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 Radiation: Positron Emission Tomography Radiation: 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose Radiation: Computed Tomography Drug: CT Contrast Dye 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.

Arm Intervention/treatment
Experimental: PET/CT
If enrolled in this study, the participant will have a PET/CT along with their Cardiac Catheterization to compare usability of images in diagnosis of heart vessel disease.
Radiation: Positron Emission Tomography
image scan. approximately 1 hour
Other Name: PET

Radiation: 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose
maximum of 10mCi of 18F-FDG will be injected for imaging purposes
Other Name: 18F- FDG

Radiation: Computed Tomography
image scan
Other Name: CT.

Drug: CT Contrast Dye
used for obtaining images. weight based dose
Other Name: CT contrast

Primary Outcome Measures :
  1. To determine if a combined non-invasive cardiac imaging test (PET/CT) can determine coronary plaque severity, morphology and metabolic activity when compared to the gold standard of coronary angiography and intravascular ultrasound. [ Time Frame: 1.5 years ]
