Many studies in hypertensive humans and animals have shown that increased blood viscosity is in direct relation with essential hypertension. The aim of our studies was to investigate the effects of chronic hematocrit value changes on arterial blood pressure and kidney function in genetically induced hypertension. To this end, we studied the effects of several interventions, designed to increase...

The effect of isovolemic hemodilution on red blood cell flow distribution was studied in complete self-contained microvessel networks of the rat mesentery. Hematocrit, diameter, and length of all vessel segments as well as the topological structure were determined in control networks (systemic hematocrit, 0.54) and after hemodilution (systemic hematocrit, 0.30). Hemodilution was performed by ex...

The article entitled "Hematocrit Compensation in Electrochemical Blood Glucose Monitoring Systems" by Teodorczyk and colleagues in this issue of Journal of Diabetes Science and Technology demonstrates that the OneTouch(®) Verio™ glucose meter meets current regulatory expectations for glucose meter performance and is relatively free from interference by hematocrit. The lack of influence of hemat...

CROWELL, JACK W., ROBERT G. FORD AND VIRGINIA M. LEWIS. Oxygen transport in hemorrhagic shock as a function of the hematocrit ratio. Am. J. Physiol. I g6(5) : I 033-1038. I g5g.-The oxygen consumption, arterial and venous oxygen concentration, and the arterial blood pH were measured, and the cardiac output, peripheral resistance and maximum oxygen transport capacity determined in 75 dogs with d...

Anemia treatment with epoetin has led to dramatic increases in hematocrit levels since 1989. Studies have demonstrated that morbidity and mortality rates are lower when hematocrit values are within the Disease Outcomes Quality Initiative (DOQI) target range (33 to 36%). Recently, clinical studies demonstrated that patients without cardiovascular disease exhibited lower morbidity rates and impro...

Baseline data from the Gubbio Population Study in north central Italy were used to investigate the relation of hematocrit to blood pressure and hypertension among 2,809 men and women aged 25-74 years. Independent of gender, age, and other confounders, the hypertensive group had a higher hematocrit than the nonhypertensive group (p<0.001). In comparison with the untreated hypertensive group, the...

Hematocrits of 131 cerebral infarction cases were correlated with the outcome at 2 weeks. Bivariate analysis showed that cases with more intense admission deficit had lower admission hematocrit and that cases with poorer outcome had lower Day 2 and 4 hematocrits. However, multivariate analysis of several prognostic factors (including hematocrit, glycemia, blood pressure, age, and sex) showed th...

This retrospective study investigated the correlations between red blood cell (RBC) count, hemoglobin, and hematocrit on admission, and mortality in 140 patients with subarachnoid hemorrhage (SAH). Correlations between the hematological parameters RBC count, hematocrit, hemoglobin, white blood cell (WBC) count, and platelet count on admission and mortality were investigated. Association of each...
