Reliable endothelial function testing: at our fingertips?
Noninvasive testing for the purpose of cardiovascular risk stratification has been a “holy grail” of Cardiology for some time. As the endothelium plays such a key role in normal vascular health and endothelial dysfunction is such an early event in atherogenesis, the appeal of endothelial function testing for risk stratification is easy to understand. Nevertheless, the goal of developing a nonin...
متن کاملEndothelial Function Peripheral Vascular Endothelial Function Testing as a Noninvasive Indicator of Coronary Artery Disease
OBJECTIVES We studied whether assessment of endothelium-dependent vasomotion (EDV) with brachial artery ultrasound (BAUS) imaging predicts the presence or absence of coronary artery disease (CAD) as defined by exercise myocardial perfusion imaging (ExMPI). BACKGROUND Abnormalities in EDV can be detected in arteries before the development of overt atherosclerosis, and its presence may predict po...
متن کاملPancreatic function testing: serum PABA measurement is a reliable and accurate measurement of exocrine function.
A comparison between the NBT-PABA/14C-PABA test (NBT-PABA, n-benzoyl-tyrosyl para-aminobenzoic acid) using the PABA excretion index (PEI) and serum PABA estimation at 90 minutes has been made in 42 consecutive subjects attending for investigation of possible pancreatic disease to a District General Hospital (DGH). The PEI was unobtainable or incorrect on 38% of occasions compared with 9% for th...

متن کاملTesting endothelial vasomotor function: nitric oxide, a multipotent molecule.
The initial description in 1980 by Furchgott and Zawadzki1 of endothelium-derived vasodilator factor has stimulated more than 2 decades of intense research to delineate the basic biology of the endothelium and its importance in the clinical setting.2 Endotheliumderived vasodilator factor has been identified as nitric oxide (NO).2 It is formed in endothelial cells from the amino acid L-arginine ...
