Enlarged left ventricle needs to be treated according to the cause. The main causes of ventricular hypertrophy include high blood pressure, hypertrophic cardiomyopathy and heart valve disease. Conservative or surgical treatment can be chosen to control the progression of the disease. 1. Hypertension: Increased blood pressure and unstable blood pressure, resulting in increased pressure load on the heart, will release excessive catechol and angiotensin ll, resulting in ventricular enlargement. Patients should follow the doctor’s instructions to take oral amlodipine, nifedipine and other drugs, blood pressure level control to the optimal state, can effectively improve the ventricular enlargement. 2.Hypertrophic cardiomyopathy: Ventricular hypertrophy is a serious condition that can lead to an increase in the burden on the heart, and further progression of the condition can lead to ventricular enlargement. Calcium channel blockers, such as felodipine and lacidipine, can effectively reduce LV outflow tract obstruction. If treatment is not effective, percutaneous septal alcohol ablation or surgical septotomy can be performed in a timely manner. 3. Heart valve disease: severe heart valve disease, easy to cause arterial stenosis, further development of the disease will cause left ventricular enlargement. Diuretics such as furosemide should be given as soon as possible. If the stenosis is severe, valve replacement or cardiac bypass surgery is needed. Preliminary diagnosis of left ventricular enlargement, need to further examination, analysis of the cause of the disease and then carry out treatment, the specific use of drugs in strict compliance with the guidance of the doctor.
