About this study

Official title: Optimization of Cardiac Resynchronization Therapy Using an ECG Vest

Despite advancements in implant technology and various techniques of optimization, there is still around 30% non-responder rate to cardiac resynchronization therapy (CRT). This study will assess the potential benefit of a body surface mapping technology to optimize CRT devices in the chronic sub-optimal responder setting.

Read the detailed description

Cardiac resynchronization therapy (CRT) is one of the most important advances in the treatment of patients with heart failure (HF). This therapy, also known as biventricular pacing, utilizes pacemaker leads to synchronize the contraction of the walls within the left ventricle (LV) and the contraction of the left and right ventricles. Many randomized trials have conclusively demonstrated that CRT improves symptoms, LV structure and function, hospitalization rates, and survival in appropriately selected HF patients. Nonetheless, approximately 30% of CRT patients will be "non-responders" because they will not demonstrate the expected clinical and/or echocardiographic improvement following therapy. A critical component of assessing CRT efficacy during the optimization clinic will be the use of a novel method of body surface electrocardiographic mapping under development by Medtronic, called the ECG Vest. In this proposal, we describe a research study to assess the potential benefit of using the ECG Vest as part of a CRT optimization strategy on clinical and echocardiographic outcomes (heart size and function) of patients receiving standard clinical care in the UHVC CRT Optimization Clinic.

What participants receive

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

  • ECG Vest OptimizationDevice

    As part of a standard and clinically indicated CRT optimization procedure utilize an ECG Vest as one modality for collecting information to determine best device programming.

Study groups in NCT02699944
Study groupRoleWhat they receive
CRT sub-optimal responderExperimentalSubjects who have had CRT for at least 6 months and who have not responded as well as they could, in their cardiologists opinion. Subjects' ejection fraction are still <50% despite CRT. A ECG Vest Optimization protocol will be utilized as one aspect to determine the best CRT programming for each individual subject.

What is being measured

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

  1. Change in left ventricular end-systolic volume

    Measured: 6 months after optimization

Secondary outcomes (1)
  1. Determine the degree to which echocardiographic measures of LV function correlate with ECG Vest measures

    Measured: 6 months after optimization

Questions about this trial

What is this clinical trial studying?

A study testing ECG Vest Optimization in people with Heart Failure, run by Alan J. Bank, MD 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 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 23 Sep 2021. 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?

Change in left ventricular end-systolic volume (time frame: 6 months after optimization). 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 23 Sep 2021.
