Objective: Radial endothelial dysfunction may occur after transradial coronary angiography (CAG). This study aimed to make a comparative evaluation of the radial endothelial functions before and after catheterization between three different radial access sites: left radial (LR) artery, left distal radial (LDR) artery, and right radial (RR) artery. Methods: Seventy patients scheduled for elective transradial CAG and intervention from September 6, 2017 to March 6, 2018 were consecutively enrolled. Radial artery endothelial functions of the catheterization arm were measured by flow-mediated vasodilation (FMD) upon admission, at 24 hours, and 2 months following the procedure. Results: LR access was used in 17 patients, whereas the LDR and the RR access were used in 27 and 26 patients, respectively. Basal radial diameters and FMD median values measured on the intervention arm were found to be similar between groups (LR 3.04±0.29 mm, 13.33%; LDR 2.79±0.31 mm; 13.64%; RR 2.74±0.29 mm; 12.52%, p=0.952). The radial vasodilation percentage change expressed as median decreased in all groups 24 hours after the procedure; however, the one with the LDR access was found to be significantly higher than with the LR (9.7% vs. 6.25% p=0.013) and the RR access (9.7% vs. 3.39 p<0.001). A partial recovery of endothelial functions was seen at 2 months after the procedure, approximating to basal values (11.11%; 12%; 10.62%, p=0.079, respectively). Conclusion: Radial artery functions deteriorate early after transradial catheterization. The LDR access seems safer than the other conventional radial access sites in terms of preservation of radial endothelial functions.
