Association Between μFR And CABG Outcomes

Association Between Murray Law-Based Angiography-Derived Fractional Flow Reserve and Outcomes After Coronary Artery Bypass Grafting

The goal of this observational study is to evaluate the association between Murray law-based quantitative flow reserve and outcomes after coronary artery bypass graft surgery.

The goal of this observational study is to evaluate the association between Murray law-based quantitative flow reserve and outcomes after coronary artery bypass graft surgery. By constructing registry database during 10-year periods, several types of study objectives including 'graft patency' and 'long-term clinical outcomes' will be evaluated.

Inclusion Criteria:

1. patients who underwent isolated off-pump CABG for 3-vessel disease,
2. patients who underwent preoperative coronary angiography that fits for μFR analysis,

Exclusion Criteria:

1. Patients who underwent on-pump CABG
2. Patients in whom quality of preoperative coronary angiography did not fit for μFR analysis
