Abstract

Background and purpose: Gastrointestinal bleeding is an important complication in the acute phase of hemorrhagic stroke. In this study, we aimed to identify the risk factors for gastrointestinal bleeding in patients with hemorrhagic stroke despite the administration of antiulcer drugs.

Methods: We conducted a retrospective cohort study of our hemorrhagic stroke cases. We analyzed the background factors associated with gastrointestinal bleeding in the study population and their outcomes.

Results: The study included 837 patients: 598 with intracerebral hemorrhages and 239 with subarachnoid hemorrhages. Among them, 22 patients developed gastrointestinal bleeding. Intraventricular hemorrhage (P=0.0019) and ongoing oral anticoagulant use (P=0.0177) were significantly associated with gastrointestinal bleeding. Gastrointestinal bleeding was significantly associated with severe disability at discharge (P=0.0333) and number of days of hospitalization (P=0.0190).

Conclusions: The risk factors of poorly controlled gastrointestinal bleeding during the acute phase of hemorrhagic strokes were intraventricular hemorrhage and use of anticoagulant drugs. Patients with a high risk for gastrointestinal bleeding need to be identified and to be given effective prophylactic therapy.
