Introduction International guidelines recommend performing percutaneous coronary intervention (PCI) on stable coronary lesions with a positive fractional flow reserve (FFR) to improve clinical outcomes. It remains unclear if FFR positive lesions with preserved coronary flow reserved (CFR) might be better treated medically. Purpose This study compared clinical outcomes between PCI and medical therapy for stable FFR-positive lesions with preserved CFR. Methods We performed a substudy of the randomized, multicenter COMPARE-ACUTE trial in which treated ST-elevation myocardial infarction patients with stable non-culprit lesions were randomized to either FFR-guided PCI or medical therapy. Based on baseline and hyperaemic pressure gradients, we computed the so-called pressure bounded-CFR (pb-CFR) and classified lesions as low ( Results A total of 980 lesions from 885 subjects were included in this sub-study due to availability of baseline and hyperaemic pressure gradients. For the 462 lesions with FFR≤0.80, 249 had a pb-CFR Conclusions In this post-hoc substudy from a large randomized controlled trial of 885 subjects with 980 lesions, a preserved pb-CFR≥2 did not associate with an improved clinical outcome when FFR≤0.80. Subjects with FFR-positive coronary lesions but a preserved pb-CFR experienced significantly worse clinical outcomes when treated medically instead of with PCI. These data suggest that a stenosis with a FFR≤0.80, even when pb-CFR remains preserved, benefits from treatment with PCI.
