Trial summary

The purpose of this study is to compare different methods of looking at atherosclerotic plaques in heart arteries. Identifying the characteristics of these plaques noninvasively would be very valuable. Read more about this study

About this study

Official title: Comparison of Dual Source Computed Tomography (DSCT) With Integrated Backscatter Intravascular Ultrasound (IB-IVUS) and Contrast Angiography in the Assessment of Coronary Artery Disease

The purpose of this study is to compare different methods of looking at atherosclerotic plaques in heart arteries. Identifying the characteristics of these plaques noninvasively would be very valuable. This study is looking at a new CT scanner (DSCT) to noninvasively image these plaques compared to invasive ultrasound (the current standard).

Read the detailed description

The primary objectives of this study are:

  1. To compare with contrast angiography, the ability of DSCT to detect and quantify coronary artery stenoses.
  2. To compare with gray-scale IVUS, the ability of DSCT to quantify plaque cross-sectional diameter \& area measurements \& plaque volume.
  3. To evaluate the ability of DSCT to assess plaque morphology and quantify plaque components as compared to gray-scale and IB-IVUS.
  4. To evaluate the ability of DSCT to identify \& measure lesion remodeling compared to gray-scale IVUS.
  5. To determine if pre-PCI evaluation of coronary plaque morphology by IB-IVUS can a) predict procedural success as assessed by adequate stent strut apposition and expansion and b) peri-procedural myocardial necrosis as measured by biomarker elevation.

Questions about this trial

What is this clinical trial studying?

A study testing Integrated Backscatter IVUS and Dual Source Computed Tomography in people with Coronary Artery Disease, run by Massachusetts General Hospital 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 3 inclusion and 16 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: stopped early, as of the sponsor's last update on 3 Feb 2012. 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?

Yes. Results are posted in the registry (first posted 3 Feb 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Comparison of Plaque Characteristics Between DSCT (Dual Source Computed Tomography) and IVUS (Intravascular Ultrasound). (time frame: At time of imaging). 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 3 Feb 2012.
