Acute kidney injury in patients with myocardial infarction undergoing percutaneous coronary intervention using radial versus femoral access.

The access site was not independently associated with the incidence of AKI in patients with MI in both a non-matched and a propensity-matched cohort. Our study result suggests that the lower incidence of AKI in patients treated with RA in an unmatched cohort might be substantially influenced by confounding factors, especially bleeding.
