Trial summary

Multidetector Computed Tomographic Coronary Angiography (MDCTCA) has been recently demonstrated to be accurate and may be used as a potential alternative to conventional invasive coronary angiography, which requires cardiac catheterization, for the diagnosis of coronary artery disease.

About this study

Official title: The Ontario Multidetector Computed Tomography (MDCT) Coronary Angiography Study (OMCAS)

Multidetector Computed Tomographic Coronary Angiography (MDCTCA) has been recently demonstrated to be accurate and may be used as a potential alternative to conventional invasive coronary angiography, which requires cardiac catheterization, for the diagnosis of coronary artery disease. The purpose of this study is to see if MDCTCA can identify significant coronary artery disease as good as or better than conventional coronary angiography (CICA). The study is designed to enroll 900 subjects and is being conducted in 6 hospitals in Ontario. Subjects scheduled for conventional cardiac catheterization and coronary angiography will receive an additional test using MDCTCA. The information gathered during the MDCTCA will be compared to the results of the scheduled conventional invasive coronary angiogram.

    1 Multidetector Computed Tomography Coronary Angiography

What is being measured

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

  1. Sensitivity and specificity of MDCTCA as compared to CICA

    Measured: After both MDCTCA and CICA are completed

Secondary outcomes (3)
  1. Descriptive statistics (rates and proportions) will be calculated for the number of "avoidable" diagnostic cardiac catheterizations.

    Measured: After both MDCTCA and CICA are completed

  2. The accuracy of MDCTCA to CICA will be compared in categorizing patients inot single, double, triple vessel, left main disease or no coronary stenosis.

    Measured: After both MDCTCA and CICA are completed

  3. The accuracy of MDCTCA to eliminate correctly the need for CICA will be calculated.

    Measured: After both MDCTCA and CICA are completed

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Multidetector Computed Tomography Coronary Angiography in people with Coronary Arteriosclerosis and Cardiomyopathies, run by St. Joseph's Healthcare Hamilton at 4 sites in Canada.

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 11 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 25 Nov 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Canada. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Sensitivity and specificity of MDCTCA as compared to CICA (time frame: After both MDCTCA and CICA are completed). 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 NCT00371891, which also lists 1 linked publication.

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 25 Nov 2010.
