Abstract: Changes in hemorheological parameters were studied in patients with ischemic cerebrovascular disease and elderly healthy men who ingested ethanol at 0.5 and 1 g/kg body weight. Following ingestion of 1 g/kg, but not 0.5 g/kg of ethanol, there were significant changes in hemorheologic factors. Whole blood viscosity (WBV, shear rate: 18.8, 37.5, 75, 150, 350 sec−1) and blood viscosity corrected for hematocrit (BVC) were increased. WBV and BVC at high shear rate were increased and red blood cell deformability impaired in patients with ischemic cerebrovascular disease, while those factors were not significantly changed in healthy men. It is considered that ethanol ingestion could has bad influences for the microcirculation in patients with ischemic cerebrovascular disease.
