Systemic endothelial dysfunction as an early predictor of adverse outcome in heart failure.
OBJECTIVE Endothelial dysfunction is an early event in the natural progression of heart failure. Increased oxidative stress has been linked to impaired endothelial function and both may play a prognostic role. METHODS AND RESULTS Endothelium-dependent and endothelium-independent vasodilatation were determined in 289 patients with mild left ventricular dysfunction by measuring forearm blood fl...
متن کاملReproducibility of blood flow and post-occlusive reactive hyperaemia as measured by venous occlusion plethysmography.
Venous occlusion plethysmography is commonly used as a tool to assess BF (blood flow) and VR (vascular resistance) at baseline and during PORH (post-occlusive reactive hyperaemia). However, little is known about the reproducibility of this method. The purpose of the present study was to investigate short- (hours) and medium (week)-term reproducibility of forearm, calf and thigh BF and VR at bas...
متن کاملCold pressor test using strain-gauge plethysmography.
This laboratory activity is designed to teach students how to measure forearm muscle blood flow (FBF) to describe the mechanisms of peripheral blood flow thermal regulation in healthy subjects. The cold pressor test (CPT) is the clinical procedure used in the experiment to induce arterial vasoconstriction. Strain-gauge plethysmography is applied on the patient's forearm to noninvasive monitor v...
متن کاملPeak cardiac power output, measured noninvasively, is a powerful predictor of outcome in chronic heart failure.
BACKGROUND The cardiac output (CO) response to exercise and other invasively derived hemodynamic variables has been variably described to provide better prognostication than peak V(O(2)) in patients with chronic heart failure. Using noninvasive measurements of CO during exercise, we compared the prognostic value of peak CO and cardiac power to peak V(O(2)) in chronic heart failure patients. M...
متن کاملInflammation, as measured by the erythrocyte sedimentation rate, is an independent predictor for the development of heart failure.
OBJECTIVES Our objective was to explore inflammation, measured as erythrocyte sedimentation rate (ESR), as a predictor for the development of heart failure (HF). BACKGROUND In recent years, evidence of the importance of inflammation in the pathophysiology of HF has emerged, and various inflammatory markers have been found to predict future HF. Erythrocyte sedimentation rate is an inexpensive ...
