40-year-old left ventricular hypodiastolic function need to clarify the cause, such as hypertension, coronary heart disease, hypertrophic cardiomyopathy, etc., to be antihypertensive, reduce obstruction and other treatments, most of them can be restored, do not have to panic. 1. Hypertension: due to prolonged elevation of blood pressure but ventricular compensatory hypertrophy, need to strictly monitor blood pressure, in daily life, light diet, appropriate exercise, to be antihypertensive drugs, such as oral hydrochlorothiazide, nifedipine and other drugs treatment. 2. Coronary heart disease: if diagnosed with coronary heart disease, resulting in left ventricular hypodiastolic function, need to eat a reasonable diet, such as eating less high cholesterol, high sugar and other foods, increase exercise, to regulate lipid stabilization, anti-platelet, anticoagulant therapy, such as atorvastatin, aspirin, warfarin and so on. 3. Hypertrophic cardiomyopathy: due to myocardial hypertrophy, heart expansion is limited, resulting in ventricular diastolic dysfunction, the need to reduce the left ventricular outflow tract obstruction, anti-heart failure, anti-atrial fibrillation and other symptomatic treatment, such as taking metoprolol, hydrochlorothiazide, amiodarone and other drugs. Left ventricular hypodiastolic function at the age of 40 years should be timely medical treatment, under the guidance of professional doctors to develop a treatment plan.
