Elevated cardiac troponin T in cirrhotic patients with emergency care admissions: Associations with mortality

BACKGROUND AND AIM Mortality of cirrhotic patients after emergency care admission is high, and prognostic factors can help in prioritizing patients. The aim of our study was to assess the association between levels of cardiac troponin T (cTnT) and 1-year mortality in patients with liver cirrhosis without known cardiac disease, who were admitted to the emergency department (ED). METHODS All patients with cirrhosis presented to the ED from October 2009 until August 2015 who had an initial cTnT value measured with the first lab panel were retrospectively analyzed with a follow-up of 365 days. RESULTS Of a total of 237 cirrhotic ED patients, cTnT measurements were available for 87 (63% men, mean age 58.9 ± 11.0 years, and median Model for End-stage Liver Disease score was 15 [25th-75th percentile: 10-19]). Chronic Liver Failure Consortium acute-on-chronic liver failure (CLIF-C-ACLF) score was 33. Forty-three patients (49%) had cTnT values above the normal range (14 ng/L), of which 19 (22%) had values over 30 ng/L. Two patients were lost to follow-up. In multivariable analysis, both CLIF-C-ACLF (hazard ratio 1.072 per point increase; 95% confidence interval 1.029-1.117; P
