3. The Surgical Treatment of Ischemic Heart Failure (STICH) Research Program: Background of SVR Trial • Subset of ischemic cardiomyopathy pts develop progressive HF due to adverse LV remodeling • Surgical ventricular reconstruction (SVR) is novel procedure to  LV size, create more normal LV shape • Observational studies of SVR have shown improvement in HF symptoms and QOL • Since SVR almost always done with CABG, unclear what specific incremental benefits the procedure provides. Also, economics of procedure unknown.

4. STICH 1° Hypothesis and Design Overview 1° Hypothesis: Adding SVR to CABG in ischemic HF pts will  death/ cardiac rehospitalization 1000 HF pts (2002-2006) CAD, EF ≤ .35, anterior LV wall scar amenable to SVR 499 CABG only 501 CABG + SVR Median follow-up 48 months • 7% did not receive operation • 9% did not receive operation

7. STICH Economics and Quality of Life Study:Key Questions • Does SVR added to CABG significantly improve functioning and well-being in ischemic heart failure? • What are the economic implications of adding SVR to CABG in patients with ischemic heart failure?

8. EQOL STICH:Quality of Life (QOL) Methods Overview • QOL structured interviews at baseline and 4, 12, 24, and 36 months post-randomization • 991 (99%) of 1000 main STICH pts in QOL • 4136 (92%) expected QOL contacts collected

16. STICH Economic Substudy: Methods Overview • Resource use data from CRF and medical bills • Bills collected on 196 of 200 (98%) U.S. patients • Costs estimated using hospital bills, Medicare correction factors, and Medicare fee schedule • Outpatient care, medications, productivity costs, non-medical costs not included • Cost effectiveness not performed (SVR arm not clinically superior to CABG alone) • Results reported in 2008 US$

20. EQOL STICH:Limitations • Unblinded treatment assignment, participation in RCT may distort care • Resource use and cost patterns seen in the U.S. cohort do not reflect patterns in other participating countries

21. STICH Economic and Quality of Life Outcomes:Summary • STICH is first RCT comparing 2 cardiac surgical treatment strategies • Adding SVR to CABG does not provide any incremental improvements in QOL out to 3 years post-surgery • SVR ↑ complexity of post-operative care and significantly ↑ costs of the procedure over CABG alone • No benefit for continued routine use of this procedure in STICH-eligible pts
