About this study

The study is an open prospective study of coronary flow preferably of the left anterior descending artery (LAD), by a Transthoracic Parametric Doppler (TPD) system during conventional exercise stress test. The system is a noninvasive non-imaging device designed to monitor coronary flow velocity and display the data continuously during exercise stress tests. The system enables continuous monitoring of coronary flow during resting, stress loading and recovery phases. The study intent is to improve the stress test predictive value for CAD.

Questions about this trial

What is this clinical trial studying?

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 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: stopped early, as of the sponsor's last update on 5 Aug 2014. 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 Israel. 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 was stopped early. Results are not available in the source record.

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?

Monitor coronary artery flow during exercise stress test. (time frame: 1-3 months following the stress test). 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 5 Aug 2014.
