Objective: We evaluated 1-year outcomes after platinum chromium everolimus-eluting stents (PtCr-EES) in small versus non-small coronary arteries within a large, diverse sample of men, women, and minorities. Background: There exists limited outcomes data on the use of second-generation drug-eluting stent to treat small diameter coronary arteries. Methods: We pooled patients from the PLATINUM Diversity and PROMUS Element Plus stent registries. Small-vessel percutaneous coronary intervention (SV-PCI) was defined as ≥1 target lesion with reference vessel diameter (RVD) ≤2.5 mm. Endpoints included major adverse cardiac event (MACE; death, myocardial infarction [MI] or target vessel revascularization [TVR]), target vessel failure (TVF; death related to the target vessel, target vessel MI or TVR) and definite/probable stent thrombosis (ST). Multivariable Cox regression was used to risk-adjust outcomes. Results: We included 4,155/4,182 (99%) patients with available RVD, of which 1,607 (39%) underwent small-vessel PCI. SV-PCI was not associated with increased MACE (adjHR 1.02; 95%CI 0.81–1.30) or TVF (adjHR 1.07; 95%CI 0.82–1.39). MI risk was lower in white men compared to women and minorities, both in the setting of SV-PCI (adjHR 0.41; 95%CI 0.23–0.74 and adjHR 0.39; 95%CI 0.20–0.75, respectively) and for non-SV-PCI (adjHR 0.61; 95%CI 0.38–0.99 and adjHR 0.45; 95%CI 0.27–0.74, respectively). There was no significant interaction between RVD and sex or minority status for any endpoint. Conclusion: In a large diverse contemporary PCI outcomes database, SV-PCI with PtCr-EES was not associated with increased MACE or TVR and did not account for the increased MI risk noted in women and minorities compared to white men.
