16Conclusions
- SPIRIT II 2 year data shows a consistent
reduction in clinical events for XIENCE V vs
TAXUS (MACE 6.6 vs 11.0) - Low stent thrombosis rate for XIENCE V at 2
years (0.9 XIENCE V vs 1.4 TAXUS ) - XIENCE V remains numerically lower than TAXUS
in MACE and all it's components at 2 year
follow-up, despite a modest increase in late loss
and neo-intima in the XIENCE V arm over time.
