About this study

Official title: Prospective Registry of Patients With Ischemic Heart Failure Using the LifeVest Wearable Cardioverter Defibrillator (WEARIT-III)

The WEARIT-III registry enrolls subjects with ischemic cardiomyopathy and heart failure (including NYHA II, III, IV and an ejection fraction ≤ 35%) who wear a medically prescribed ZOLL LifeVest Wearable Defibrillator. The primary objective of the WEARIT-III Registry is to prospectively document the clinical course of high-risk cardiac patients with heart failure and ischemic cardiomyopathy prescribed with Wearable Cardioverter Defibrillator (WCD), such as left ventricular function recovery, arrhythmia, Implantable Cardioverter Defibrillator (ICD), Cardiac Resynchronization Therapy (CRT), Left Ventricular Assist Device (LVAD), heart transplantation, and to assess the benefit of WCD in heart failure patients with ischemic cardiomyopathy.

Read the detailed description

STUDY PROCEDURE

U.S. patients prescribed a commercially available WCD (ZOLL LifeVest) will be approached by a letter from the sponsor which summarized the study purpose and procedure. Once a patient signs a consent form to participate the study, he or she will receive three questionnaire from University of Rochester, the coordination and data center for the WEARIT registry, at the time enrollment, at 3 month and 12 month follow-up, respectively. At 3 and 12-month follow-up, the physician of the patient will be contacted to provide information on arrhythmias, and interim events (ICD, CRT or LVAD implantation, heart failure episode, death), and to send us related hospital reports and echocardiogram reports to assess the improvement in left ventricular function.

STUDY DESIGN

WEARIT-III is a prospective observational patient registry. Optimal pharmacologic and/or implanted device therapy is anticipated, and the Registry physicians will not be involved in any medical care of the subjects, only collecting information on the standard care of these patients. In WEARIT-III we will also retrieve hospital records/echocardiogram reports of the subjects during follow-up using an authorization form signed by the study subjects and contact their physician to collect information on improvement of the left ventricular function whenever it is available.

DATA MANAGEMENT, DATA STORAGE

Once consented, device recordings and prescribing information will be obtained from the device provider. Data from the subject-completed questionnaire will also be obtained. Data will be entered into our web-based, password-protected clinical data-management system. That data will then be doubled-checked for accuracy by personnel working on the Registry. All study documents will be kept in a locked file room. All computers are password-protected and kept in a locked area.

DATA ANALYSIS

Routine patient clinical data as well as WCD data and clinical outcome during 1 year of follow-up will be recorded on all study patients and entered into a study-specific data- management system using our existing data management systems in the Heart Research Follow-up Program.

All analyses will be performed based on the primary and secondary objectives. Patient's clinical characteristics will be recorded and presented by descriptive statistics. Change in the clinical course will be recorded by descriptive statistics and compared to pre- WCD and post-WCD. Time-to-event analysis will be performed to assess the time until medication optimization. Clinical event will be presented as person-time rate and will be compared to previous WCD studies. Adverse events will be evaluated by raw counts and percentages. Compliance will be analyzed by mean and median of length of use and daily wear time.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LifeVestDevice

    Also called Wearable Cardioverter Defibrillator WCD

    LifeVest monitors patients for VT/VF, notifies the patient if VT/VF occurs, and instructs them to press response buttons. In unresponsive patients, LifeVest delivers defibrillation therapy.

What is being measured

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

  1. Number of clinical events in heart failure patients with ischemic cardiomyopathy prescribed wearable cardioverter defibrillator (WCD)

    The primary objective of the WEARIT-III Registry is to prospectively document the clinical course of high-risk cardiac patients with heart failure and ischemic cardiomyopathy prescribed with WCD, such as left ventricular function recovery, arrhythmia, implantable cardioverter defibrillator (ICD), cardiac resynchronization therapy (CRT), left ventricular assist device (LVAD), heart transplantation, and to assess the benefit of WCD in heart failure patients with ischemic cardiomyopathy.

    Measured: 1 year

Secondary outcomes (4)
  1. All-cause mortality

    Evaluate the number of deaths and the cause of death in patients with ischemic cardiomyopathy and heart failure prescribed with WCD.

    Measured: 1 year

  2. Number of inappropriate shocks

    Evaluate the safety of WCD in patients with ischemic cardiomyopathy and heart failure measured by the frequency of inappropriate WCD shocks

    Measured: 1 year

  3. WCD shock conversion success rate

    Evaluate WCD shock efficacy measured by shock conversion success rate among WCD appropriate shocks

    Measured: 1 year

  4. NYHA functional class

    Evaluate the NYHA functional class of heart failure patients with ischemic cardiomyopathy at enrollment, 3-month and 1-year after the initial prescription of the WCD in WEARIT-III

    Measured: At enrollment, 3-month and 1-year follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Ischemic Heart Failure, run by Zoll Medical Corporation at 1 site in United States.

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 6 inclusion and 6 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 28 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 clinical events in heart failure patients with ischemic cardiomyopathy prescribed wearable cardioverter defibrillator (WCD) (time frame: 1 year). 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 28 Mar 2019.
