In drug-eluting stent restenosis, the contribution of drug hypo-responsiveness is poorly defined. We pooled data from the ISAR-DESIRE and ISAR-DESIRE 2 randomized trials and analyzed outcomes in SES-treated and PES-treated patients. In SES-treated patients, both late loss and percentage diameter stenosis were lower in patients treated for bare metal stent restenosis compared with SES restenosis. By contrast in PES-treated patients, outcomes were similar in patients treated for patients with bare metal stent restenosis and SES restenosis. The relatively lower efficacy of SES in SES in-stent restenosis may support a role for hypo-responsiveness to sirolimus in these patients.
