Left ventricular diastolic dysfunction, first clarify the cause and then use drugs, such as the presence of left ventricular hypertrophy, hypertensive heart disease, etc., you can choose calcium channel blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, β-blockers and so on. 1. Calcium channel blockers: Calcium channel blockers are mainly used to reduce the concentration of calcium in cardiomyocytes and lower blood pressure, thus reducing the occurrence of myocardial hypertrophy, and can effectively improve the problem of left ventricular diastolic dysfunction, and can be used as drugs such as verapamil in clinical practice. 2. Angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists: can reduce blood pressure, improve myocardial remodeling to improve diastolic function, can be used for hypertensive heart disease and coronary heart disease caused by cardiac left ventricular diastolic hypoplasia, the bed can choose enalapril maleate, valsartan, chlorentin and so on. 3. β-blockers: oral administration of such drugs can slow down the heart rate to improve diastolic function, improve myocardial compliance, thus reducing the left ventricular diastolic hypoplasia caused by myocardial hypertrophy, the clinic can choose metoprolol tartrate, bisoprolol and so on. If left ventricular diastolic dysfunction is found, it is recommended to consult the cardiovascular medicine department of regular hospitals for diagnosis and treatment.
