ABSTRACT


BACKGROUND - Risk stratification after percutaneous coronary intervention (PCI) is mainly based on demographics and clinical presentation (stable coronary artery disease [CAD] vs. acute coronary syndromes [ACS]). We investigated the impact of PCI extent and complexity on 2-year clinical outcomes after successful implantation of drug-eluting stents (DES) and whether this effect is influenced by clinical presentation and/or high platelet reactivity (HPR) on clopidogrel.


METHODS AND RESULTS - Patients from the prospective, multicenter Assessment of Dual Antiplatelet Therapy with Drug-Eluting Stents study were stratified according to PCI complexity, with complex PCI (C-PCI) defined as ≥3 stents implanted, bifurcation PCI with 2 stents, rotational atherectomy use for severely calcified lesions, or left main or saphenous vein graft (SVG) PCI. Major adverse cardiac events (MACE; cardiac death, myocardial infarction, and stent thrombosis) were compared at 2-year follow-up in patients with and without C-PCI. Successful DES PCI was performed in 8582 patients-2255 (26.3%) with C-PCI. C-PCI was independently associated with higher 2-year risk of MACE (adjusted HR [adjHR]: 1.56; 95%CI: 1.29-1.89; p<0.0001), MI (adjHR: 1.71; 95%CI: 1.37-2.14; p<0.0001), and ST (adjHR: 2.26; 95%CI: 1.42-3.59; p=0.0006). The association between C-PCI vs. non-C-PCI and the risk of MI and ST was greater in stable CAD than in ACS (Pinteraction=0.04 and 0.03, respectively). SVG PCI, 2-stent bifurcation treatment, and implantation of ≥3 stents were independently associated with MACE.

CONCLUSIONS - Patients undergoing extensive and more complex PCI experienced worse outcomes after successful PCI. Considering the extent and complexity of PCI revascularization may improve risk stratification.
