Abstract

INTRODUCTION: Preoperative congestive heart failure (CHF) is associated with higher postoperative mortality and complications in noncardiac surgery. However, postoperative outcomes for patients with preoperative CHF undergoing endovascular aneurysm repair (EVAR) have not been thoroughly established. This study evaluated the effect of preoperative CHF on 30-day outcomes following nonemergent intact EVAR using a large-scale national registry. METHODS: Patients who had infrarenal EVAR were identified in the ACS-NSQIP database from 2012 to 2022. A 1:5 propensity-score matching was used to match demographics, baseline characteristics, aneurysm diameter, distant aneurysm extent, anesthesia, and concomitant procedures between patients with and without preoperative CHF. Thirty-day postoperative outcomes were examined. RESULTS: 467 (2.84%) CHF patients underwent intact EVAR. Meanwhile, 15,996 non-CHF patients underwent EVAR, where 2,248 of them were matched to all CHF patients. Patients with and without preoperative CHF had comparable 30-day mortality (3.02% vs. 2.62%, p = 0.64). However, CHF patients had higher myocardial infarction (3.02% vs. 1.47%, p = 0.03), pneumonia (3.23% vs. 1.73%, p = 0.04), 30-day readmission (p = 0.01), and longer length of stay (p < 0.01). CONCLUSION: While patients with and without preoperative CHF had comparable 30-day mortality rates, those with CHF faced higher risks of cardiopulmonary complications. Effective management of preoperative CHF may help prevent postoperative complications in these patients.
