A prospective randomized comparison between paclitaxel and sirolimus stents in the real world of interventional cardiology: the TAXi trial

OBJECTIVES: We conducted this trial to assess whether a sirolimus-eluting stent (SES) produces similar results to a paclitaxel-eluting stent (PES) when used in the real world of interventional cardiology. BACKGROUND: Several drug-eluting stents have been shown to exert a beneficial effect on restenosis when used in the treatment of coronary artery disease. Any potential superiority of one drug over the others, however, is still unknown. METHODS: To evaluate whether a PES or an SES is superior in daily practice, we randomized all patients suitable to receive a drug-eluting stent in our institution. Clinical follow-up was obtained after at least six months. RESULTS: A total of 202 patients were included in this trial. One hundred patients received a PES and 102 received an SES. Procedural success was 99% in both groups. Incidence of major adverse cardiac events at follow-up (mean 7 +/- 2 months) was 4% with the PES and 6% with the SES (p = 0.8). The need for target lesion revascularization was very low in both groups (1% with the PES and 3% with the SES). CONCLUSIONS: Our results confirm that the high success rate obtained with both stents in randomized trials can be replicated in routine clinical practice. In this small group of patients we were unable to show any advantage of one stent over the other.
