Left ventricular hypertrophy is not a separate disease in itself, but occurs as an intermediate process in some diseases or as a consequence of diseases, often as a risk factor for heart disease. In some athletes, the body requires more oxygen and more left ventricular ejection, which leads to physiological left ventricular hypertrophy. Pathological left ventricular hypertrophy is a compensatory adaptive response to the demands of the body, and many diseases result in compensatory hypertrophy of the heart. Left ventricular hypertrophy itself does not have many symptoms, and its main manifestations are some symptoms of the primary disease, but it can itself cause a series of diseases. If the degree of left ventricular hypertrophy is heavy, it can lead to insufficient blood supply to the heart muscle, and left ventricular hypertrophy can easily cause a decrease in the ejection function of the heart, which in turn can lead to a series of clinical manifestations, such as chest tightness and chest pain, poor breathing, and other symptoms, and can also easily lead to ischemia and hypoxia in the brain and other organs. If the etiology persists and worsens, it can lead to loss of compensation, which will eventually lead to left heart failure. In conclusion, left ventricular hypertrophy is difficult to correct and it is unlikely that it can return to normal. If significant hypertrophy occurs, it is still recommended to visit the cardiology department of a regular hospital for a clear diagnosis and, if necessary, treatment. In most cases, the cause is removed and the heart function can be normalized as long as it remains normal and the increased burden on the heart is avoided.
