The purpose of this study is to determine whether coronary artery CT scanning or nuclear stress testing is better at diagnosing chest pain patients with coronary artery disease to select appropriate candidates for coronary catheterization and re-vascularization.

Condition Intervention
Coronary Artery Disease
Angina Pectoris
Unstable Angina
Acute Coronary Syndrome
Procedure: Coronary Computed Tomography Angiography
Procedure: Stress Nuclear Myocardial Perfusion Imaging

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: A Randomized Trial Comparing Multi-Detector Coronary CT Angiography and Stress Myocardial Perfusion Imaging as the Initial Test for the Diagnosis of Coronary Artery Disease in Intermediate Risk Patients Admitted for Chest Pain

Further study details as provided by Montefiore Medical Center:

Primary Outcome Measures:
  • Coronary catheterization that does not lead to re-vascularization [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Length of Hospital Stay (time to discharge) [ Time Frame: usually from hours to a few days (average about one day) ]
  • Non-fatal myocardial infarction [ Time Frame: 1 year ]
  • Death (all cause) [ Time Frame: 1 year ]
  • Post-test renal dysfunction [ Time Frame: usually within a few days ]

Enrollment: 400
Study Start Date: July 2008
Study Completion Date: December 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CTA
Initial EKG-gated computed tomography angiography of the coronary arteries
Procedure: Coronary Computed Tomography Angiography
64-detector, retrospectively EKG-gated, computed tomography angiography of the coronary arteries during heart rate control (intravenous metoprolol, when necessary)
Other Names:
  • CCTA
  • Coronary CT
  • Coronary CTA
  • Coronary Artery CT
  • Coronary Artery CTA
  • Coronary CT Angiography
  • CTA of the Coronary Arteries
Active Comparator: MPI
Initial nuclear stress myocardial perfusion imaging
Procedure: Stress Nuclear Myocardial Perfusion Imaging
Usually dual-isotope perfusion imaging at rest (201-Thallium) and at stress (99m-Technetium-MIBI). Some patients will have a 2-day MIBI protocol. Gated SPECT and attenuation-correction images will be obtained. Treadmill stress will be performed. If a patient is unable to exercise, adenosine or dobutamine will be given.
Other Names:
  • stress test
  • nuclear stress test
  • dual-isotope stress test
  • sestamibi
  • thallium
  • myocardial perfusion imaging
  • nuclear perfusion imaging
  • gated SPECT
  • nuclear cardiology
