[Regulation of arterial pressure in healthy subjects and hypertensive patients of old age].
Central hemodynamics, microcirculation and vascular reactivity were studied in 61 patients with essential hypertension stage II and 64 healthy subjects at the age of 40 to 74 years. The process of aging is accompanied with elevation of arterial pressure and peripheral vascular resistance, left ventricular diastolic dysfunction, reduction of vascular sensitivity to noradrenaline and cold stimulation, deterioration of microcirculation and augmentation of oxygen consumption of the myocardium.
