Myocardial ischemia is divided into acute myocardial ischemia and chronic myocardial ischemia. For acute myocardial ischemia, it is not appropriate to use exercise to relieve symptoms or to enhance resistance and immunity. For chronic myocardial ischemia, aerobic exercise can be used, such as slow walking, swimming, jogging, etc. Avoid weight-bearing exercise, such as lifting a bar, etc. In addition, for the intensity of exercise, it is recommended that the amount of moderate intensity exercise should be above 150 minutes per week, and it is recommended that 30 minutes of exercise can be performed every day, which can enhance the tolerance of the myocardium. The etiology of myocardial ischemia should also be clarified, because myocardial ischemia can be caused by a variety of reasons. For myocardial ischemia caused by organic coronary artery disease, it is more important to perform coronary intervention or coronary artery bypass surgery, if necessary, in addition to medication.
