Inferior myocardial infarction is very serious. Inferior myocardial infarction is a type of acute myocardial infarction, which is prone to mechanical complications of acute myocardial infarction, such as heart rupture and septal perforation, and also prone to slowed heart rate and reduced blood pressure, which can cause cardiac arrest in severe cases, and may also cause malignant arrhythmias, ventricular tachycardia, and ventricular fibrillation, all of which can be life-threatening in severe cases. Once acute inferior wall myocardial infarction is diagnosed, oral aspirin, clopidogrel, and tigretol should be administered first for antiplatelet aggregation and oral statins for plaque stabilization. If the symptom onset has resolved within 12 hours, acute coronary angiography with stenting is still recommended. If the symptoms persist without remission, regardless of how long the symptoms have been present, an acute coronary angiogram with stent implantation should be performed, followed by long-term oral secondary prevention of coronary artery disease.
