Strenuous exercise heart pain is often due to myocardial ischemia, the most common cause of myocardial ischemia is coronary heart disease, which is a heart disease caused by long-term atherosclerosis of the coronary arteries leading to narrowing of the coronary vessels, or even occlusion, and ischemia and hypoxia of the myocardial cells. Patients with coronary heart disease can include angina pectoris, myocardial infarction and many other types. The basic cause is coronary atherosclerosis, which also includes factors such as coronary artery myocardial bridge and coronary artery spasm. In addition strenuous exercise, satiety, cold, and emotional stimulation are often triggers for the occurrence of myocardial ischemia. Strenuous exercise is often a very strong trigger for myocardial ischemia, which can lead to the occurrence of angina pectoris and myocardial infarction. Patients with angina pectoris last 1-5 minutes, up to 15 minutes, and for patients with myocardial infarction often last long, more than half an hour, and are accompanied by cold sweats, nausea, vomiting, lowered blood pressure, shock and other symptoms.
