[Changes in hemorheological parameters during physical exertion in coronary disease patients].
Blood viscosity and filtrability have been studied in 7 patients with ischemic heart disease and in 9 control subjects before and after maximal stress test on cycloergometer. The diagnosis of ischemic heart disease has been previously established on the basis of the clinical history, abnormal stress test or coronary arteriography. No significant differences were observed, at rest, in the two groups. On the contrary, after stress test blood filtrability resulted significantly reduced in ischemic patients when compared to controls. Blood viscosity resulted substantially unchanged in both groups. Our data may suggest the existence of an alteration in blood filtrability during stress test with a possible pathogenetic role.
