causes acute left heart failure, which may occur within the first few days of illness or during the improvement phase of pain and shock, and is caused by a significant reduction or incoordination of post-infarction cardiac diastolic force. Patients may experience dyspnea cough, cyanosis irritability, and in severe cases pulmonary edema, followed by manifestations of right heart failure.
If thrombolysis or percutaneous coronary intervention is performed within 12 hours of the occurrence of acute myocardial infarction, so that the occluded coronary arteries are reopened and the myocardium is reperfused, it is possible to save the dying myocardium or reduce the scope of infarction, and the earlier the better, the smaller the damage is, and the likelihood of heart failure is reduced accordingly.
According to the presence or absence of heart failure and the corresponding severity of hemodynamic changes, the degree of heart failure caused by acute myocardial infarction can be divided into four levels according to the Killip grading method. The higher the grade, the more serious the disease and the worse the prognosis. If you feel unwell, you should consult a doctor promptly.
