Mild mitral and tricuspid regurgitation does not usually affect the life expectancy of patients and is not a cause for concern. In general, patients with mild mitral and tricuspid regurgitation who have no primary disease and no symptoms usually do not require treatment, and regular follow-up visits are sufficient and do not affect the patient’s life expectancy, which is the same as that of a normal person. If the patient has other primary diseases, such as rheumatic heart disease, degenerative heart valve disease, or dilated cardiomyopathy or ischemic cardiomyopathy, the heart may be enlarged, resulting in relative valve insufficiency and regurgitation. In this case, the patient should actively treat the primary disease and assess the cardiac function according to the cardiac EF value. After comprehensive judgment, medications can be used first to improve cardiac function, reverse ventricular remodeling, prevent the occurrence of heart failure, and perform valve repair, balloon angioplasty, or valve replacement surgery if necessary. After aggressive treatment of the primary disease, the patient can fully recover and survive for a long time if there are no other complications. Such patients are advised to avoid infections, have a low-salt, low-fat, balanced diet, eat more vegetables and fruits, eat more foods containing unsaturated fatty acids, quit smoking and alcohol, avoid overeating, and work and rest regularly.
