Abstract 3047: What Are the Effects of Nonsteroidal Anti-Inflammatory Drugs on Post-Cardiothoracic Surgery Outcomes?
Background: Two previous studies evaluating nonsteroidal anti-inflammatory drug (NSAID) use following cardiothoracic surgery (CTS) demonstrated conflicting evidence regarding their ability to reduce the incidence of postoperative atrial fibrillation (POAF). Moreover, neither study examined negative cardiovascular outcomes such as stroke and myocardial infarction (MI). Since a recent study evaluating paracoxib/valdecoxib following CTS demonstrated an increased risk of cardiovascular events, we sought to evaluate whether NSAIDs could reduce the incidence of POAF without increasing patients’ risk of stroke or MI.
Methods: Patients (n=555) undergoing CTS from the randomized, controlled Atrial Fibrillation Suppression Trials (AFISTs) I, II and III were evaluated in this nested study. Demographic, surgical and medication use characteristics were prospectively collected as part of the AFIST trials. Endpoints included POAF, stroke, MI and the need for red blood cell transfusion. Multivariable logistic regression was used to calculate odds ratios with 95% confidence intervals.
Results: The population was 67.8 ± 8.6 years old, 77.1% male, 14.6% underwent valve surgery, 6.1% had prior AF, 12.6% had heart failure and 84.0% and 44.1% received postoperative beta-blockade and prophylactic amiodarone. In total, 127 (22.9%) patients received a NSAID postoperatively. NSAID use was associated with reductions in the odds of POAF and the need for RBC transfusions. (Table⇓) No elevation in the odds of developing stroke or MI was observed.
Conclusions: NSAIDs decreased the odds of developing POAF and the need for RBC transfusions without significantly increasing MI or stroke.
