Exercise is certainly beneficial to patients with coronary heart disease, but improper exercise, to patients with coronary heart disease to bring harm has been altered. Coronary heart disease patients in sports, must pay attention to the following issues: 1, before and after the exercise 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, myocardial infarction after six months of the patient, should not do a more strenuous exercise. 2, should not be full before exercise: because after eating the body blood supply needs to be redistributed, flow to the gastrointestinal to help digestion of blood increased, while the heart blood supply is relatively reduced, easy to cause the relative blood supply of coronary artery insufficient, thus angina pectoris occurs. 3, exercise should be gradual: persistent, usually do not exercise, do not suddenly engage in strenuous exercise. 4, exercise should avoid wearing too thick: the impact of heat dissipation, increase heart rate, heart rate increases will make the myocardial oxygen consumption increase. 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.
