This study presents characteristics of hemorheology for six patients during long-term support (85-144 days) on a Novacor left ventricular assist device (LVAD) as a bridge-to-cardiac transplantation. Results indicate that a certain "baseline" rheology can be identified in patients whose support was uneventful. However, in the patients who had one or more(More)
Hemorrheology was studied in patients undergoing artificial heart support as a bridge-to-cardiac transplantation. Abnormal hemorrheology was seen in two patients, one on a Jarvik-7 total artificial heart, and the other on a Novacor left ventricular assist device. Both of these patients suffered neurologic episodes. The rheology of these two patients(More)
The erythrocyte rigidity of patients suffering from severe peripheral vascular disease (PVD) was measured by a filtration method using 3 microns pore size filters. Filtration pressures for both PVD patients and normal subjects showed a cell volume dependency, and patient filtration pressures were normalized to cell volume to evaluate intrinsic, ie,(More)
Blood rheologic properties were studied in 11 patients on Novacor LVAS support (1-126 days) as a bridge to transplantation. Overall, these patients showed slight increases in mean blood viscosity and red cell rigidity. Their mean plasma fibrinogen was in the upper normal range. However, the degree of rheologic change observed, and the individual factors(More)
Autoradiographic studies following a single i.p. injection of3H-thymidine were performed in liver and kidney parenchyma of new-born and young adult rats at different ages (1, 2, 4, 7, 12, 18, 24, 30, 60 and 120 days). In 1-day-old animals the tritium index (i.e. percentage of DNA synthesizing nuclei) of both organs is lower than in the rat embryo. From 1–4(More)
The rheological properties of blood were studied in patients supported by both the Jarvik-7 total artificial heart (TAH) and Novacor left ventricular assist device (LVAD) as a bridge to cardiac transplantation. Both groups of patients had abnormalities in blood rheology which differed according to the type of device implanted as well as on the clinical(More)
