Update Date: 2024-06-04 Source: Network

Cardiac function includes systolic function and diastolic function. Left ventricular diastolic dysfunction is commonly seen in left ventricular hypertrophy caused by various reasons and restrictive cardiomyopathy. Left ventricular systolic dysfunction is seen in a series of organic heart diseases, including myocarditis, coronary heart disease, dilated cardiomyopathy, alcoholic cardiomyopathy, ischemic cardiomyopathy, and patients in the late stage of diastolic dysfunction.

For patients with diastolic dysfunction, there are usually no obvious symptoms in the early stage, and they may experience symptoms such as shortness of breath and fatigue after exertion or activity. Once left ventricular diastolic dysfunction is found, it is recommended to seek medical attention as soon as possible and receive standardized diagnosis and treatment under the guidance of a professional doctor. Beta blockers such as metoprolol and calcium channel blockers such as diltiazem can be used as appropriate to improve diastolic function and symptoms.

Left ventricular systolic dysfunction manifests as pulmonary congestion, dyspnea, as well as signs of systemic congestion and water-sodium retention, including carotid dilation, pleural effusion, abdominal effusion, edema of both lower extremities, etc. Cardiac stimulants such as digoxin, diuretics such as furosemide, angiotensin-converting enzyme inhibitors such as enalapril, beta blockers such as metoprolol, and aldosterone receptor antagonists such as spironolactone can be used to inhibit myocardial remodeling, improve systolic function, and patient prognosis.
