Factors affecting the occurrence of gastrointestinal bleeding in acute ischemic stroke patients

Abstract

Gastrointestinal bleeding (GIB) is a common complication that occurs after stroke, and GIB may negatively affect patient prognosis. In this study, we aimed to examine:(1) the risk factors of GIB in acute cerebral infarction patients;(2) association between GIB and 1-year mortality in patients with acute cerebral infarction.Patients with acute cerebral infarction were divided into 2 groups based on the occurrence of GIB during acute stroke stage. Patient characteristics, clinical presentation, stroke risk factors, comorbidities, laboratory data, medication, and outcomes were investigated to analyze the associations between the variables and the probability of having GIB. In addition, patients in the study were matched individually by age, gender. A 1:1 matched case-control method and conditional logistic regression models for single and multiple factors were used to assess the risk factors of GIB in acute cerebral infarction patients.Clinical data of patients with acute cerebral infarction were reviewed and analyzed during the years 2015 and 2016. Finally, 1662 patients with acute cerebral infarction were included in this study, of whom 139 (8.5%) patients had GIB at admission. Multivariate logistic regression analysis revealed that the independent risk factors for GIB in patients with acute cerebral infarction were advanced age (OR=1.030, P=.009), low Glasgow Coma Scale (GSC) score (OR=0.850, P=.014), infection (OR=4.693, P
