Correlation of Hemorheology Parameter Hematocrit with Hemodynamic Factors and Arterial Diseases
The aggregation, dispersion and deformation of cellular components of blood in the vasculature affect blood rheology to a greater extent. At low shear rate erythrocytes tend to aggregate and form rouleaux and at a high shear rate they dis perse and get deformed into ellipsoid with their long axis aligned in the flow direction. While rouleaux formations increase viscosity, dispersion and deforma...
متن کاملThe microcirculation in hypoxia: The center of the battlefield for oxygen.
In the past years the microcirculation has gained increasing attention not only by basic scientists, but also by clinicians and translational researchers. In the clinical scenario, it has been convincingly described that the microcirculation is a key predictor of outcome and of central pathophysiological relevance. A vast body of evidence demonstrates the central role of the smallest vessels in...
متن کاملPeriodontal Disease and Carotid Atherosclerosis: Mechanisms of the Association
Despite advances in its diagnosis and management, cardiovascular disease remains the leading cause of death in western countries. Many risk factors are involved in the development of cardiovascular disease; recently, periodontal disease was recognized as a new risk factor in many epidemiological studies. The association between dental and cardiovascular disease is intriguing for the potential c...
متن کاملGelatine and hydroxyl ethyl starch hypervolemic hemodilution – Effect on hemorheology and retinal circulation in a pig model
The present study was designed to determine the effects of hemodilution with gelatine (GEL) and hydroxyethyl starch (HES) on hematocrit, blood viscosity, systemic hemodynamics, and central retinal arterial blood flow in anaesthetized pigs. 20 pigs were studied. Hypervolemic hemodilution was induced by 30 ml kg-1h-1 GEL (n=10) or HES (n=10) infused over 30 min. The hematocrit decreased comparabl...
متن کاملHemodynamic alteration in diabetic nephropathy measured by renal Doppler ultrasonography: does it predict the outcome of the disease?
We read the article by Dr. Futrakul et al. with interest [1]. They searched for a parameter that was more sensitive than microalbuminuria for early detection of diabetic nephropathy and compared creatinine clearence, fractional excretion of magnesium and intrarenal hemodynamics by renal scintigraphic evaluation. For this purpose, they calculated peritubular capillary flow, efferent arteriolar r...
