This protocol details a novel myocardial perfusion Single Photon Emission Computed Tomography (SPECT) protocol wherein patients receive a low-dose (6 mCi) of Tc-99m sestamibi during exercise or regadenoson pharmacologic stress and undergo a full-time SPECT acquisition processed with Wide Beam Reconstruction (WBR). Immediately thereafter patients receive a high-dose (30-35 mCi) of Tc-99m sestamibi at rest and undergo a half-time rest scan, also processed with WBR. All enrolled research subjects will undergo both the initial stress and subsequent rest scan.

The radiation exposure associated with this new stress/rest protocol is equivalent to that of the conventional rest/stress protocol presently in routine clinical uses at SLRHC.

Eventually, when and if this novel stress/rest protocol is adopted in routine clinical practice, patients with normal stress scans would receive only 6 mCi of Tc-99m sestamibi (331 mSv in men, 241 mSv in women) and spend only approximately one hour in the Nuclear Medicine Laboratory.

All patients presenting to the Nuclear Medicine Laboratory for evaluation of known or suspected coronary artery disease will be candidates for enrollment. Fifty patients undergoing treadmill exercise stress and 50 patients undergoing regadenoson pharmacologic stress will be enrolled. Pregnant and breast-feeding patients will not be eligible.

Primary Outcome Measures:
  • Myocardial perfusion SPECT image quality [ Time Frame: immediately following SPECT image processing (1 hour after the test) ] [ Designated as safety issue: No ]

    Myocardial perfusion SPECT iamge quality is determined by visual inspection of the processed images. Criteria used include uniformity of the myocardium, definition of the endocardial and epicardial borders, definition of the valve plane, background activity, and visualization of the right ventricle.

    Please not that patient outcomes are NOT measured in this research protocol.

Secondary Outcome Measures:
  • rest/stress myocardial count density ratio [ Time Frame: immediately following SPECT image processing (1 hour after the test) ] [ Designated as safety issue: No ]

    The rest and stress myocardial count densities are determined automatically using Evolution software on the GE Healthcare Xeleris Nuclear Medicine computer workstation. The ratio is calculated by simple division.

    Please not that patient outcomes are NOT measured in this research protocol.
