Coronary artery disease (CAD) is the leading cause of cardiovascular mortality worldwide. Even more, it is projected that CAD mortality rates will double from 1990 to 2020, with approximately 82% of the increase attributable to the developing world [5]. Prevention and targeted control of risk factors for CAD could potentially reduce the impact of CAD in the developing world.

Many scientists indicate the significance of the monitoring of hemorheological patterns during various forms of the ischemic heart disease [2,6]. The increased RBC aggregation was observed in the patients in the following order: unstable angina, acute myocardial inf- arct. The best correlation was observed by integration of large aggregate fraction as a function of shear stress [1].[/su_animate]

Abstract

[su_animate type=”bounceInDown”]

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]

Nervous system is concerned to be a structure consisted of dynamic glio-neuro-synaptic networks that are able to morphological and functional modulation under external stimuli. Hemorheological shock is a external stimuli and stressor for brain.

A particular link, which is involved in various stages of hemorheological shock, is blood rheology.biz. The aim of our work was a comprehensive rheological properties of blood: red blood cell aggregation, deformation of erythrocytes, plasma viscosity, hematocrit at different degrees of severity of experimental hemorrhagic shock.
