Why the study?

Heart failure poses a global challenge with traditional management contributing to high readmission and mortality rates, prompting evaluation of autonomous peripheral oedema monitoring.

Does the Heartfelt device improve the prediction of heart failure decompensation compared to traditional weighing in patients with heart failure?

Population

31 patients enrolled across five UK NHS trusts

Comparison

Heartfelt remote peripheral oedema monitoring vs traditional weighing (standard care)

Design

Multicentre observational study

Key result

The Heartfelt remote monitoring device predicted heart failure decompensation with a 13-day lead time, providing more consistent and frequent data than traditional weighing methods.

Overview

May facilitate earlier HF intervention than daily weights; extends remote monitoring evidence but leaves open impact on outcomes.

Key Points

  • The study evaluates the Heartfelt device's effectiveness in predicting heart failure events through remote monitoring.
  • Conducted as an observational study across five UK NHS trusts.
  • Enrolled 31 patients, with 26 actively monitored for heart failure events.
  • Assessed predictive accuracy and data collection frequency of the Heartfelt device versus traditional methods.
  • Heartfelt device predicted heart failure decompensation with a lead time of 13 days.
  • Provided more consistent and frequent data collection compared to traditional weighing.
  • Six heart failure events were observed among monitored patients.

Structured PICO

Does the Heartfelt device improve the prediction of heart failure decompensation compared to traditional weighing in patients with heart failure?

P
Population
Patients with heart failure
I
Intervention
Heartfelt device for remote, autonomous monitoring of peripheral oedema
C
Comparator
Traditional weighing (standard care)
O
Outcome
Predictive accuracy, data collection frequency, consistency versus traditional weighing, lead time for intervention and event prediction sensitivity

The Heartfelt device provides continuous remote monitoring of peripheral edema, potentially allowing for earlier detection of heart failure decompensation with a 13-day lead time compared to standard care.
