The influence of acute variations in hematocrit on the QRS complex of the Frank scalar electrocardiogram was studied in 31 patients with severe polycythemia secondary to cyanotic congenital heart disease and in eight patients with anemia due to thalassemia. Moderate reduction of the hematocrit in the polycythemic group resulted in a significant increase in the magnitude and a delay in both left...

Hemodynamic stresses are involved in the development and progression of vascular diseases. This study investigates the influence of mechanical factors on the hemodynamics of the curved coronary artery in an attempt to identify critical factors of non-Newtonian models. Multiphase non-Newtonian fluid simulations of pulsatile flow were performed and compared with the standard Newtonian fluid model...

Severe anemia in mothers is associated with low birth weight, premature delivery, and fetal death. This cross-sectional study aimed to determine the relationship between the hemoglobin level and hematocrit of mothers and prenatal complications. Subjects consisted of 1100 pregnant that had referred to Bandar Abbas’ Shariati hospital in 2007 that had a single, viable fetus with cephalic presentat...

BACKGROUND Patients and physicians expect accurate whole blood glucose monitoring even when patients are anemic, are undergoing peritoneal dialysis, or have slightly elevated ascorbate levels. The objective of this study was to estimate analytical error in two consumer and two hospital glucose meters contributed by variations in hematocrit, maltose, ascorbate, and imprecision. METHODS The inf...
