Exercise is certainly beneficial to patients with coronary heart disease, but improper exercise, to patients with coronary heart disease to bring harm is not uncommon. Therefore, patients with coronary heart disease in participating in sports, must pay attention to the following issues: 1, exercise before to avoid emotional excitement. Nervousness, emotional excitement can make the blood catecholamine increase, reduce the threshold of ventricular fibrillation, coupled with the exercise can be induced ventricular fibrillation risk, therefore, for angina attack within three days, and myocardial infarction within six months after the patient, should not be done to do this more strenuous exercise. 2, should not eat before exercise. Because after eating the body’s blood supply needs new distribution, flow to the stomach and intestines to help digest the increase in the amount of blood, while the heart blood supply is relatively reduced, easy to cause the relative insufficiency of coronary artery blood supply, thus angina pectoris. 3, exercise should be gradual, persistent, usually do not exercise, should be measured, in order not to induce symptoms as the premise, gradually extend the exercise time and intensity, do not suddenly engage in strenuous exercise. 4, exercise should avoid wearing too thick, affecting heat dissipation, increase heart rate. Increased heart rate will increase myocardial oxygen consumption. 5, avoid taking a hot bath immediately after exercise. Because the whole body immersed in hot water, is bound to cause extensive vasodilatation, so that the blood supply to the heart is relatively reduced. 6, avoid smoking after exercise. Some people often smoke as a kind of rest after exercise, which is very harmful. Because the heart after exercise there is a post-exercise vulnerable period, smoking is easy to make the blood free fatty acids and the release of catecholamines, coupled with the role of nicotine and easy to induce cardiac accidents. 7, coronary heart disease patients in physical exercise, it is best to avoid early morning heart attack “peak period”, arranged in the afternoon and dinner after half an hour to 1 hour for good.
