Left ventricular fullness, also known as left ventricular hypertrophy, is an abnormal state of the heart. If left unchecked, it can eventually lead to heart failure. The most common causes of left ventricular hypertrophy are high blood pressure, coronary artery disease, aortic stenosis and cardiomyopathy. These diseases put a heavy burden on the patient’s heart and overwork the heart muscle, which can lead to hypertrophy and dilatation of the left ventricle. The original function of the hypertrophied cardiomyocytes will be affected, thus reducing the blood flow reserve of the heart and coronary arteries. During strenuous exercise, the body’s oxygen consumption increases, the heart’s contractile capacity decreases, the ejection volume decreases and cannot meet the body’s needs, and eventually develops into heart failure. Targeted treatment should be actively pursued to prevent the development of heart failure. Patients diagnosed with left ventricular hypertrophy, it is recommended to maintain a calm state of mind, do not be too nervous, quit smoking and limit alcohol, appropriate activities, enhance physical resistance, avoid colds and other diseases, induced viral infections.
