[State of hemostasis and blood rheology in congestive circulatory insufficiency].

One hundred and ninety-eight patients with congestive circulatory insufficiency were examined; 54 had stage IIA, 88 stage IIB, and 56 stage III of the disease. Blood viscosity, blood platelet and erythrocyte aggregation, fibrinogen disintegration products, and soluble fibrin were determined and the protamine sulfate test was performed. Statistically significant reduction of hematocrit, increase of erythrocyte aggregation, dysfunction of blood platelets, and increase in the content of products of fibrinogen and fibrin disintegration were revealed with progression of congestive circulatory insufficiency. These changes are evidence of disseminated intravascular coagulation in such patients and are important in prognostication.
