Heart failure & cardiomyopathiesCohort study
Physician-Directed Patient Self-Management Using an Implantable Inferior Vena Cava (IVC) Congestion Sensor
- Prospective cohort study
- 2 sequential prospective cohorts
- early feasibility study
Authors' conclusion
Physician-directed patient self-management using ambulatory IVC-based congestion monitoring was feasible, associated with increased signal-driven intervention, and not associated with adverse safety signals. This strategy demonstrated favorable clinical signals.
Study context
- Population
- Heart failure (HF) patients with an implantable IVC-based congestion management system (FUTURE-HFII)
- Participants
- 10 vs 15
- Exposure
- Self-management vs Clinician-managed care
- Self-managementn = 10
- Clinician-managed caren = 15reference
- Outcome
- Safety, device adherence, medication adjustments, congestion metrics, HF events and quality of life
- Follow-up
- 90 days
Main finding
As reported in the abstract
- No safety signals were observed
Observational data: associations, not effects.
Further findings
| Outcome | RR | P value |
|---|---|---|
| Diuretic changes per patient (signal intervention frequency) · 10.4 vs 2.8 diuretic changes per patient | 3.71 | P < 0.01 |
Daily device usage
- High in both groups, numerically greater with self-management
- 90.5% vs 84.8%
- 1,927 measurements
Congestion control (NORM score time-in-range)
- Comparable between groups
Quality of life (KCCQ-CSS gain ≥5 points)
- Improved in both groups, larger gains in the self-managed cohort
- 60.0% vs 46.7%
