Angina pectoris is the most common symptom of coronary heart disease. the clinical treatment strategy of angina pectoris is based on preventing the occurrence and development of angina pectoris. But in fact, the severity of myocardial infarction in patients with recurrent angina pectoris is lower, and the myocardial collateral circulation is abundant in patients with angina pectoris, which shows that angina pectoris or myocardial ischemia can promote the formation of collateral circulation and protect patients with coronary heart disease. Exercise can induce myocardial ischemia
many patients with coronary heart disease do not dare to exercise or doctors warn patients to avoid exercise. However, exercise may induce reversible myocardial ischemia, promote the formation of test branch circulation and increase the ability of myocardial self-protection.
Exercise increases the possibility of myocardial infarction
