Long-term (three-year) safety and efficacy of everolimus-eluting stents compared to paclitaxel-eluting stents (from the SPIRIT III Trial).

The safety and efficacy of the XIENCE V everolimus-eluting stent (EES) compared to the Taxus Express(2) paclitaxel-eluting stent (PES) has been demonstrated through 2 years in the SPIRIT II and III randomized clinical trials, but limited longer-term data have been reported. In the SPIRIT III trial, 1,002 patients with up to 2 lesions in 2 coronary arteries were randomized 2:1 to EESs versus PESs at 65 United States sites. At completion of 3-year follow-up, treatment with EES compared to PES resulted in a significant 30% decrease in the primary clinical end point of target vessel failure (cardiac death, myocardial infarction, or ischemic-driven target vessel revascularization, 13.

Comparison of everolimus-eluting and paclitaxel-eluting coronary stents in patients with two treated vessels: 2-year results from the SPIRIT III randomised trial.

Aims: To examine the two year clinical outcomes in dual-vessel disease from the SPIRIT III trial comparing the XIENCE V(r) everolimus-eluting stent (EES) to the TAXUS Express2(tm) paclitaxel-eluting stent (PES).

Methods And Results: From a total of 1,002 randomised subjects, 103 and 51 patients in the EES and PES groups respectively underwent stenting of two lesions in two vessels (one lesion per epicardial vessel). Two-year event rates were lower in one compared to two-vessel treated patients regardless of stent type.

Evaluation of the effects of everolimus-eluting and paclitaxel-eluting stents on target lesions with jailed side branches: 2-year results from the SPIRIT III randomized trial.

Objective: To evaluate whether an everolimus-eluting stent (EES) with thinner stent struts and polymer results in less periprocedural myonecrosis and adverse outcomes.

Background: Higher periprocedural myocardial infarction (MI) rates have been reported with the TAXUS® EXPRESS(2) paclitaxel-eluting stent (PES) compared to the bare metal EXPRESS(2)® stent due to more frequent side branch compromise, presumably attributable to the thickness of the stent/polymer on the PES.

Methods: In the SPIRIT III trial, we identified 113 patients in the XIENCE V® EES group and 63 patients in the TAXUS EXPRESS(2) PES group who met the criteria of having a lesion with a jailed side branch (<2 mm diameter, and <50% stenosis).

Everolimus-eluting versus paclitaxel-eluting stents in coronary artery disease.

Background: Previous studies have established the superiority of coronary everolimus-eluting stents over paclitaxel-eluting stents with respect to angiographic findings. However, these trials were not powered for superiority in clinical end points.

Methods: We randomly assigned 3687 patients at 66 U.

Randomized comparison of everolimus- and paclitaxel-eluting stents: pooled analysis of the 2-year clinical follow-up from the SPIRIT II and III trials.

Aims: To investigate the clinical impact of the following observations in the randomized SPIRIT II and III trials: an incremental increase in in-stent neointima between 1 and 2 years with the everolimus-eluting stent (EES) but not with the paclitaxel-eluting stent (PES) in SPIRIT II; a tendency of lower stent thrombosis in EES than in PES among those who first discontinued a thienopyridine after 6 months.

Methods And Results: A pooled analysis was performed using the 2-year clinical data from the SPIRIT II and III trials randomizing a total of 1302 patients with de novo coronary artery lesions either to EES or to PES. Inclusion and exclusion criteria were comparable between two trials.
