Mild mitral tricuspid regurgitation can run, but care should be taken to avoid strenuous exercise. Mild mitral tricuspid regurgitation alone has a relatively small impact on cardiac function and rarely leads to cardiac insufficiency, but care should be taken to exclude organic heart disease. Patients can run normally, but should pay attention to the intensity of running and exercise time, avoid too strenuous exercise, so as not to affect the heart function. Mild mitral tricuspid regurgitation is relatively common in clinical practice, such as mild regurgitation of the valve in elderly patients due to calcification of the valve, and a small amount of regurgitation of the mitral tricuspid valve in normal people. Patients with mild mitral tricuspid regurgitation should pay attention to the ultrasound review to understand the dynamic changes of valve regurgitation, and pay attention to the exclusion of organic causes of valve regurgitation, to avoid the danger of other organic heart disease caused by exercise process. During exercise, if you have symptoms of chest tightness and shortness of breath, you should pay attention to reduce the amount of exercise, and try to develop an exercise program under the guidance of a physician.
