How long a patient with cardiac hypertrophy can live depends on the severity of the disease, whether there is outflow tract obstruction, and whether the patient is actively treated. If the degree of myocardial hypertrophy is relatively mild and there are no other complications, active treatment will not affect life expectancy. If the degree of myocardial hypertrophy is more serious and there is outflow tract obstruction, coupled with the lack of timely treatment, it will have a certain impact on the life expectancy, and may even lead to sudden death in the case of strenuous exercise, emotional excitement and so on. For myocardial hypertrophy is more serious, accompanied by chest tightness, chest pain, palpitations, dyspnea and other symptoms, and even also complicate the arrhythmia, heart failure, the survival time will be shorter, may be only a few years, if the development of the disease to the advanced stage, at any time there will be a danger to life. Myocardial hypertrophy progresses slowly, and the overall prognosis is not bad. Patients with myocardial hypertrophy, after the onset of the disease, must consult a doctor for examination in a timely manner, and actively and rigorously cooperate with the doctor’s treatment, in order to prolong the survival time and improve the quality of life.
