Some people think that once the coronary heart disease, only rest and recuperation, should not exercise, in fact, this is not correct, for patients with coronary heart disease, appropriate participation in aerobic exercise, not only will not aggravate the coronary heart disease, but also conducive to the recovery of patients with coronary heart disease. Coronary heart disease patients should pay attention to the following points: ① Avoid emotional excitement and nervousness before and after exercise: because it can increase the level of catecholamines, inducing arrhythmias and myocardial ischemia. ② Exercise should not be full before: after a full meal, the heart load increases, the human blood supply redistribution, so that the visceral blood flow increases, while the heart blood supply is relatively reduced, thus causing insufficient coronary blood supply. ③ exercise should be gradual, persistent, step by step. ④Physical activity should pay attention to the season, climate and temperature changes: winter and spring are the peak of coronary heart disease and myocardial infarction, so pay attention to avoid cold stimulation. ⑤ Physical activity should be carried out after ten o’clock in the morning, especially in the cold season, avoiding too cold and too hot environment. ⑥Do not take cold bath or sauna after physical activity, especially for patients with myocardial infarction.
