[Complex study of the state of the microcirculatory bed at different stages of circulatory failure].
The state of microcirculation was studied on 103 patients with the 1st-3rd degree of circulatory failure due to post-myocardial infarction cardiosclerosis and rheumatic valvular heart disease. The dynamics of the local blood flow in the skin of the left forearm (by the H-clearance method) as well as platelet aggregation ability were studied, conjunctival biomicroscopy and T-V capillaroscopy were performed. Already at early stages, patients with circulatory failure were observed to have changes in the microcirculation accompanied by a decrease in the volume velocity of the tissue (capillary) blood flow. As the circulatory failure developed, the aggravation of morphofunctional disturbances was accompanied by a significant retardation both of linear and volume velocity of the capillary blood flow as well as by an increase in aggregation properties of platelets.
