Cardiac troponin (cTn) is a type of protein found in the heart muscles. It is released into the bloodstream when heart muscles become damaged. However, cTn can also be elevated in patients with non-cardiac illnesses, such as critically ill patients and patients with acute gastrointestinal bleeding (AGIB). This study analyzed the relationship between elevated cTn and the outcomes (including prevalence, predictors and mortality) in patients with AGIB. A total of 172 patients with AGIB were evaluated. They were divided into groups based on the presence of elevated cTn. The prevalence of elevated cTn in AGIB patients was 17%. Older age, lower BMI, coronary artery disease and chronic kidney disease were found to be some of the factors that can predict cTn elevation in AGIB patients. AGIB patients with elevated cTn had more cardiology service consultations and procedures and longer lengths of hospital stay. However, there was no effect of elevated cTn on the death rate of AGIB patients.
