Trial summary

It is an observational study in patients with heart failure investigating the incidence of arrhythmias using a wearable device which can monitor heart rhythm for up to 14 days. In addition to gathering routine clinical information, research assessments include a symptoms questionnaire and a corridor walk test. Read more about this study

About this study

Official title: A Prospective Observational Study of Prolonged Electrocardiographic Monitoring in Patients With Heart Failure in Sinus Rhythm or Atrial Fibrillation

It is an observational study in patients with heart failure investigating the incidence of arrhythmias using a wearable device which can monitor heart rhythm for up to 14 days. In addition to gathering routine clinical information, research assessments include a symptoms questionnaire and a corridor walk test. Patients will be followed for clinical events (interventions for arrhythmias, hospitalisation, death) for 1 year.

Read the detailed description

due to the slow recruitment, on the one hand, and the fact that the preliminary analysis gave the valuable results, on the other hand, the number of patients was reduced from 400 to 100 and the follow-up from five years to one year

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With an Identified Dysrhythmia on Baseline ECG Recording

    A dysrhythmia will be defined as either

    1. Arrhythmia for which there is a Class I or IIa recommendation for treatment with medication or devices in ESC guidelines.
    2. One or more of the following even if it does not otherwise meet guideline-indication for treatment:
    • Sinus bradycardia ≤30bpm for ≥one minute
    • High-degree atrioventricular (AV) block (3rd degree or Mobitz Type I or II)
    • Pauses lasting ≥3 seconds (either sinus or AV block)
    • Frequent ventricular ectopy defined as >1,000 ectopic beats per day.
    • Ventricular tachycardia with rate ≥100 bpm for ≥5 beats.

    Measured: on enrollment

Secondary outcomes (6)
  1. Combined Endpoint Made up of Cardiovascular Mortality or Hospitalisation for the Management of Heart Failure/Arrhythmia or Implantation of Any Permanent Device Capable of Pacing the Heart.

    information about new implantations and hospitalisations were known for 46 patients with sinus rhythm (97.9%) and 47 with atrial fibrillation (94%)

    Measured: From date of enrollment until the date of first hospitalization for management of heart failure/arrhythmia or date of implantation of any permanent device capable of pacing the heart or cardiovascular death, whichever came first, assessed up to 1 years

  2. All Cause Mortality

    survival status was known in 46 patients with sinus rhythm (97.9%) and 50 patients with atrial fibrillation (100%)

    Measured: 1 year

  3. Cardiovascular Mortality

    Measured: 1 year

  4. Total Number of Hospitalisations for the Management of Heart Failure or Arrhythmia

    Measured: 1 year

  5. Total Number of Patients Implanted With Any Permanent Device Capable of Pacing the Heart

    information about new implantations were known for 46 patients with sinus rhythm (97.9%) and 47 with atrial fibrillation (94%)

    Measured: 1 year

  6. Implantation of Any Permanent Device Capable of Pacing the Heart

    information about new implantations were known for 46 patients with sinus rhythm (97.9%) and 47 with atrial fibrillation (94%)

    Measured: From date of enrollment until the date of implantation of any permanent device capable of pacing the heart, assessed up to 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure and Atrial Fibrillation, run by Imperial College London at 3 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With an Identified Dysrhythmia on Baseline ECG Recording (time frame: on enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2023.
