Myocardial infarction is a more serious disease of the heart. Suffering from myocardial infarction can cause significant harm to the body and, in severe cases, can be life-threatening. If not properly treated, it can lead to various complications. The most common complications include arrhythmias, heart failure, cardiogenic shock, rupture of the ventricular wall, papillary muscle rupture, and ventricular septal perforation. Therefore, once a myocardial infarction occurs, it is crucial to actively perform rescue operations and treatments to prevent the occurrence of these complications.
