Adjusted annualized rates of cardiovascular death and heart failure admission among patients referred for coronary angiography, by coronary flow reserve (CFR) and early revascularization strategy [coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or neither]. No difference in event rates was seen in patients with high CFR (orange, red, maroon), regardless of revascularization strategy pursued. In patients with low CFR, those who underwent CABG (dark blue) had lower event rates than those who underwent PCI (light blue, p=0.006) or no revascularization (green, p=0.001), and similar event rates to those with high CFR who underwent CABG (maroon). Annualized event rates were adjusted for pretest clinical score, left ventricular ejection fraction, left ventricular ischemia and coronary artery disease prognostic index.
