What Are the Causes of Reduced Left Ventricular Relaxation and Contraction Function?
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.
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.
