Risk factors, prediction model, and prognosis analysis of myocardial injury after acute upper gastrointestinal bleeding.

Background: Cardiovascular complications in patients with acute upper gastrointestinal bleeding (AUGIB) have been associated with a high-risk of subsequent adverse consequences. This study aimed to analyze the risk factors for myocardial injury in AUGIB patients, predict the risk of myocardial injury, and explore the clinical prognosis and influencing factors in AUGIB patients with myocardial injury.

Materials And Methods: A retrospective case-control study based on AUGIB patients in the First Affiliated Hospital of Xi'an Jiaotong University from 2016 to 2020 was performed.

Clinical characteristics and risk factors of in-hospital gastrointestinal bleeding in patients with acute myocardial infarction.

Background: Gastrointestinal bleeding (GIB) is one of the most serious complications of acute myocardial infarction (AMI) and is correlated with poor outcomes.

Objective: To evaluate the prevalence, risk factors and in-hospital mortality of GIB in patients with AMI.

Methods: This observational case-control study retrospectively enrolled consecutive patients with AMI from the Department of Cardiovascular Medicine and Cardiovascular Surgery of the First Affiliated Hospital of Xi'an Jiaotong University from January 2015 to December 2020.
