    BackgroundTemporal trends and risk factors of perioperative cardiac events (PCEs) in patients over 80 years old with coronary artery disease (CAD) undergoing noncardiac surgery are still unclear.MethodsWe retrospectively reviewed 1478 patients over 80 years old, with known CAD undergoing selective noncardiac surgery in a single center (2014-2022). Patients were divided into three equal time groups based on the discharge date (2014-2016, 2017-2019, and 2020-2022), with 367, 473, and 638 patients in Groups 1-3, respectively. Perioperative clinical variables were extracted from the electronic medical records database. The primary outcome was the occurrence of PCEs intraoperatively or during hospitalization postoperatively, defined as any of the following events: myocardial infarction, heart failure, nonfatal cardiac arrest, and death.ResultsPCEs occurred in 180 (12.2%) patients. Eight independent risk factors were associated with PCEs, including four clinical factors (body mass index < 22 kg/m2, history of myocardial infarction, history of heart failure, and general anesthesia) and four preoperative laboratory results (hemoglobin < 110 g/L, albumin < 40 g/L, creatinine > 120 μmol/L, and potassium <3.6 mmol/L). Significant rising trends were seen over the 9-year study period in the incidence of PCEs and independent risk factors including history of myocardial infarction, history of heart failure, general anesthesia, preoperative hemoglobin < 110 g/L, preoperative albumin < 40 g/L, and preoperative creatinine > 120 μmol/L (P for trend <0.05).ConclusionThe incidence and independent risk factors of PCEs in patients over 80 years old with CAD undergoing noncardiac surgery showed significant rising trends over the last 9-year period.© The Author(s) 2024.
