Serum transaminase determined in the emergency room predicts outcomes in patients with acute ST-segment elevation myocardial infarction who undergo primary percutaneous coronary intervention.

Background: Elevated serum aspartate and alanine aminotransferase (AST and ALT) are often observed in patients with acute ST-segment elevation myocardial infarction (STEMI) and the condition is ascribed to liver hypoperfusion. We evaluated the prevalence and prognostic implication of hypoxic liver injury (HLI) in STEMI.

Methods: Patients with STEMI and no preexisting liver disease who underwent primary percutaneous coronary intervention (PCI) were enrolled.
