Arm Description
This group will be performed a CABG surgery based on CAG and QFR, whether graft the moderate stenosis vessels will be based on the result of QFR.
This group will be performed a CABG surgery only based on CAG, the final surgery strategy will be decided after the discussion of heart team.
Outcomes
Primary Outcome Measures
The rate of graft patency
graft patency will be evaluated by CTA, 2 doctors will be invited to read the CT and draw their own conclusion without knowing the other result
Secondary Outcome Measures
Major adverse cardiovascular event(MACE)
The rate of deaths due to cardiovascular events, myocardial infarction and second revascularization
The rate of angina relief
whether angina is relieved will be evaluated

5. Study Description
Brief Summary
Coronary artery bypass grafting(CABG) is the golden standard for severe coronary artery disease(CAD), the current surgery strategy is mainly based on coronary angiography(CAG), but many trials of PCI have shown that visually stenosis in CAG may not have functional significance. The aim of this study is to investigate if the Quantitative Flow Ratio (QFR) can be adopted in CABG and achieve a better graft patency.
Detailed Description
CABG is the major treatment of three vessels or left main disease. CAG is the main basis on choosing the vessels to graft, however, some of the grafts occluded shortly after surgery due to competitive flow, these vessels may not be significantly stenosis in functional assessment such as Fractional Flow Reserve (FFR). Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. Comparing to FFR, there is no need for pressure wire or ATP when performing QFR. This study plan to investigate the clinical effect of QFR in CABG, all patients included will be allocated 1:1 into two groups: QFR-guided and Angio-guided, QFR-guided group will be performed a CABG based on the result of QFR, the other group will be based on heart team discussion of CAG, CTA will be adopted to evaluate the 1 year graft patency.
