What is Vascular Dysfunction of Brachial Artery After Transradial Access for Coronary Catheterization about?

## Objectives: The aim of this study was to investigate the effect of diagnostic transradial catheterization on vascular function of upstream brachial artery (ba). ## Background: The transradial access has recently become an alternative to transfemoral cardiac catheterization. a potential caveat of this approach lies in possible sustained physical radial artery (ra) damage. ## Methods: We studied 30 patients (age 61 +/- 11 years) undergoing diagnostic coronary angiography with the transradial access (5-f). endothelium-dependent, flow-mediated vasodilation (fmd) was measured before and at 6 and 24 h after catheterization of the right-sided ra and ba with high-resolution ultrasound. the left-sided ra served as a control. ## Results: Transradial catheterization significantly decreased fmd in the ra (overall mean 8.5 +/- 1.7% to 4.3 +/- 1.6%) and the upstream ba (overall mean 4.4 +/- 1.6% to 2.9 +/- 1.6%) at 6 h. subgroup analysis showed that fmd of both arteries at 6 h was significantly lower in active smokers and that it only remained impaired at 24 h in this group, whereas nonsmoker fmd fully recovered. the degree of ba but not ra fmd dysfunction was related to the number of cathete
