Comparison of Propensity Score-Matched Analysis of Acute Kidney Injury After Percutaneous Coronary Intervention With Transradial Versus Transfemoral Approaches

摘要

Transradial percutaneous coronary intervention (TR-PCI) may be associated with reduced rates of acute kidney injury (AKI). There is limited data from real-world registries about AKI rates stratified by PCI access. Our aim was to evaluate AKI rates and correlates in TR-PCI versus transfemoral PCI (TF-PCI) in a propensity score matched analysis of patient data from a large, single-center registry. We performed a 1:1 propensity score matched analysis on consecutive patients who underwent PCI from January 2011 to June 2016, excluding those on dialysis. A multivariate logistic regression model was adjusted to variables found to be significant in univariate models. AKI was defined by creatinine increase of >= 0.3 mg/dL post-PCI during hospitalization. During the study period, 6,743 patients underwent PCI (TR-PCI n = 1,119). Initial univariate models revealed significant differences between patients with TF-PCI and TR-PCI. Contrast amount and procedure duration were both increased with TR-PCI versus TF-PCI (162 vs 154 ml, p = 0.003; and 86 vs 79 minutes, p <0.001, respectively). Multivariate propensity score analysis matched 536 pairs of patients. In this matched cohort, TR-PCI was associated with a reduced risk for AKI compared with TF-PCI in univariate (4.3% vs 10.4%, p <0.001) and multivariate adjusted models (odds ratio 0.28, 95% confidence interval 0.19 to 0.59, p <0.001).
