PET/CT Study in the Diagnosis of Coronary Plaque

Not Applicable
Terminated
Conditions
Myocardial Infarction
Cardiac Catheterization
Coronary Artery Disease
Interventions
Diagnostic Test: PET/CT
Registration Number
NCT00850473
Lead Sponsor
Washington University School of Medicine
Brief 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.

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.

Positron Emitting ImagePET/CTPatient will have a PET/CT imaging study to determine cardiac stenosis, F-18 FDG and heparin/intralipid infusion and Contrast Dye.will be administered.
Primary Outcome Measures
NameTimeMethod
Number of Participants With Clear Anatomical Landmarks Confirmed by CTDuring PET CT scan, an average of 2 hours

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.
