The Impact of Preoperative Quantitative Flow Reserve (QFR) on Early Postoperative Radial Artery Graft Outcomes in Coronary Artery Bypass Grafting

NCT07669987 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 110

Last updated 2026-06-25

No results posted yet for this study

Summary

The goal of this observational study is to learn about the long-term effects of Quantitative Flow Reserve (QFR) assessment in patients undergoing Coronary Artery Bypass Grafting (CABG). The main question it aims to answer is:

Does preoperative QFR measurement improve graft outcomes and reduce major adverse cardiac and cerebrovascular events (MACE) in patients undergoing CABG?

Participants who are scheduled for CABG and have undergone preoperative QFR assessment will be followed for one year post-surgery. They will provide data on graft patency and report any occurrences of MACE through regular follow-up visits and questionnaires about their health status.
