Abstract

Non-variceal upper gastrointestinal bleeding (NVUGIB) in non-ST-elevation myocardial infarction (NSTEMI) is associated with substantial morbidity and mortality. We evaluated inpatient outcomes of esophagogastroduodenoscopy (EGD) before cardiac catheterization in patients with NSTEMI and NVUGIB. We utilized the National Readmission Database (2016-2019) to identify all index hospitalizations with a primary diagnosis of NSTEMI and a secondary diagnosis of NVUGIB that underwent EGD before cardiac catheterization (cases). A matched comparison cohort of similar hospitalizations that undergo EGD after cardiac catheterization were identified (controls) after 1:1 propensity score matching for age, gender, cardiac comorbidities, causes, and severity of bleeding. A total of 796 cases were matched with 796 controls. There was a higher median length of hospital stay (8 vs. 5days, P = 0.01) and median hospital charges ($111,218 vs. $99,115, P = 0.002) for cases compared to controls. There was a higher all-cause inpatient mortality in cases compared to controls (5.5% vs. 3.9%, P = 0.26). Furthermore, there was a higher proportion of patients with ICU admission (7% vs. 3%, P < 0.001), septic shock (7.1% vs. 5.8%, P = 0.41), atrial fibrillation (27.1% vs. 19.8%, P < 0.001) and acute kidney injury (42.8% vs. 29.1%, P < 0.001) for cases compared to controls. Delaying cardiac catheterization in favor of EGD is associated with increased hospital stay, costs, and cardiac complications. Further studies are warranted to establish our findings.
