  Purpose

The purpose of this clinical research study is to evaluate the safety of an investigational implantable hemodynamic monitor (IHM). The IHM is implanted surgically under the skin in the upper chest area and records the force with which the heart pumps blood (heart pressures). This study will also determine how doctors use the information related to heart pressures in the management of heart failure.

Primary Outcome Measures:
  • To evaluate the safety of the implantable hemodynamic monitor by demonstrating freedom from system-related complications greater than or equal to 80% at 6 months. [ Time Frame: Within 6 months post-implant ] [ Designated as safety issue: Yes ]
  • To evaluate the safety of the implantable hemodynamic monitor by demonstrating freedom from pressure related sensor lead failure greater than or equal to 90% at 6 months. [ Time Frame: Within 6 months post-implant ] [ Designated as safety issue: Yes ]
  • To assess the efficacy of designated treatment strategies by demonstrating a reduction in the rate of all heart failure events in the treatment group compared to the control group. [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Health Care Utilization [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • Subject survival and days alive out of the hospital [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • Rate of adverse events [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • Retrospective analysis of the predictive value of pressure change in the control group [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • Clinical composite response of either "worsened", "improved", or "unchanged" [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • Quality of Life measured by the Minnesota Living with Heart Failure questionnaire [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • New York Heart Association (NYHA) Class [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]
  • Distance walked during a six minute hall walk [ Time Frame: 6 Months post-implant ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

  • Subjects with heart failure classified as New York Heart Association (NYHA) Class III and IV
  • Subject has been managed with standard medical therapy for heart failure (such as diuretic, angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blockers (ARB), and beta-blocker for at least 3 months prior to the baseline evaluation
  • Subject must have at least one heart failure-related hospitalization or emergency department visit requiring intravenous treatment within 6 months prior to baseline evaluation

Exclusion Criteria:

  • Subjects who are likely to be transplanted within 6 months from randomization or will remain hospitalized until transplantation
  • Subjects with severe COPD or restrictive airway disease (recommended FEV1 less than or equal to 1 liter or 50% predicted)
  • Subjects who are on continuous positive inotropic therapy
  • Subjects with known atrial or ventricular septal defects
  • Subjects with mechanical right heart valves
  • Subjects with stenotic tricuspid or pulmonary valves
  • Subjects with a presently implanted non-compatible pacemaker or ICD
  • Subjects with cardiac resynchronization therapy which has not achieved optimal programming for more than 3 months
  • Subjects with a major cardiovascular event within 3 months prior to baseline evaluation
  • Subjects with a severe non-cardiac condition limiting 6 month survival
  • Subjects with a primary diagnosis of pulmonary artery hypertension
  • Subjects with serum creatinine greater than or equal to 3.5 mg/dL or on chronic renal dialysis
  • Subjects enrolled in concurrent studies that may confound the results of this study
  • Women who are pregnant or with child bearing potential and who are not on a reliable form of birth control
