THE STATE OF ENDOTHELIAL REGULATION'S FACTORS OF THE VESSELS TONE IN THE PATIENTS GETTING ON IN YEARS WITH THE STENOSIS OF AORTAL VALVE AND CORONARY HEART DISEASE
The paper discusses changes in endothelial factors regulating vascular tone in the patients getting on in years with stenosis of the aortic valve and coronary heart disease (CHD). The study included 66 patients aged from 60 to 75 years. The results suggest that this groupe of patients with aortic valve stenosis and CHD develop endothelial dysfunction, which manifests varying levels of nitric oxide and endoteleina-1 in the blood. Indicators of endothelial factors regulating vascular tone (NO, ET-1), aortic valve stenosis may be the markers and predictors of severity of acquired defect in the elderly.
