ObjectiveTo document the association between serum transaminases and in-hospital mortality in pulmonary embolism (PE) patients.Study DesignAnalytical study.Place And Duration Of StudyPatients treated with acute PE in hospital between January 2011 and December 2019 from Sakarya University Medical School Research and Teaching Hospital, Sakarya, Turkey.MethodologyPatients with PE were included. Receiver operating characteristics (ROC) analysis was conducted to define a cut-off value for AST/ALT ratio to predict in-hospital death. Simplified pulmonary embolism severity index (sPESI) scores were calculated and the AST/ALT ratio were entered into binary logistic regression analysis with components of sPESI score to document the prognostic significance of as an independent predictor of in-hospital mortality.Results164 acute PE patients were included; of those, 33 (20%) died in hospital. Deceased patients had higher AST/ALT ratio (median, 1.4; 25th-75th percentile, 1.1-1.8) comparing to patients with discharged home (median, 1.1; 25th-75th percentile, 0.84-1.4) (p=0.006). ROC analysis showed that AST/ALT ratio was an indicator of in-hospital mortality, and the calculated area under the curve was 0.655 (95% CI, 0.547-0.764). The cut-off value of 1.3 was associated with a prognostic sensitivity of 61% and specificity of 65%. Binary logistic regression analysis failed to show AST/ALT ratio as an independent predictor of in-hospital mortality.ConclusionAST/ALT ratio predicts in-hospital mortality with acceptable sensitivity and specificity in patients with acute PE and might be used as a biomarker for risk stratification. Key Words: Pulmonary embolism, In-hospital mortality, Transaminases.
