Risk factors for gastrointestinal bleeding in patients with intracerebral hemorrhage: A propensity score matching analysis

Background: Gastrointestinal bleeding (GIB) is a common complication of intracerebral hemorrhage (ICH). Rate pressure product (RPP) is an objective hemodynamic index that is closely related to the prognosis of cardiacerebrovascular disease. The purpose of this study was to investigate the relationship between RPP and GIB in ICH patients. Methods: We retrospectively analyzed data from ICH patients admitted to the neurosurgery department of Nanchang University affiliated with Ganzhou Hospital from January 2019 to December 2021. The patients were divided into a GIB group and a non-GIB group according to whether they had GIB. Propensity score matching was used to match between the two groups. Univariate analysis was used to select factors affecting GIB, and multivariate conditional logistic regression was used to analyze the independent factors associated with GIB. Results: There were 1232 patients included in the study, including 182 in the GIB group and 1050 in the non-GIB group, and 182 pairs of patients were successfully matched through propensity score matching. The univariate analysis showed that high RPP, low Glasgow coma score (GCS), fibrinogen, D-dimer and PPIs were factors associated with GIB. Multivariate conditional logistic regression showed that high RPP, low GCS and urokinase were independent risk factors for GIB, and PPIs was a protective factor for GIB. Conclusions: High RPP, low GCS and urokinase were independent risk factors for GIB, and PPIs was a protective factor for GIB. Patients with a high risk of developing GIB should be monitored closely. Nevertheless, multicenter prospective studies with more patients are needed to further validate the results.
