If the patient’s inferior wall myocardial ischemia only shows myocardial ischemia on the electrocardiogram and the patient has no actual clinical symptoms, this condition is often not serious. If the patient’s inferior wall myocardial ischemia is manifested by ST-segment arch-back elevation, it is considered to be an acute inferior wall myocardial infarction, which is relatively serious. If the coronary CT shows only mild or moderate stenosis, the condition is often not serious. If there is severe stenosis in the coronary vessels, the condition is more serious and requires timely coronary intervention, installation of coronary stents and, if necessary, coronary artery bypass graft surgery. It is recommended that patients must actively take treatment in order to help prevent complications, because if there is severe stenosis, acute heart failure may occur at any time, and the condition is gradually more serious.
