About this study

Official title: Non-invasive Evaluation of Coronary Pathology by Transthoracic Doppler Echocardiography. A Comparative Study to Coronary Angiography.

Non-invasive evaluation of patients with stable angina and unstable coronary syndromes with transthoracic Doppler echocardiography to evaluate presence of significant coronary stenoses. Blinded evaluation and comparison with coronary angiography: presence and location of stenoses, and head to head comparison of clinical value and patient classification.

Read the detailed description

Transthoracic Doppler echocardiographic evaluation with extensive evaluation of coronary stenoses in all 3 main branches using colour flow, pulsed Doppler and Coronary flow velocity reserve (CFVR)after pharmacologic stress with adenosin in the area of LAD and RDP. Blinded evaluation of Doppler results and coronary angiography regarding the other examination modality. Coronary angiography diagnostic "gold standard". Only stable and unstable patients otherwise scheduled for angiography on clinical reasons will be examined and included in the study.

Added January 2007 after ethics committee approval: comparison of CFVR with invasive fractional flow reserve (FFR) in selected subset of patients.

Questions about this trial

What is this clinical trial studying?

A study testing Doppler echocardiography in people with Stable Angina Pectoris and Unstable Angina Pectoris, run by Norwegian University of Science and Technology at 1 site in Norway.

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 2 inclusion and 1 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 18 Jul 2016. 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 Norway. 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?

Diagnostic yield: Accuracy, positive and negative predictive value. (time frame: Inhospital). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00281346, which also lists 4 linked publications.

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 18 Jul 2016.
