Previous studies have demonstrated that Separan AP-30, a drag-reducing polymer, significantly decreased the formation of atherosclerotic plaques in rabbits fed a high-cholesterol diet. Furthermore, Separan AP-273, a polymer similar to but longer than Separan AP-30, markedly increased cardiac output in
