Abstract
Tissue blood flow is determined by rheological properties of blood as well as by vascular resistance. In acute myocardial infarction patients who participated in the TIMI I trial, we compared the effects of recombinant tissue plasminogen activator (rt-PA) and streptokinase (SK) on blood rheological properties and plasma fibrinogen concentration. Blood viscosity was determined by using a coaxial cylinder viscometer at shear rates, γ, of 0.01-200 sec-1. Red blood cell (RBC) deformability was studied by filtration through poly-carbonate microsieves with pore size of 3 and 5 μm. Therapy with rt-PA resulted in slight decreases but statistically significant in blood viscosity from 5.2±0.5 to 4.9±0.4 cP (γ = 52 sec-1), plasma viscosity from 1.36±0.09 to 1.32±0.06 cP, and plasma fibrinogen from 0.26 ± 0.04 to 0.21 ±0.03 g/dl. SK therapy resulted in reductions in blood viscosity from 5.1 ± 0.5 to 4.6 ± 0.3 cP, plasma viscosity from 1.26 ± 0.10 to 1.16 ± 0.03 cP, and fibrinogen from 0.26 ± 0.06 to 0.10 ± 0.05 g/dl. Changes observed with SK were significantly greater than those observed with rt-PA (all p <0.05), and the differences persisted at 10 days after thrombolytic therapy. RBC deformability was similar in the two groups. The greater reduction of blood viscosity after SK than rt-PA suggests that, for a given degree of arterial patency, myocardial blood flow may be better maintained with SK than rt-PA in patients with acute myocardial infarction.
