The functional condition of resistance arteries in human hands was monitored with a noninvasive test. Blood flow velocity changes (Doppler flow meter) were monitored in the radial artery before and after a 1-min stop flow in the hand under conditions of stable systemic arterial pressure. In addition, the most significant parameter of hemorheological disorders in microcirculation, RBC aggregability, was investigated in the same patients' blood samples.[/su_animate]

Abstract
[su_animate type=”bounceInUp”]
It could be conjectured that the hemorheological disorders are involved in development of the ischemic heart disease. But this fact was so far insufficiently cleared up. The present studies were carried out in patients with various forms of chronic ischemic heart disease. We investigated the most significant factor of rheological disorders in the microcirculation, the erythrocyte aggregability, with a technique that provided us with the direct and quantitative data.[/su_animate]
Assessment of a functional condition of resistive arteries at the person

It is notable that the resistance arteries play the leading part in regulation of physiological parameters of the circulation system. It is proposed a new noninvasive method of appraisal of functional state of the human arm resistance arteries. The method is based on research of postischematic hyperemia arising as a result of standard stopping of local blood flow for one minute. The measurement of blood flow velocity in the radial artery of patients is performed by means of ultrasonic device which work is based on Doppler’s effect. For determination of functional state of the resistance arteries a new notion of resistance index is introduced. By this parameter the state of resistance arteries of human arm is investigated at different diseases (Raynaud’s phenomenon, arterial hypertension, diabetes mellitus, etc.).
