SPIRIT II Explores Long-Term Performance of XIEN...(nical outcomescompared to the Taxus sten...),Health

Date:3/31/2008

nical outcomes compared to the Taxus stent at two years, however, the trial was not statistically powered to show differences in clinical endpoints. The overall MACE rate at two years was 40 percent lower in patients treated with the XIENCE V stent (6.6 percent vs. 11.0 percent in the Taxus group). Repeat procedures to treat the target lesion were performed in 3.8 percent and 6.8 percent of patients, respectively, a 44 percent reduction favoring the XIENCE V stent. Similarly, the rates of heart attack were 2.8 percent and 5.5 percent, respectively, a 49 percent reduction, and the rates of cardiac death were 0.5 percent and 1.4 percent, respectively, a 64 percent reduction. There was no difference in the rates of blood clotting inside the stent, or stent thrombosis, at two years.

In the 117 patients who had follow-up angiography at two years, there was no significant difference in the rates of re-narrowing of at least 50 percent (binary restenosis) within the stents (2.1 percent with the XIENCE V stent vs. 2.9 percent with the Taxus stent). In-stent late loss was virtually identical (0.33 mm vs. 0.34 mm, on average, respectively).

Dr. Serruys will present the two-year results of the SPIRIT II study on Monday, March 31 at 8:45 a.m. CDT in the Grand Ballroom, S100.
