Brief Summary:
To determine the relative efficacy of Cardiac Computed Tomography Angiography (CCTA) and Single Positron Emission Computed Tomography (SPECT) in patients with an intermediate risk of CAD.

Condition or disease Intervention/treatment
Coronary Artery Disease Device: 64 Channel VCT

Detailed Description:

This study is a prospective, multi-center, within-subject comparative study. One hundred fifty (150) subjects with CATH procedures are needed in the study. Approximately 300 subjects who meet all of the inclusion/exclusion criteria will be enrolled. The study population will consist of subjects with symptoms suspected of and at intermediate-risk for ischemic heart disease, which are referred for MPS for a definitive diagnosis of CAD.

Each subject will undergo the following procedures:

  • A Myocardial Perfusion Study (MPS) procedure, as standard of care;
  • An IV contrast-enhanced cardiac CT (CCTA) procedure;
  • A CATH procedure when the MPS and/or cardiac CT examination is deemed positive or equivocal and at the discretion of the referring physicians, as a standard-of-care procedure.

When both the MPS and CCTA are normal, the subject is not required to undergo a CATH procedure, but will enter into follow-up. The research staff at each site will perform follow-up for each subject at 12 months (± 15 days) and 24 months (± 15 days) and 36 months (± 15 days) after the completion of the cardiac CT procedure.

Primary Outcome Measures :
  1. Detection of Significant Coronary Artery Disease Using Diagnostic Catheterization for Standard of Truth. [ Time Frame: through study completion, an expected average of 1 year ]
    Number of subjects with CT for detection purposes
