Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1 Primary Efficacy Objectives To describe the effects of the Rheos Baroreflex Activation Therapy System on the left ventricular mass index (LVMI) at six months post-randomization. 2. Primary Measures of Safety To assess the safety of Rheos Baroreflex Activation Therapy System by evaluating all adverse events and estimating the serious system and procedure related adverse event rate through six months post-implant. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To assess the difference between randomization groups in blood pressure changes from pre-implant between the Rheos ON and Rheos OFF arms at 3 and 6 months post-randomization. 2. To assess the difference between randomization groups in the increase in the six-minute hall walk distance at 3 and 6 months post-randomization. 3. To assess the difference between randomization groups in changes in E/e* from pre-implant between the Rheos ON and Rheos OFF arms at 3 and 6 months post-randomization. 4. To assess the difference between randomization groups in the improvement in the Minnesota Living with Heart Failure Questionnaire index score at 3 and 6 months post-randomization. 5. To assess the differences between randomization groups in the reduction in NT-pro-BNP at 3 and 6 months post-randomization. | — |
