Risk Factors And Prognosis Of Gastrointestinal Hemorrhage With Myocardial Injury

ObjectiveMyocardial injury may be complicated with gastrointestinal bleeding(GIB)in patients.The purpose of this study was to investigate the risk factors of myocardial injury and the risk factors related to prognosis in patients with GIB,in order to improve the understanding of clinicians and to improve the prognosis of patients with GIB.MethodsA total of 219 patients with GIB admitted from January 1,2014 to December 31,2015 were collected retrospectively in the emergency department of a tertiary hospital.According to the diagnosis of myocardial injury,patients complicated with myocardial injury group and non-myocardial injury group were selected,then patients with myocardial injury group were selected and divided into survival group and death group,respectively.Demographic data,clinical characteristics,laboratory data,treatment outcomes,and other data of patients in different groups were first analyzed by univariate analysis,and then Logistic regression analysis was used to investigate possible risk factors for myocardial injury and risk factors related to prognosis in patients with GIB.ResultsOf 219 patients with GIB,160 patients had no myocardial injury and 59 patients had myocardial injury.Among them,age>65 years,coronary heart disease,heart failure,hemorrhagic shock,creatinine,albumin,lactic acid are risk factors for myocardial injury with GIB.Multivariate logistic regression analysis found that age>65 years,combined heart failure,hemorrhagic shock,and reduced albumin may be an independent risk factor for GIB associated myocardial injury.And multivariate Logistic regression analysis showed that the history of gastrointestinal surgery and elevation of RDW may be independent risk factors for in-hospital mortality for GIB complicated with myocardial injury.ConclusionGIB patients complicated with myocardial injury are more common in older age and are at higher risk of heart failure,hemorrhagic shock,and hypoalbuminemia.History of digestive tract surgery and elevated RDW may be independent risk factors for death in patients with GIB complicated with myocardial injury.
