Background: High risk patients who undergo a non-cardiac surgery often develop a perioperative myocardial infarction (PMI).
Objective: To study the incidence of PMI among high risk patients who undergo preoperative evaluation for non-cardiac surgery by cardiologists.
Material And Method: This study was a cross-sectional study, performed at Thammasat Hospital for one year Eligible patients were subjects older than 40 years with pre-existing cardiovascular disease or with at least one major cardiovascular risk factor including chronic kidney disease who underwent non-cardiac surgery with preoperative cardiovascular evaluation. The primary outcome is perioperative myocardial infarction.
Results: Fifty-three patients (mean age 70.5 years, 54.7% female) were eligible for the study. Most of these patients underwent orthopedic surgery (24 patients, 45.3%) and general surgery (18 patients, 34%). Four female patients developed PMI, representing the incidence of 7.5 percent. Chronic kidney disease and peripheral arterial disease were statistically significant associated with PMI.
Conclusion: The incidence of PMI in this study was slightly higher than those reported in previous studies. Therefore, physicians should be aware of the diagnosis and proper management of this condition.

Development and validation of an EHR-based risk prediction model for geriatric patients undergoing urgent and emergency surgery.
BMC Anesthesiol

Kaiser Permanente Division of Research, 2000 Broadway, Oakland, CA, 94612, USA.
Background: Clinical determination of patients at high risk of poor surgical outcomes is complex and may be supported by clinical tools to summarize the patient's own personalized electronic health record (EHR) history and vitals data through predictive risk models. Since prior models were not readily available for EHR-integration, our objective was to develop and validate a risk stratification tool, named the Assessment of Geriatric Emergency Surgery (AGES) score, predicting risk of 30-day major postoperative complications in geriatric patients under consideration for urgent and emergency surgery using pre-surgical existing electronic health record (EHR) data.
Methods: Patients 65-years and older undergoing urgent or emergency non-cardiac surgery within 21 hospitals 2017-2021 were used to develop the model (randomly split: 80% training, 20% test).
Simultaneous transcatheter aortic valve implantation and femoral osteosynthesis: a case report.

Department of Anesthesiology, Japanese Red Cross Kumamoto Hospital, 2-1-1, Nagamine-Minami, Higashi-Ku, Kumamoto, 861-8520, Japan.
Background: Simultaneous cardiac and non-cardiac surgeries can be beneficial for patients, but there are still few reports on this approach.
Case Presentation: A 90-year-old woman was diagnosed with a femoral trochanteric fracture and severe aortic stenosis. A heart team conference decided to perform transcatheter aortic valve implantation (TAVI) and femoral osteosynthesis under general anesthesia on the same day.
Differences in Postoperative Disposition by Kidney Disease Severity: A Population-Based Cohort Study.

Department of Community Health Sciences, University of Calgary, Calgary, Alberta, CANADA; O'Brien Institute for Public Health, Cumming School of Medicine, University of Calgary, Calgary, Alberta, CANADA.
Rationale & Objective: People with advanced kidney disease undergo more non-cardiac operations compared to the general population, with a higher risk of perioperative cardiac events and death. However, little is known about the associations between severity of preoperative kidney dysfunction with postoperative length of hospitalization and discharge disposition; these were the focus of this study.

Association of Frailty with Intraoperative Complications in Older Patients Undergoing Elective Non-Cardiac Surgery.

Frailty is increasingly being recognized as a risk factor for adverse outcomes in older surgical patients undergoing surgery. We investigated the association between frailty and intraoperative complications using multiple frailty assessment tools in older patients undergoing elective intermediate- to high-risk non-cardiac surgery. This retrospective cohort study included 637 older patients scheduled for elective non-cardiac surgery.

Background: Blood loss resulting in severe anemia is the most common indication for postoperative allogenic red blood cell (RBC) transfusions. In high-income countries, the majority of transfusions is received by elderly patients. Preservatives extend the storage of RBCs, though concerns exist about potential harm from transfusing older RBCs.
