Introduction
Compared to inferior wall myocardial infarction, anterior wall myocardial infarction is more severe. The anterior myocardial region is rich in sympathetic nerves, and after infarction, these nerves are affected, making malignant arrhythmias such as ventricular fibrillation and ventricular tachycardia more likely to occur. If complications such as ventricular septal rupture or free wall rupture develop following an anterior wall myocardial infarction, the mortality rate exceeds 90%, often leading to sudden death in patients.
Generally, anterior wall myocardial infarction is more severe than inferior wall myocardial infarction. Both conditions are quite dangerous and require prompt treatment to prevent sudden death. Specific analysis is as follows:
The anterior wall of the heart has a relatively rich supply of sympathetic nerves. After infarction, these nerves may be affected, making malignant arrhythmias such as ventricular fibrillation and ventricular tachycardia more likely to occur. If complications such as ventricular septal rupture or free wall rupture develop following an anterior wall infarction, the mortality rate can exceed 90%, leading to sudden death in patients.
Immediate medical attention is necessary once a myocardial infarction occurs. Treatments may include balloon angioplasty and stent implantation. In daily life, it is important to avoid excessive physical exertion, maintain a nutritious diet, and promote stable disease management.
