Data describing the flow-mediated vasodilation responses and blood pressure in young adult humans after a single dose of oral edible emu oil.

ABSTRACT: The data provided herein include flow-mediated vasodilation responses, represented by changes in arterial diameter, and blood pressure in young adults after a single oral dose of edible emu oil or placebo (cross-over design). Ten healthy men and 10 healthy women participated. Increased blood flow in the antebrachial region was induced by inflating a pressure cuff and subsequently releasing the pressure by deflating the cuff. After the release, the arterial diameter was continuously monitored for 110 sec using ultrasonic diagnostic equipment. The changes in the arterial diameter from 20 to 110 sec post-cuff deflation are described in line graphs and tables. In addition, systolic and diastolic blood pressure data are provided in a table.

Project description:BackgroundGlomerular hyperfiltration resulting from an elevated intraglomerular pressure (Pglom) is an important cause of CKD, but there is no feasible method to directly assess Pglom in humans. We developed a model to estimate Pglom in patients from combined renal arterial pressure and flow measurements.MethodsWe performed hemodynamic measurements in 34 patients undergoing renal or cardiac angiography under baseline conditions and during hyperemia induced by intrarenal dopamine infusion (30 μg/kg). For each participant during baseline and hyperemia, we fitted an adapted three-element Windkessel model that consisted of characteristic impedance, compliance, afferent resistance, and Pglom.ResultsWe successfully analyzed data from 28 (82%) patients. Median age was 58 years (IQR, 52-65), median eGFR was 95 ml/min per 1.73 m2 (IQR, 74-100) using the CKD-EPI formula, 30% had microalbuminuria, and 32% had diabetes. The model showed a mean Pglom of 48.0 mm Hg (SD=10.1) at baseline. Under hyperemia, flow increased by 88% (95% CI, 68% to 111%). This resulted in a 165% (95% CI, 79% to 294%) increase in afferent compliance and a 13.1-mm Hg (95% CI, 10.0 to 16.3) decrease in Pglom. In multiple linear regression analysis, diabetes (coefficient, 10.1; 95% CI, 5.1 to 15.1), BMI (0.99 per kg/m2; 95% CI, 0.38 to 1.59), and renal perfusion pressure (0.42 per mm Hg; 95% CI, 0.25 to 0.59) were significantly positively associated with baseline Pglom.ConclusionsWe constructed a model on the basis of proximal renal arterial pressure and flow velocity measurements that provides an overall estimate of glomerular pressure and afferent and efferent resistance in humans. The model provides a novel research technique to evaluate the hemodynamics of CKD on the basis of direct pressure and flow measurements.Clinical trial registry name and registration numberFunctional HEmodynamics in patients with and without Renal Artery stenosis (HERA), NL40795.018.12 at the Dutch national trial registry (toetsingonline.nl).
