Cardiac hypertrophy is an organic pathological change of the heart caused by various heart diseases, and some of them can be normalized with effective treatment. Cardiac hypertrophy is a thickening of the heart wall and enlargement of the heart’s shape caused by overloading of the heart. Common diseases that cause cardiac hypertrophy include dilated cardiomyopathy, hypertension, valvular disease, coronary artery disease and so on. If the cardiac hypertrophy is caused by short-term overloading of the heart, it can be recovered by correcting the cause of the disease in time, while the chance of recovering from long-term causes or those difficult to correct the cause of the disease is small. If cardiac hypertrophy is detected after examination, it is necessary to treat the cause of cardiac hypertrophy. For example, cardiomegaly requires anti-heart failure treatment; hypertension requires regular use of antihypertensive drugs to control blood pressure; valvular disease requires valvuloplasty or valve replacement surgery; coronary artery disease requires lipid-lowering, antiplatelet, and vasodilator treatment. The discovery of cardiac hypertrophy, need to clarify the cause of the disease, under the guidance of the doctor for standardized treatment.
