Abstract

Abstract : Background: Patients with prior percutaneous coronary intervention (PCI) are at high residual risk for multiple types of coronary events within and beyond the stented lesion. This risk might be mitigated by more intensive LDL-C (low-density lipoprotein cholesterol)-lowering beyond just with statin therapy. Methods: FOURIER (Further Cardiovascular Outcomes Research With PCSK9 Inhibition in Subjects With Elevated Risk) randomized 27 564 patients with stable atherosclerotic disease on statin to the PCSK9 (proprotein convertase subtilisin-kexin type 9) inhibitor evolocumab or placebo with a median follow-up of 2.2 years. The end points of interest were major adverse cardiovascular events (MACE; a composite of cardiovascular death, myocardial infarction, stroke, unstable angina or coronary revascularization), and major coronary events (a composite of coronary heart death, myocardial infarction, or coronary revascularization). We compared the risk of MACE and the magnitude of relative and absolute risk reductions with evolocumab in patients with and without prior PCI. Results: Seventeen thousand seventy-three patients had prior PCI. In the placebo arm, those with prior PCI had higher rates of MACE (13.2% versus 8.3%; hazard ratio [HR]adj 1.61 [95% CI, 1.42–1.84]; P <0.0001) and major coronary events (11.5% versus 6.0%; HRadj, 1.72 [95% CI, 1.49–1.99]; P <0.0001). Relative risk reductions with evolocumab were similar in patients with and without prior PCI (MACE: HR, 0.84 [0.77–0.91] versus HR, 0.88 [0.77–1.01]; P interaction 0.51; major coronary events: HR, 0.82 [0.75–0.90] versus HR, 0.88 [0.75–1.04]; P interaction 0.42). Absolute risk reductions for MACE were 2.0% versus 0.9% ( P interaction 0.14) and for major coronary events 2.0% versus 0.7% ( P interaction 0.045). In those with prior PCI, the effect of evolocumab on coronary revascularization (HR, 0.76 [0.69–0.85]) was directionally consistent across types of revascularization procedures: coronary artery bypass grafting (HR, 0.71 [0.54–0.94]); any PCI (HR, 0.77 [0.69–0.86]); PCI for de novo lesions (HR, 0.76 [0.66–0.88]); and PCI for stent failure or graft lesions (HR, 0.76 [0.63–0.91]). Conclusions: Evolocumab reduces the risk of MACE in patients with prior PCI including the risk of coronary revascularization, with directionally consistent effects across several types of revascularization procedures, including coronary artery bypass grafting and PCI for stent or graft failure.
