Abstract

Previous studies have explored the association between hemorheologic alterations and aspirin resistance, pointing out the possible interaction between hematologic components and platelet responsiveness to antiplatelet drugs. The aim of this study was to evaluate the association between hemorheologic variables and residual platelet reactivity in patients with acute coronary syndromes (ACSs) who underwent percutaneous coronary intervention on dual antiplatelet therapy. The study population included 528 patients with ACSs. Hemorheologic studies were performed by assessing whole blood viscosity at 0.512 and 94.5/second, plasma viscosity, and erythrocyte deformability index. Post-treatment platelet reactivity was investigated by measuring platelet aggregation by adenosine 5′-diphosphate (ADP) 10 μmol and a value >70% was defined as high ADP platelet reactivity.
