This study aims to investigate the impact of hepatic ischemia-reperfusion injury (HIRI) on the incidence of myocardial injury after non-cardiac surgery (MINS) and explore the potential underlying mechanisms. A bidirectional cohort study will be conducted, enrolling patients scheduled for major hepato-biliary surgery. Clinical data, perioperative parameters, and postoperative follow-up data will be systematically collected. The incidence of MINS between patients undergoing Pringle occlusion and portal vein occlusion will be compared, and a multivariate analysis will be performed to identify independent risk factors for MINS, providing a basis for early recognition and prevention of MINS.
