Long-term outcome after drug-eluting stents implantation: Target lesion versus nontarget lesion repeated intervention

2010

Abstract We sought to investigate the relative clinical significance of target and nontarget lesions repeated percutaneous coronary intervention (re-PCI) in patients implanted with drug-eluting stents (DES). Out of 2626 consecutive DES patients, we retrospectively selected 166 (6.3%; 123 males, aged 65±10years) who had a clinically-driven re-PCI over a mean follow-up of 15months. Seventy-five patients (45%) underwent the second procedure for disease progression in nontarget lesions (nontarget lesion re-PCI group) while 91 (55%) showed target lesion in-stent restenosis or thrombosis (target lesion re-PCI group), with no significant intergroup difference in the temporal trends of re-PCI.
