Exenatide Infusion During Heart Surgery Shows No Significant Benefits, Study Finds
TL;DR
The GLORIOUS trial found that intravenous exenatide did not significantly reduce risks during heart surgery, providing insights into cardiac surgery complexities.
Exenatide, a GLP-1 analog, was infused intravenously during heart surgeries, but no significant benefits were found in preventing complications.
While the trial did not show significant benefits, it provides important insights into cardiac surgery complexities, contributing to the pursuit of better patient outcomes.
The GLORIOUS trial found that intravenous infusion of exenatide during heart surgeries did not result in significant benefits, opening new areas for future research.

A major clinical trial has found that administering exenatide, a glucagon-like peptide-1 (GLP-1) analog medication, intravenously during heart surgeries involving cardiopulmonary bypass did not significantly reduce the risk of death, stroke, or organ failure. The findings, presented at the American Heart Association's Scientific Sessions 2024, challenge previous hopes that the medication might offer protective benefits during these complex procedures.
The GLORIOUS trial, conducted at a heart center in Denmark, involved approximately 1,400 adult patients undergoing coronary bypass grafting and/or surgical aortic valve replacement between 2016 and 2021. Participants were randomly assigned to receive either a six-hour and 15-minute infusion of exenatide or a placebo prior to surgery.
Results showed no significant differences in outcomes between the two groups over an average follow-up period of nearly six years. The mortality rate was 14% for the exenatide group versus 13% for the placebo group. Incidences of stroke, new or worsening heart failure, and acute kidney injury were also comparable between the two groups.
Dr. Sebastian Wiberg, the study's lead investigator, emphasized the importance of these findings, stating, "There is still a big gap in knowledge about how to best support patients on bypass during surgery, and there is an urgent need for more clinical trials to find ways to optimize patient health during and after bypass surgery."
While the results are disappointing, they provide valuable insights into the limitations of using GLP-1 analogs in this specific context. The study underscores the complexity of cardiac surgery and the challenges in developing interventions to reduce associated risks.
Experts caution that these findings may not be generalizable to other GLP-1 medications or different patient populations. Further research is needed to explore whether alternative GLP-1 analogs, longer administration periods, or higher doses could potentially yield benefits for patients undergoing cardiopulmonary bypass-assisted cardiac surgery.
The GLORIOUS trial's results highlight the critical need for continued research in perioperative care for cardiac surgery patients. As heart disease remains a leading cause of mortality worldwide, improving outcomes for those undergoing these life-saving procedures remains a top priority for medical researchers and clinicians alike.
