Left ventricular hypertrophy is the thickening of the ventricular wall and enlargement of the chambers of the left ventricle. This condition can be a physiological manifestation, such as the natural response of the heart muscle to aerobic exercise or training, so some athletes can exhibit hypertrophy of the left ventricle. It can also be a pathological change due to cardiovascular disease, commonly caused by hypertension, coronary artery disease, mitral stenosis or regurgitation, proliferative obstructive cardiomyopathy, dilated cardiomyopathy, etc. For physiological changes, treatment is generally not required, but if the symptoms are caused by pathological factors, serious ones may lead to the manifestation of heart failure, which requires active treatment of the primary disease, while symptomatic treatment with drugs can be chosen to control the progress of the disease.
