3. www. Clinical trial results.org PEECH Trial: Primary Endpoint The primary endpoint of increase in exercise duration by at least 60 seconds occurred more frequently in the EECP group compared with the control group at a 6 month follow-up. The co-primary endpoint of increase in peak VO2 of at least 1.25 ml/min/kg was the same between the two groups. Primary endpoints of increase in excercise duration at 6 months & increase in peak VO2 Presented at ACC 2005 p=0.016 p=NS 22.8% 35.4% 25.3% 24.1%

4. www. Clinical trial results.org PEECH Trial: Secondary Endpoint of Change in Exercise Duration Presented at ACC 2005 p=0.01 The change in exercise duration was longer in the EECP group versus the control group, which actually had a decrease in exercise duration at 1 week and 6 months. The change in exercise duration was longer in the EECP group versus the control group, which actually had a decrease in exercise duration at 1 week and 6 months. The increase in the EECP group’s exercise duration was maintained at the 6 month follow- up. The increase in the EECP group’s exercise duration was maintained at the 6 month follow- up.

5. www. Clinical trial results.org PEECH Trial: Secondary Endpoint There was more improvement in NYHA classification in the EECP group compared to the control group. The was no significant difference in the occurrence of serious adverse events between groups. Presented at ACC 2005 p<0.001 p=NS % Change in NYHA Class

6. www. Clinical trial results.org PEECH Trial: Secondary Endpoint Presented at ACC 2005 There was a greater change from baseline in Minnesota Living with Heart Failure scores in the EECP group at 1 week and 3 months compared to the control group; however, there was no difference between the groups at the 6 month follow-up. p=0.01 p=NS MN Living with CHF Score

7. www. Clinical trial results.org PEECH Trial: Summary Among patients with systolic dysfunction, stable heart failure symptoms and treated with optimal pharmacologic therapy, the use of EECP was associated with improvements in exercise duration, NYHA classification and quality of life but no difference in change in peak VO2 compared with optimal pharmacologic therapy alone In the past, EECP therapy has been demonstrated benefit in increasing time to exercise induced ischemia and has been associated with decreased anginal frequency among patients with stable angina Data in patients with heart failure are limited to a registry and a pilot trial The present study demonstrated improvements in exercise duration and quality of life despite optimal medical therapy Among patients with systolic dysfunction, stable heart failure symptoms and treated with optimal pharmacologic therapy, the use of EECP was associated with improvements in exercise duration, NYHA classification and quality of life but no difference in change in peak VO2 compared with optimal pharmacologic therapy alone In the past, EECP therapy has been demonstrated benefit in increasing time to exercise induced ischemia and has been associated with decreased anginal frequency among patients with stable angina Data in patients with heart failure are limited to a registry and a pilot trial The present study demonstrated improvements in exercise duration and quality of life despite optimal medical therapy Presented at ACC 2005
