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.

Condition or disease Intervention/treatment Phase
Myocardial Infarction Coronary Artery Disease Cardiac Catheterization Diagnostic Test: PET/CT Not Applicable

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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 3 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
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
Study Start Date : October 2007
Actual Primary Completion Date : September 2009
Actual Study Completion Date : September 2009

Arm Intervention/treatment
Experimental: Positron Emitting Image
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.
Diagnostic Test: PET/CT
Patient will have one imaging modality - a Positron Emitting Tomography CT which includes F-18 FDG and heparin/intralipid infusion and Contrast Dye.
Other Name: PET/positron Emission Tomography imaging

Primary Outcome Measures :
  1. Number of Participants With Clear Anatomical Landmarks Confirmed by CT [ Time Frame: During 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.
