The use of intraoperative transit time flow measurement can reduce preoperative myocardial injury

Abstract

patients undergoing off-pump coronary artery bypass grafting surgical procedures with general anesthesia were eligible. If they met one of the following criteria, patients were excluded: postoperative troponin did not reach normal value; combined with other valve surgery and significant liver dysfunction; died within 1 week after surgery. And after excluding 30 patients who did not meet the criteria, 146 patients were eventually included in the trial. In these studies, the postoperative myocardial injury was defined as an independent rise in cardiac troponin (from baseline) 70 times the upper reference limit (URL) according to ARC-2 criteria 10, regardless of the symptoms of ischemia and electrocardiogram changes, within this study, specifically 2380 ng/L.
