Association of radial versus femoral access with contrast-induced acute kidney injury in patients undergoing primary percutaneous coronary intervention for ST-elevation myocardial infarction.

Background: Patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) are at an increased risk of developing contrast-induced acute kidney injury (CI-AKI). Data on the association between transradial (TRA) vs. transfemoral (TFA) access and the risk of CI-AKI in this setting are limited.
