Outcome of Patients With Prior Percutaneous Revascularization Undergoing Repeat Coronary Intervention (from the PRESTO Trial)

Patients with previous percutaneous coronary intervention (PCI) are often excluded from clinical trials. As a result, limited data are available on the long-term outcome of such patients undergoing repeat PCI. In this study, we assessed the impact of previous PCI on outcomes in patients undergoing repeat PCI. We compared the baseline features and outcomes of 7,056 patients without previous PCI (group I) with those of 1,281 patients with previous PCI of the original target lesion (group II) and 1,408 patients with previous PCI of a nontarget lesion (group III) undergoing PCI in the Prevention of Restenosis with Tranilast and its Outcomes (PRESTO) trial. Compared with patients in group I, patients in groups II and III were more likely to have diabetes (25% and 24% vs 21%, p
