Whether or not a heart murmur requires treatment is mainly determined by the type and cause of the murmur. Physiological murmurs are generally untreatable, while heart diseases require medication or surgery. The severity of heart murmurs can be clinically categorized into 6 levels, of which level 1 to 2 murmurs are mostly physiological murmurs, which can be treated without special treatment, and can be reviewed regularly. For murmurs of grade 3 and above, they are considered to be pathologic murmurs caused by changes in the organic structure of the heart, such as valvular stenosis or closure insufficiency, perforation of the ventricular septum after an acute infarction, mitral valve prolapse, etc. If the condition is mild, medication can be used to treat it. If the condition is mild, drug treatment can be chosen, such as oral nitroglycerin and other drugs to help improve blood circulation, oral spironolactone, metoprolol and other drugs to improve ventricular remodeling. For severe conditions, surgical treatments, such as valve replacement surgery, valve repair surgery, interventional surgery, etc., can be considered according to the cause of the disease. When heart murmur occurs, the cause of the disease should be identified under the guidance of the physician, choose the appropriate treatment, and actively cooperate with the treatment.
