Trial summary
This study is being done to determine if a picture taking test of the heart, positron emission tomography/computed tomography (or cardiac PET/CT), can identify the blockages in the heart arteries that lead to heart attacks when compared to the standard of heart catheterization.

About this study
Official title: Comparison of Cardiac Positron Emission Tomography/Computed Tomography (PET/CT) With Coronary Angiography (CA) and Intravascular Ultrasound (IVUS) in the Diagnosis and Characterization of Coronary Artery Plaque
This study is being done to determine if a picture taking test of the heart, positron emission tomography/computed tomography (or cardiac PET/CT), can identify the blockages in the heart arteries that lead to heart attacks when compared to the standard of heart catheterization.
Read the detailed description
Heart catheterization, in which a thin plastic tube, or catheter, is placed into an artery in the arm or leg and advanced into the heart arteries, is the procedure that you and your doctor have decided to pursue to look for heart artery blockages. It is being performed as part of your standard care and not for research purposes. The research procedure (cardiac PET/CT), which will be performed at a later date is a combination of heart CT (a test that involves the use of x-rays to identify heart artery blockages) and heart PET (an imaging test that uses a radioactive drug to look at how the heart uses fuel (sugar and fats) These tests will be combined (PET/CT) to look for the presence and type of blockage in your heart arteries.
It is important to develop a test that can determine if and what type of blockage you have in your heart arteries as the presence and type of heart artery blockage is a very important predictor of heart attack and death from heart attack.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PET/CTDiagnostic test
Also called PET/positron Emission Tomography imaging
Patient will have one imaging modality - a Positron Emitting Tomography CT which includes F-18 FDG and heparin/intralipid infusion and Contrast Dye.
| Study group | Role | What they receive |
|---|---|---|
| Positron Emitting Image | Experimental | Patient will have a PET/CT imaging study to determine cardiac stenosis, F-18 FDG and heparin/intralipid infusion and Contrast Dye.will be administered. Receives: Diagnostic Test: PET/CT |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Clear Anatomical Landmarks Confirmed by CT
Coronary FDG uptake will be measured at the site of coronary stenosis. The target coronary stenosis will be identified by its proximity to a clear anatomical landmark seen on CT and conventional angiography.
Measured: During PET CT scan, an average of 2 hours

Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 29 Aug 2018. 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 29 Aug 2018). 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?
Number of Participants With Clear Anatomical Landmarks Confirmed by CT (time frame: During PET CT scan, an average of 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 29 Aug 2018; AzTrials last refreshed its copy on 7 Nov 2026.
