Gastrointestinal bleeding in patients admitted to cardiology: risk factors and a new risk score

Although the early use of a risk stratification score in gastrointestinal bleeding (GIB) is recommended, so far there has been no for GIB patients admitted to cardiology department. To describe factors and develop new model A total 633 inpatients with from January 2014 December 2018 were recruited, 4,231 non-GIB recruited as control group. Multivariate logistic regression was used GIB. developed derivation cohort. Accuracy predict assessed by area under receiver operating characteristic (AUROC) curve validation Male, coronary heart disease, hypertension, stroke, systolic blood pressure, hematocrit, plasma albumin, alanine aminotransferase (ALT) associated The had high predictive accuracy (AUROC 0.816 95% CI, 0.792-0.839), which supported cohort 0.841 0.807~0.874). Besides, prediction better than HAS-BLED 0.557; 0.513~0.602) CRUSADE 0.791; 95%CI, 0.757~0.825), respectively. Among 0-3, 4-7, ≥8 points, incidence GIB, proportion requiring suspended red cells transfusion, length stay, in-hospital mortality all increased gradually (P< 0.001). ALT are an accurate that predicts
