Coronary heart disease and exercise contradictions Coronary heart disease patients with ischemic heart activity intensity is often directly proportional relationship. In other words, the increase in human activity, the need to step up the heart beat to meet the increased demand for systemic blood supply, which inevitably increased myocardial ischemia, which induced angina pectoris, myocardial infarction episodes. This is some sudden coronary heart disease in patients with chest tightness, shortness of breath or fainted or aggravated after exercise, admitted to the hospital. Originally lack of exercise may be
