Coronary heart disease is due to the narrowing or occlusion of coronary arteries, resulting in myocardial ischemia and hypoxia or necrosis. Strenuous exercise may increase myocardial oxygen consumption, thus aggravating coronary heart disease, coronary heart disease patients can do some easy and soothing exercises to strengthen the body, the following three common exercises: 1, walking: belongs to a low degree, low energy consumption of exercise. It is suitable for patients with severe coronary heart disease. 2. Jogging: It is an aerobic exercise, slightly more than walking, but does not excessively increase myocardial oxygen consumption, improves collateral circulation and cardiopulmonary function, and is suitable for patients with mild coronary heart disease. 3. Ba Duan Jin: As a traditional aerobic exercise in Chinese medicine, it can be applied in the rehabilitation of coronary heart disease. Some studies have shown that adhering to a period of Baduanjin exercise, the level of malondialdehyde in the body will be reduced, the level of nitric oxide and the activity of superoxide dismutase will be increased, leading to a reduction in the degree of lipid peroxidation in the body, thus helping to resist atherosclerosis and reduce the incidence of coronary heart disease. In addition, like tai chi, yoga, stretching activities, etc., are also more suitable for patients with coronary heart disease exercise. It is important to note that patients with coronary heart disease need to warm up fully before exercise, but the action should not be too strenuous. If chest tightness or chest pain occurs during the exercise, stop the activity immediately and seek medical attention if necessary. Scientific and standardized exercise for patients with coronary artery disease can help improve heart function and quality of life.
