[Radioisotopic functional diagnosis in uncomplicated hypertension]

General hemodynamics of 70 patients with hypertonic disease was determined as well as the regional hemodynamics in 22 of them via radio-isotope methods, quantitative radiocardiography (QRCG) and determination of the total coronary output (TCO). Statistically significant decrease of circulating blood volume was radiocardiographically determined as well as increase of stroke volume and ventricular volumes and the indices of post-loading--general peripheral vascular resistance, index of aortic rigidity. The total coronary output is increased in patients with and without manifestations of left ventricular hypertrophy resulting from increased diastolic perfusion pressure.
