Abstract

The transradial approach (TRA) for coronary angiography and percutaneous coronary intervention is associated with lower rates of vascular complications and acute kidney injury when compared to the transfemoral approach (TFA). Urine metabolites and proteins may be useful in identifying the dynamic changes at the vascular endothelial cell level. We attempted to explore the changes in the measurable signals of endothelial and nephron injury within 60 to 90 minutes after catheterization among those with the TRA and TFA approaches. Consecutive patients of a single interventionist who underwent coronary angiography between June 2015 and May 2016 were included. Of the 60 patients included in the analysis, the baseline characteristics were similar between those with a TRA (n = 30) and TFA (n = 30) approach. The values of the biomarkers were natural log transformed for the analysis. We found that the mean values of heat shock protein 27, taurine, and sulfuric acid did not significantly change after the procedure. However, the median value of thioredoxin decreased (P = 0.002) and that of talose increased (P = 0.01) after the procedure. None of the patients in our cohort experienced vascular complications or acute kidney injury. No differences in the values of urinary metabolites (pre, post, and delta) were found between TRA and TFA except for postprocedural thioredoxin. In conclusion, this exploratory study showed no difference in the patterns of acute vascular/renal injury metabolic markers before and after catheterization irrespective of the arterial access site.
