Intraoperative and Early Postoperative Risk Factors for the Development of Acute Cerebrovascular Accident in Elderly Patients after Coronary-Artery Bypass Grafting

This work presents data on the problem of ischemic heart disease, surgical myocardial revascularization, as well as the risk of developing acute cerebrovascular accident (ACVA) in elderly patients with coronary-artery bypass grafting (CABG). We conducted a study to identify risk factors for the development of ACVA in elderly patients. Predictors of ACVA development in the operative and early postoperative periods are identified. It is proven that the time of extubation, increased PCO₂ levels, and hyperlactatemia are reliable intraoperative and early postoperative predictors of ACVA in elderly patients with CABG. The practical significance of the study lies in the application of its results to predict the development of perioperative stroke in elderly patients with CABG.
