Mild myocardial ischemia can run, but according to their own heart function to develop a suitable mode of exercise and exercise time, severe myocardial ischemia patients should avoid running. Myocardial ischemia is not a contraindication to exercise. Appropriate exercise can increase the reserve function of the heart, which plays an important role in maintaining and sustaining cardiac function. However, for patients with myocardial ischemia, attention should be paid to evaluating cardiac function, understanding the severity of ischemia, and developing a scientific and reasonable exercise program. Patients with severe myocardial ischemia should avoid running, which may increase the load on the heart, aggravate myocardial ischemia, or even induce the occurrence of acute myocardial infarction. Patients with relatively mild disease can choose most of the exercise programs, but be careful to avoid strenuous exercise. Patients with severe myocardial ischemia should perform light exercise, such as walking and jogging. Patients with myocardial ischemia should formulate a scientific exercise prescription under the guidance of a doctor, choose the appropriate exercise and set a reasonable exercise time.
