|Coronary Artery Disease|
|Study Type :||Observational|
|Estimated Enrollment :||160 participants|
|Official Title:||Dynamic Cardiac SPECT Imaging|
|Study Start Date :||March 2012|
|Estimated Primary Completion Date :||September 2015|
Patients scheduled to have clinically indicated stress MPI with low pre-test likelihood (0-15%) of coronary disease based on criteria of Diamond and Forrester. And those who have already had a clinical indicated stress MPI in the last three years with a low likelihood of having active coronary disease with no significantly narrowed coronary arteries.
Patients in Group II who will have the dynamic imaging protocol studies after SCA, patients will be selected for protocol enlistment only if the decision is made by the patient's physician, based totally on clinical and social factors, that any considered revascularization intervention would not be performed on the day of diagnostic selective coronary angiography (SCA) and will be performed electively, at least 4 to 7 days later. Viability will be assessed in these patients only in the presence of WM abnormalities, and with serial analysis of WM, as described above. Patients will be followed for death or infarction or other events more than 3 months after study, for up to 3 years following participation in the protocol.
Patients found at SCA to have lesions of "borderline" clinical significance, preferably in the absence of other associated lesions.
Patients who were diagnosed with advanced heart failure including patients who had or will have cardiac resynchonization therapy (CRT) or a heart transplant.
- Coronary Flow Reserve [ Time Frame: Length of procedure- 90 min ]The coronary flow reserve will be measured by comparing the rest and stress exams on the dynamic SPECT scans using developed algorithms. The accuracy will be compared with clinical PET, coronary angiography, and clinical SPECT.
