Predictors and Outcomes of Nonvariceal Upper Gastrointestinal Bleed After Coronary Artery Bypass Grafting: A Nationwide Analysis

BACKGROUND: Upper gastrointestinal bleeding is a severe postoperative complication after coronary artery bypass grafting. We aimed to identify the incidence, predictors, and outcomes of nonvariceal upper gastrointestinal bleeding (NVUGIB) readmissions within 30 days after coronary artery bypass grafting from a nationwide database. METHODS: ) and Procedure Coding System codes were used to identify the cohort. As the Nationwide Readmission Database is an anonymous public database, the study was exempt from the institutional review board. The analysis was conducted using Stata 17 (StataCorp LLC, College Station, TX). RESULTS: <0.001). CONCLUSIONS: NVUGIB readmissions after coronary artery bypass grafting are linked to significant morbidity and death. Early esophagogastroduodenoscopy is associated with improved outcomes, emphasizing its role in management.
