BACKGROUND: Use of antiplatelet agents (APAs) have been shown to increase the risk of gastrointestinal (GI) bleeding despite their cardiovascular benefits. AIM: To understand the impact of APAs, we assessed the outcomes in patients admitted with acute GI bleeding to our hospital. We hypothesized there is no difference among GI bleeders admitted to the hospital while bleeding on or off APAs. METHODS: In an observational prospective cohort study, 104 sequential patients admitted with a diagnosis of GI bleeding were followed. Patients were classified as either on APA or not. RESULTS: Thirty of 104 (29%) patients were on long-term aspirin and/or clopidogrel on admission and 5 were taking nonaspirin nonsteroidal anti-inflammatory drugs, total of 35 (34%). There was no difference between patients using APA and those not using APA with regard to admission hemoglobin, age, presentation, source of bleed, total number of units transfused, intensive care unit admission rates, and overall length of stay. There was, however, a significant difference in the presence of hemodynamic compromise on initial presentation, with a higher proportion of APA users being orthostatic (51.4% vs 26% in nonusers, with P=0.02, by Fisher exact test). Clopidogrel was safely restarted in high-risk patients with significant cardiac history. CONCLUSIONS: This study demonstrated that APA use did not significantly alter the course or outcome in GI bleeders admitted to our institution during their hospital stay.
