Flow-Mediated Vasodilation Is Not Attenuated in Hypertensive Pregnancies Despite Biochemical Signs of Inflammation
Background. Our objective was to evaluate endothelial function and markers of inflammation during and after pregnancy in normal pregnancies compared to pregnancies complicated with hypertension or preeclampsia (PE). Methods and Results. We measured endothelium-dependent brachial artery flow-mediated vasodilation (FMD) and high sensitive C-reactive protein (hsCRP), interleukin-6 (IL-6), and tumo...
متن کاملFlow - Mediated Vasodilation *
Brachial arterial flow-mediated dilation (FMD), assessed by high-resolution ultrasonography, reflects endothelium-dependent vasodilator function. FMD is diminished in patients with atherosclerosis and with coronary risk factors, and improves with risk-reduction therapy. Therefore, the measurement of FMD can be a good prognostic instrument in preventive cardiology, is useful to predict short-ter...
متن کاملHaemoglobin and flow-mediated vasodilation.
A low [Hb] (Hb concentration) is out-balanced by peripheral vasodilation via mechanisms that are incompletely understood. Peripheral vasodilation is influenced by NO (nitric oxide) released from vascular endothelium in response to increased vessel wall shear stress, and absorption by Hb is the main mechanism by which the bioactivity of NO is disarmed. Thus we propose that graded NO absorption i...
متن کاملImpaired endothelium-dependent flow-mediated vasodilation in hypertensive subjects with hyperaldosteronism.
BACKGROUND Recent studies suggest that aldosterone may impair endothelium-dependent vascular function through suppression of nitric oxide formation. Assessments of forearm blood flow or arterial compliance suggest a similar effect in humans. The present study was designed to determine whether chronic aldosterone excess in subjects with resistant hypertension impairs endothelium-dependent vascul...
متن کاملPrognostic significance of brachial flow-mediated vasodilation.
There is currently much research devoted to the study of vascular biology in intact humans. These efforts aim to translate findings from the basic science arena to a better understanding of the pathophysiology of atherosclerosis and its complications. Markers of vascular risk have been used as surrogate end points in treatment studies. More recently, long-term studies have emerged that speak to...
