The enlarged heart muscle is medically understood to be an enlarged heart. The number of years a patient can live is mainly related to the cause and treatment, and should be analyzed in a specific way, not in a general way. Patients with an enlarged heart tend to have a shorter life expectancy due to thinning of the heart muscle, reduced contractility, and decreased ejection fraction, with severe cases living no more than 5 years. If the patient has an enlarged heart due to mild to moderate heart failure, the basic life expectancy can exceed 5-10 years after diagnosis, but the patient needs to adhere to medical advice to take Yashida to reverse ventricular remodeling, betalactone to reduce the number of heartbeats and reduce the burden on the heart, and spironolactone to inhibit RAS system therapy. If a patient has an enlarged heart due to severe heart failure, despite adherence to medications, cardiac function will gradually decline and he or she can eventually die from malignant arrhythmias with a poor prognosis. In short, the specific survival period varies from person to person and there is no specific time point. Therefore, patients with an enlarged heart are advised to visit the cardiology department of a regular hospital in a timely manner, so that the specific cause of the disease can be clarified after examination by a professional doctor, and drugs and other intervention methods can be applied to control the related symptoms and complications.
