Brief Summary

In coronary artery bypass grafting (CABG), the use of radial artery (RA) is recommended by the guidelines only to significantly stenosed vessel, due to its high vulnerability to competitive flow. Fractional flow reserve (FFR) is the gold standard to measure physiological significance of coronary lesions and the potential for competitive flow. This study aims to investigate whether the preoperative quantitative flow ratio (QFR) measurement, a novel coronary angiography-based FFR, is associated with RA graft failure post-CABG, and to explore the best cut-off value of QFR for RA grafts using. Patients from ASRAB-pilot trial (NCT04310995) undergoing primary isolated CABG using RA grafts, and with preoperative coronary angiography (CAG) images available for QFR analysis will be enrolled in this prospective double-blind observational study. QFR analysis will be conducted for all RA-grafted vessels based on preoperative CAG. The primary outcome will RA graft failure (FitzGibbon Grade B,O or S) evaluated by coronary computer tomography angiography or CAG at 7 days and 6 months post-CABG.

Outcome Measures

Primary Outcomes (2)

  • 6-month radial artery graft failure

    Graft outcome will be evaluated by CCTA or CAG according to the Fitzgibbon classification criteria: Grade A, grade B, grade O and grade S (String Sign). Grade B, O and S are considered as graft failure.

    6 months after surgery

  • 7-day radial artery graft failure

    Graft outcome will be evaluated by CCTA or CAG according to the Fitzgibbon classification criteria: Grade A, grade B, grade O and grade S (String Sign). Grade B, O and S are considered as graft failure.

    7 days after surgery

Secondary Outcomes (3)

  • Major adverse cardiovascular event (MACE)

    within 6 months after surgery

  • Myocardial infarction related to radial artery graft failure

    within 6 months after surgery

  • Unplanned coronary revascularization related to radial artery graft failure

    within 6 months after surgery

Study Arms (2)

QFR-Low Group

Based on preoperative CAG, QFR analysis will be conducted for vessels bypassed with RA grafts. The RA-grafted vessels with QFR below the best cut-off value (0.50-0.55 assumed) will be allocated to QFR-Low group.

QFR-High Group

Based on preoperative CAG, QFR analysis will be conducted for vessels bypassed with RA grafts. The RA-grafted vessels with QFR over the best cut-off value (0.50-0.55 assumed) will be allocated to QFR-High group.
