What participants receive

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

  • Stress Dobutamine Echocardiographic using 4DE SystemProcedure or surgery

    Subjects will undergo their clinically indicated stress dobutamine echocardiographic studies using our standard clinical graded dobutamine stress imaging protcol, employing the iE33 4DE system.

What is being measured

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

  1. Number of Subjects With an Interpretable 4DE Image

    This outcome will measure feasibility. Data from images will be analyzed with the integrated speckle/shape tracking approach (the method uses boundary detection/shape tracking to quantify left ventricular myocardial deformation)

    Measured: After Stress Echocardiography (Approximately 2 hours)

Questions about this trial

What is this clinical trial studying?

A study testing Stress Dobutamine Echocardiographic using 4DE System in people with Coronary Artery Disease, run by Yale University.

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 3 inclusion and 7 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The record says: withdrawn, as of the sponsor's last update on 13 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

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The study was withdrawn before enrolling participants, so there are no results.

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 Subjects With an Interpretable 4DE Image (time frame: After Stress Echocardiography (Approximately 2 hours)). 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 13 Dec 2023.
