摘要

Abstract Objective This study investigates the relationship between the use of transit time flow measurement (TTFM) and postoperative myocardial injury in off‐pump coronary artery bypass grafting (OPCABG). Methods In this retrospective study, we collected basic data from patients hospitalized for OPCABG?in the Department of Cardiothoracic Surgery, Changzhou Second People's Hospital Affiliated with Nanjing Medical University. According to the academic research consortium (ARC)‐2 definition of significant myocardial injury, we used cardiac troponin I >2380?ng/L as a criterion for significant postoperative myocardial injury. We use logistic regression and forest plots to assess the association of TTFM use with myocardial injury outcomes. Results One hundred and forty‐six patients were included in this study. The overall median age of these patients was 65.05 years, and 32 (21.92) experienced a postoperative myocardial injury. TTFM was independently associated with the incidence of postoperative myocardial injury (odds ratio?=?0.34 95 confidence interval?=?0.15–0.78; p?=?.01), and we found similar trends in regression analyses across subgroups of sex, age, number of bridging vessels, hypertension, diabetes mellitus, BMI, and percutaneous coronary revascularization. One hundred and?six?patients were followed for 1‐year vessel permeability, and seven?patients (6.6) were occluded. Conclusions The use of TTFM is independently associated with a reduced incidence of postoperative myocardial lesions during off‐pump coronary bypass surgery. The TTFM procedure in OPCABG?deserves to be actively promoted to reduce the incidence of postoperative myocardial injury.
