Enlarged left ventricle generally refers to left ventricular hypertrophy. Left ventricular hypertrophy may be caused by exercise load, high blood pressure, long-term late night and other factors, you can pay attention to avoid strenuous exercise, control blood pressure, maintain sufficient sleep time. 1. Exercise load: left ventricular hypertrophy may be caused by coronary heart disease, myocarditis and other diseases, easy to affect the diastolic function of the heart, may lead to a decline in the patient’s cardiac function, and strenuous exercise will aggravate the myocardial oxygen consumption caused by cardiac exhaustion, resulting in patients with respiratory distress, cyanosis, chest pain, palpitations and other symptoms, so left ventricular hypertrophy of the patient should pay attention to avoid strenuous exercise. 2. High blood pressure: left ventricular hypertrophy may also be due to hypertension resulting in increased arterial pressure, the left ventricle needs to contract to produce greater pressure to shoot blood into the arteries, so that cardiomyocytes appear to cardiac hypertrophy caused by the left ventricular hypertrophy patients should pay attention to low-salt, low-fat, and weight control will be the blood pressure control at the normal level to avoid aggravating the left ventricular hypertrophy. 3. Long-term late night: may lead to increased cardiac load caused by left ventricular hypertrophy, so patients with left ventricular hypertrophy should maintain a good work and rest routine, to maintain adequate sleep, conducive to the stabilization of the patient’s heart rate and blood pressure, to avoid excessive late night, exacerbate myocardial injury caused by left ventricular hypertrophy. Patients with left ventricular hypertrophy should go to a professional hospital, carry out relevant examinations to clarify the cause of the disease, and then follow the doctor’s instructions for systematic treatment.
