Cardiac hypertrophy can be caused by hypertension, aortic stenosis, etc., or by hypertrophic cardiomyopathy. Generally, if the primary disease is controlled, the progression of myocardial hypertrophy will stop, and a good prognosis can be achieved with a long survival time. The prognosis is good and the survival time is long. The exact survival time varies greatly from person to person, but the prognosis is poor if heart failure occurs in the later stages of the disease.
Myocardial hypertrophy can lead to diastolic insufficiency of the heart, resulting in exertional dyspnea and, in severe cases, chest pain and fainting. It is usually caused by high blood pressure, aortic stenosis and other diseases. Myocardial hypertrophy will stop progressing once the primary disease is under control. However, if it develops into heart failure, the prognosis is poor and the patient’s life expectancy is seriously affected.
Hypertrophic cardiomyopathy can also cause myocardial hypertrophy, and the life expectancy of most patients is not very different from that of normal people. However, sudden death can occur if there is a relative who died suddenly, or if the person has a history of severe syncope, ventricular tachycardia, etc., and the ventricular wall hypertrophy is very severe.
There are other causes of cardiac hypertrophy, and it is advisable to seek prompt medical attention to identify the cause and treat it for the best prognosis.
