Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Rate of residual ischemia defined as iFR | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary clinical endpoints: 1. Composite of cardiac death, target vessel myocardial infarction, ischemia-driven target vessel revascularization or recurrent ischemia at one year (definition below) 2. Target vessel failure defined as cardiac death, target vessel myocardial infarction, ischemia-driven target vessel revascularization 3. Quality of life (assessed by the Seattle Angina Questionnaire) at baseline, 30-days, 6 months and 1year 4. All-cause and cardiac mortality at one year 5. Target vessel Myocardial infarction at one year 6. Ischemia-driven target vessel revascularization at one year 7. Recurrent ischemia at one-year Secondary physiology endpoints: 8. Correlation between iFR 50% assessed by visual interpretation 9. Proportion of cases in which the iFR would become non-significant if a focal stenosis demonstrated by iFR pullback were treated with PCI 10. Differentiation of the cause for impaired iFR (categorized as stent related, distant focal stenosis, or diffuse atherosclerosis) 11. Predictors of delta iFR before and after PCI | — |
