Model 1: crude. Model 2: adjusted for age, gender, COPD, PVD, CAD, history of stroke, rate-controlling medications, statins and eGFR. Model 3: adjusted for age, gender, BMI, preoperative haemoglobin, eGFR, CHF, hypertension, CAD, COPD, diabetes, history of stroke, PVD, rate-controlling medications, aspirin, statins, ASA classification, duration of anaesthesia, the highest intraoperative HMR, surgical procedures and intraoperative bleeding.
ASA, American Society of Anesthesiologist; BMI, body mass index; CAD, coronary arterial disease; CHF, congestive heart failure; COPD, chronic obstructive pulmonary disease; eGFR, estimated glomerular filtration rate; HMR, heart rate to mean arterial pressure; TyG index, triglyceride-glucose index; MINS, myocardial injury after non-cardiac surgery; PVD, peripheral vascular disease.
