Part of the left ventricular enlargement can be normalized after active treatment, but if organic changes occur, it is difficult to return to normal, to control the progress of the disease. Left ventricular enlargement can be caused by a variety of reasons, and the most common clinical cause is hypertension. In the early stage of left ventricular enlargement, if the blood pressure level can be controlled in time, the enlarged left ventricle may return to normal. In addition to hypertension, severe aortic stenosis, aortic valve insufficiency, ischemic cardiomyopathy, etc., can lead to left ventricular enlargement. If organic changes occur, even if the primary disease is treated in a timely manner, the enlarged left ventricle will not return to normal and the condition will progress gradually, and eventually heart failure may occur. Patients with enlarged left ventricle should control the risk factors, treat the primary disease, go to the hospital in time if the symptoms are obvious, and under the guidance of the physician to slow down the progress of the disease.
