12 PURPOSE and METHODS The SPIRIT Women Study provides an evaluation of the safety and efficacy of the XIENCE V® Everolimus Eluting Coronary Stent (EES) in the female population undergoing stent implantation*. SPIRIT Women is a prospective, open-label, single arm, all-comer multi-center study conducted at 73 sites outside of the United States female patients were enrolled between July 2007 and March 2009. Maximum of 4 planned XIENCE V EESCC, Target lesions must be de novo Reference diameter between 2.5 mm and 4.0 mm Lesion length ≤ 28 mm. SPIRIT Women is the first major interventional trial with drug eluting stents to focus on women and specific aspects of their health in relation to CAD

The mean lesion length was 15mm and 29% of lesions were >=20mm. Eccentric 44% Moderate or Severe Calcium 30% Lesion Angulation >45º 23% >1 Target Lesion 32% Target Lesions Treated/Patient 1.4 ACC Lesion B2 or C 72% *Visually assessed by Investigator

18 PRIMARY ENDPOINT RESULTS*
1 YEAR ARC DEFINED PRIMARY ENDPOINT RESULTS* All Death, MI and TVR % 6 9 12 15 3 XIENCE V 37 393 Days Post Index Procedure 7,8% 12% The 12% composite endpoint rate was mainly driven by the high MI rate of 9%. Out of 139 MI events, 110 were peri-procedural MI events. *Previous MI rates in SPIRIT III and SPIRIT IV were adjudicated using historical WHO definition. Events in SPIRIT Women were adjudicated according to Academic Research Consortium (ARC) Definitions (Peri-procedural MI=Troponin >3 times ULN)

19 1 YEAR ARC DEFINED CLINICAL RESULTS Non-Hierarchical N=1550
All Death (%) Cardiac Death 1.6 0.8 All ARC Defined MI* (%) ARC Defined Peri-procedural MI ARC Defined TV MI** 9.2 7.1# 8.7 ARC Defined Q-Wave TV MI 0.1 ARC Defined Non Q-Wave TV MI 8.6 TLR (%) 2.4 by PCI 2.1 by CABG 0.3 TVR including TLR (%) 3.0 2.7 Low rates of TLR and TVR for this complex patient and lesion population. #111 out of 1572 patients (7.1%) had an ARC Defined Peri-procedural MI All revascularizations are considered clinically indicated

20 1 YEAR ARC DEFINED STENT THROMBOSIS
*90% of patients on Clopidogrel and 96% on Aspirin at 1 year follow-up No subacute definite stent thromboses occurred

21 CONCLUSIONS Results of the SPIRIT IV trial at 2 years demonstrated that women treated with XIENCE V EES had sustained superior safety and effectiveness with an 83% RRR in stent thrombosis compared to the Taxus stent SPIRIT Women is the first prospective post-market study in an exclusively female “all comers” population evaluating high risk women XIENCE V® has proven safe and effective with low rates of Target Lesion Revascularization (2.4%) and Stent Thrombosis (0.59%) despite the complexity of the population
