Impact of instantaneous wave-free ratio on graft failure after coronary artery bypass graft surgery
International Journal of Cardiology(2021)
摘要
•No study to date has determined whether preoperative iFR is associated with graft patency after CABG.•The rate of graft failure is significantly higher when anastomosed on vessels with negative iFR than those with positive iFR.•The higher the preoperative iFR is, the more risk of graft failure within 1 year after CABG.
