Brief Summary:

The objective of this trial is to compare the clinical outcomes and cost-effectiveness of 2 therapeutic strategies, one based on coronary angiography guidance and the other based on coronary angiography with fractional flow reserve (FFR) in multivessel coronary artery disease patients.

The trial is a prospective, multicenter, French, randomized clinical trial including men and women ≥ 18 years presenting with significant multivessel disease defined by coronary angiography as coronary narrowing > 50% diameter stenosis in at least 2 major epicardic vessels. The patients who give their informed consent will be randomly assigned to a therapeutic strategy based upon coronary angiography or angiography with FFR testing. In the FFR group, a significant coronary stenosis will be defined by a FFR ≤ 0.8. Based upon this multivessel evaluation (angiography or FFR), the investigator will choose the best therapeutic strategy to his discretion (medical optimal treatment, coronary stenting, coronary artery bypass graft surgery). The aim of revascularization procedures will be to obtain complete revascularization. In the FFR group, only stenosis with FFR≤0.8 will be treated.

The primary end point of the trial is a composite of major cardiovascular events including death from any cause, myocardial infarction, any hospitalization for coronary revascularization performed in addition to initial treatment and stroke at 1 year of follow-up.

Secondary end points will include adverse events, individual major cardiovascular events, stent thrombosis, bleeding events, occlusion of coronary artery bypass graft, patient's quality of life and cost-effectiveness and 30-day, 6 month, 2-year and 5-year outcomes.

Arm Intervention/treatment

Patients will have FFR measured in each diseased vessel identified by the coronary angiographic evaluation. Intra-coronary adenosine (at least 100 micrograms performed 2 times) OR intravenous adenosine (at a dose of 140µg/kg/min during at least 4 minutes) will be administered prior to FFR assessment.

Revascularization strategy will be based upon FFR findings and revascularization either by coronary stenting or CABG will only be performed on target lesions with FFR≤0.8.

Procedure: invasive coronary angiography
Patients undergo an angiography. Based on angiographic evaluation, the physicians define the revascularization strategy.
Procedure: Functional testing by fractional flow reserve measurement
Functional testing by fractional flow reserve measurement

Primary Outcome Measures :
  1. composite endpoint that includes the rate of major cardiovascular events defined as a composite of death from any cause, myocardial infarction, any hospitalization leading to additional coronary revascularization, stroke. [ Time Frame: 1 year. ]
    The effect of therapeutic strategy will be assessed by the reduction of the incidence of major cardiovascular events in the group "angiography with FFR testing" in comparison to the group "angiography alone". Patients will be prospectively and clinically followed during the duration of the study and all major cardiovascular events will be documented and reported in the electronic case report form.

  2. Bypass graft patency assessed in all CABG patients at one year by coronary multidetector computed tomography . [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. Major cardiovascular events in all patients, in diabetic patients, by revascularization strategy (angioplasty, coronary artery bypass graft surgery, medical optimal treatment). [ Time Frame: 1 year ]
  2. The effect of our therapeutic strategy will be assessed upon each category of cardiovascular event individually. [ Time Frame: 1 year ]
  3. Major cardiovascular events in all patients. [ Time Frame: 2 years, 3 years, 4 years and 5 years ]
  4. Stent thrombosis. [ Time Frame: 1 year ]
  5. Bleeding events. [ Time Frame: 1 year ]
  6. Patient's quality of life [ Time Frame: 1 year ]
    We will use the European Quality of Life-5 Dimensions instrument.

  7. Cost-effectiveness of each therapeutic strategy [ Time Frame: 1 year ]
    NACost-effectiveness of each therapeutic strategy will be assessed by the evaluation of medical costs linked to the pathology (hospitalizations, consultations, and external medical costs (biology, radiology, medications) and compared in the 2 groups during the first 12 months of follow up.

  8. Bypass graft patency assessed in all CABG patients at one year by coronary multidetector computed tomography . [ Time Frame: 1 year ]
