[Erythrocyte aggregation and fibrinogen derivatives in ischemic heart disease].

Aggregation of erythrocytes was determined in 50 patients with angina pectoris and myocardial infarction and in 20 subjects of the control group by rheoscopy after Schmid-Schoenbein. It is shown that in patients with ischemic heart disease aggregation of erythrocytes is considerably increased and the hydrodynamic strength of the aggregates is greater. The erythrocyte aggregation curve is some patients with ischemic heart disease was of a biexponential character in distinction to that in subjects of the control group, which was of the monoexponential type. It was found that the increase in the strength of the erythrocyte aggregation and in the rate of aggregate formation was due to fibrinogen and its complex compounds with decomposition products.
