An enlarged heart is not called an enlarged heart, but is clinically called an enlarged heart. Patients with enlarged hearts are often caused by diseases that increase the load on the heart, so patients should actively treat the underlying disease. Patients with hypertension should actively control their blood pressure, patients with coronary artery disease should actively improve the insufficient blood supply to the heart muscle, and patients with organic heart valve disease should be actively treated with valve replacement if surgery is indicated. Patients with enlarged hearts should also be given long-term drugs that inhibit myocardial remodeling, such as angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists. In case of heart failure, diuretics and other drugs should be given to reduce the symptoms of heart failure. Beta-blockers, such as betalactam, should also be given for a long time to improve the long-term prognosis of the patient.
