title: Red cell deformability and other haemorheological variables in stable coronary artery disease.
abstract: In this study, red cell deformability and other haemorheological variables were measured in 40 patients who underwent cardiac catheterization for the investigation of chest pain. The patients were divided into two groups - those with extensive disease and those with less extensive or no disease. Deformability was assessed by a filtration method. There were no significant differences in filterability, haematocrit, plasma viscosity or plasma fibrinogen between the two groups of patients. However, those with extensive disease had significantly higher blood viscosity than those with less extensive disease. Thus the study was able to demonstrate an association between blood viscosity and extent of coronary artery disease but not between the individual determinants of blood viscosity (red cell deformability, plasma fibrinogen and haematocrit) and extent of disease.
