The relationship between blood viscosity, hematocrit (Hct), and mean arterial blood pressure (MAP) was studied in a healthy population of 91 men and 66 women with an average age of 30.6 ± 8.0 years, from the city of Victoria de Durango (1800 m elevation). In women and men, Hct values were 42.4% ± 2.9% and 47.2% ± 2.3%, blood viscosities were 4.5 ± 0.7 and 6.1 ± 1.0 cP, and MAP was 83.0 ± 6.8 an...

Background The extracellular volume fraction (ECV) is a surrogate marker for diffuse myocardial fibrosis. ECV is calculated from preand post-contrast T1 maps and corrected for hematocrit (Hct). Current workflows are cumbersome, but an automated ECV map tool simplifies this and could promote adoption into routine clinical practice. We assessed the performance of automated ECV maps versus convent...

Urban stormwater is responsible for recurrent mortality events of coho salmon (Oncorhynchus kisutch) documented in the US Pacific Northwest. Currently, toxic mode action unknown; however, often associated with large increases hematocrit (Hct). We found that hemoconcentration and red cell swelling may offer a partial explanation increased Hct, based on total hemoglobin reduced mean concentration...

OBJECTIVES The goal of this study was to investigate the relationship between hematocrit (Hct) and left ventricular mass index (LVMI) and LV hypertrophy (LVH) in subjects without known hypertension or cardiovascular disease in the Framingham Heart study. BACKGROUND Anemia may be an independent risk factor for cardiovascular disease in the general population. One potential explanation for this...

PURPOSE This investigation quantified the effect of changes in plasma osmolality on the measurement of hematocrit (Hct) and the implications for the subsequent use of these data to calculate changes in plasma volume and application to the World Anti-Doping Agency Athlete Biological Passport. METHODS Two groups of eight male volunteers visited the laboratory after an overnight fast. In study 1...

conclusions although some studies showed association between anemia and extubation failure, the current study could not confirm it. the study showed that males, regardless of the hct level, had a better extubation success rate than those of females. results there was no significant association between the level of hct concentration and extubation failure (8.9% vs. 9.2%, p = 0.507). gender and a...

background: it is intriguing and imperative that the comparison of the iron preparations in hemodialysis (hd) patients. th is study aimed to observe the short-term effi cacy of parenteral iron sucrose and ferric chloride in hd patients. materials and methods: this was a consecutive 10-week single-blind study in taiwan. an intravenous iron supplement of 100 mg/week was administered as an infusio...

OBJECTIVES This study sought to determine the relationship between blood viscosity and iron deficiency and their impact on symptoms and exercise function in adults with cyanotic congenital heart disease. BACKGROUND Iron deficiency is believed to raise whole blood viscosity in cyanotic congenital heart disease, although available data are inconsistent. METHODS Thirty-nine cyanotic adults wer...

lymphocyte cd4 + count, a standard laboratory test for staging of hiv infection, is expensive and unavailable in resource-restricted countries. total lymphocyte count (tlc) and hemoglobin (hb) are recommended as simple & inexpensive surrogates. the aim of this study was to assess the correlation, sensitivity and predictive power of these parameters as substitutes for cd 4 count. one hundred hiv...

ABSTRACT. Anemia has long been known to be a complication of end-stage renal disease (ESRD), and it has been linked to cardiovascular morbidity and mortality. Although kidney transplant recipients (KTR) are prone to experiencing cardiovascular outcomes, little is known about the epidemiology of anemia in this population. With few exceptions, studies to date have not fully evaluated the associat...
