Regular physical activity reduces the risk of coronary heart disease events. Studies on the incidence of different occupations have shown that sedentary professionals become a potential population with a high incidence of coronary heart disease, with a relative risk increase of 1.9 compared to active professionals. people who engage in moderate physical activity have a one-third lower mortality rate from coronary heart disease than those who are less active. Lack of physical activity is a very important independent risk factor for coronary heart disease, which can be modified by each patient and can play a role that drugs cannot. The incidence of coronary atherosclerosis is significantly higher in people with low physical activity. This may be due to the following reasons: less physical activity, weight gain, and easy lipid metabolism disorders; prolonged sedentary tend to cause endocrine disorders, elevated levels of catecholamines and corticosteroids, increased blood pressure, and coronary artery endothelial cell damage; prolonged sedentary can adversely affect the diastolic function of coronary arteries. Therefore, appropriate participation in sports can effectively lower blood sugar, reduce the “bad” cholesterol content and increase the “good” cholesterol content, which can effectively slow down the process of coronary atherosclerosis and reduce the risk of cardiovascular disease death. Lack of exercise is prone to coronary heart disease, but improper exercise can also trigger myocardial infarction. Approximately 4-5 out of every 100 myocardial infarction patients are exercise-induced. Sudden exercise death is one of the most serious cardiovascular hazards caused by inappropriate exercise in patients with coronary artery disease, mostly occurring in people who already have coronary artery disease that is not well controlled and who do not exercise under medical supervision. Warm tip: Before exercise, patients with coronary artery disease can undergo an exercise ECG test to assess the risk of secondary cardiovascular events, the degree of myocardial ischemia and the amount of exercise the patient can tolerate in order to develop a suitable exercise program. In addition, in addition to taking medication on time, patients with coronary artery disease need to pay special attention when exercising, avoiding exercise in bad weather; avoiding outbursts of exertion, going up and down steps; stopping exercise immediately for rest when feeling fatigue, chest pain, dizziness; and strictly adhering to the target heart rate and other exercise programs prescribed by the doctor.
