Background: Acute kidney injury (AKI) is common after cardiac
interventional procedures. The prevalence and clinical outcome of AKI in patients
with acute myocardial infarction (AMI) after undergoing intra-aortic balloon pump
(IABP) implantation remains unknown. The aim of this study was to investigate the
incidence, risk factors, and prognosis of AKI in specific patient populations.
Methods: We retrospectively reviewed 319 patients with AMI between
January 2017 and December 2021 and who had successfully received IABP
implantation. The diagnostic and staging criteria used for AKI were based on
guidelines from “Kidney Disease Improving Global Outcomes”. The composite
endpoint included all-cause mortality, recurrent myocardial infarction,
rehospitalization for heart failure, and target vessel revascularization.
Results: A total of 139 patients (43.6%) developed AKI after receiving
IABP implantation. These patients showed a higher incidence of major adverse
cardiovascular events (hazard ratio [HR]: 1.55, 95% confidence interval [CI]:
1.06–2.26, p = 0.022) and an increased risk of all-cause mortality (HR:
1.62, 95% CI: 1.07–2.44, p = 0.019). Multivariable regression models
found that antibiotic use (odds ratio [OR]: 2.07, 95% CI: 1.14–3.74, p
= 0.016), duration of IABP use (OR: 1.24, 95% CI: 1.11–1.39, p
