Abstract

    Background and aims: The long-term comparative results between culprit-only percutaneous coronary intervention (C-PCI) and multivessel PCI (M-PCI) or those between complete revascularization (CR) and incomplete revascularization (IR) in patients with non-ST-elevation myocardial infarction (NSTEMI) and multivessel disease (MVD) after successful newer-generation drug-eluting stent (DES) implantation are limited. Therefore, we compared the 2-year clinical outcomes in such patients.
    Methods: A total of 4588 patients with NSTEMI and MVD (C-PCI, n = 2055; M-PCI, n = 2533; CR, n = 2029; IR, n = 504) were evaluated. The primary outcome was major adverse cardiac events (MACEs) defined as all-cause death, recurrent myocardial infarction MI, and any repeat coronary revascularization. The secondary outcome was stent thrombosis (ST).
    Results: The cumulative incidences of the primary and secondary outcomes were similar in the three comparison groups (C-PCI vs. M-PCI, CR vs. IR, or CR vs. C-PCI). However, the cumulative incidence of non-target vessel revascularization (non-TVR) was higher in the C-PCI group than in the M-PCI group (adjusted hazard ratio [aHR]: 2.011; 95% confidence interval [CI]: 1.942-3.985; p = 0.012), higher in the IR group than in the CR group (aHR: 2.051; 95% CI: 1.216-4.183; p = 0.043), and higher in the C-PCI group than in the CR group (aHR: 2.099; 95% CI: 1.237-3.564; p = 0.006).
    Conclusions: Regarding the higher cumulative incidence of non-TVR, M-PCI and CR were preferred compared to C-PCI or IR in patients with NSTEMI and MVD. However, further randomized studies are required to confirm these findings.
