Abstract
Objective
The objective of this study was to identify patient characteristics associated with acute kidney injury (AKI) post-coronary angiography with or without percutaneous coronary intervention.
Methods
This retrospective, single-center study analyzed 350 patients from October 1, 2017 to September 30, 2018. The primary endpoint was AKI, defined as a rise in creatinine >0.3 mg/dL within 48 hours of coronary angiography.
Results
AKI occurred in 41 of 350 patients (8.8%). Patients experiencing AKI had a higher incidence of hypertension (100%; P = 0.005), hyperlipidemia (98%; P = 0.001), diabetes mellitus (68%; P = 0.0005), and heart failure (37%; P = 0.0057). AKI occurred in 30 of 185 (16%) and 11 of 165 (6.7%) patients undergoing femoral and radial access, respectively. AKI incidence was not significantly affected by contrast dose (99 ± 9 vs 93 ± 3 mL; P = 0.52), fluoroscopy time (10.3 min [IQR 6.3, 17.7] vs 8.5 min [IQR 4.5, 13.9]; P = 0.2), or preprocedural computed tomography with contrast (P = 0.66). Multivariable regression showed significantly higher AKI among patients with peripheral artery disease (odds ratio [OR] = 12.4; 95% confidence interval [CI] 3.4–33.6; P = 0.0001), multivessel coronary artery disease (OR = 11.9; 95% CI 2.3–61.1; P = 0.003), and initial creatinine >1.5 mg/dL (OR = 4.4; 95% CI 1.4–13.6; P = 0.01).
Conclusion
Peripheral artery disease, multivessel disease, and creatinine >1.5 mg/dL were associated with a higher risk of AKI in patients undergoing coronary angiography in this single-center retrospective cohort.
