Kanic V, et al. - In myocardial infarction (MI) patients undergoing percutaneous coronary intervention (PCI), researchers assessed if radial access (RA) has any impact on acute kidney injury (AKI) incidence. Data were retrospectively analyzed from 3,842 MI patients undergoing PCI in the institution between January 2011 and December 2016, 35.8% of whom had the procedure done radially. In both a non-matched and a propensity-matched cohort, the access site was not independently correlated with AKI incidence in patients with MI. Findings suggested that lower incidence of AKI seen in unmatched cohort patients treated with RA might be significantly influenced by confounding factors, particularly bleeding. Bleeding, heart failure, age ≥ 70 years, renal dysfunction on admission, and the contrast volume/GFR ratio were the predictors of AKI in the propensity-matched sample.
