Non-isotope Based Imaging Modalities vs Technetium-99m Single-Photon Emission Computed Tomography(99mTcSPECT) (MITNECB5)
20 februari 2020 uppdaterad av: Montreal Heart Institute
Non-isotope Based Imaging Modalities vs 99mTcSPECT to Detect Myocardial Ischemia in Patients at High Risk for Ischemic Cardiovascular Events
SPECT is currently the dominant clinical test for diagnostic and prognostic purposes as well as therapeutic decision-making.
Given the shortage of nuclear reactor-produced Tc, advancing the use of non-isotope based imaging modalities has the potential to change the standard of care for patients with CAD as each one of these technics (CMR, CT, Stress echocardiography) has its own distinct potential advantages over SPECT.

Betingelser
Detaljerad beskrivning
Obtain a better understanding of the clinical utility of advanced non-isotope-based imaging modalities to detect relevant CAD as potential alternatives to SPECT.
Approximately 450 subjects will be enrolled in total.
Three groups of about 150 patients per group.
Each group will undergo imaging with 2 modalities; Group 1: 99mTcSPECT plus CMR, Group 2: 99mTcSPECT plus CT, Group 3:99mTcSPECT plus stress echocardiography.
All 450 patients will undergo standard invasive coronary angiography following completion of non-invasive imaging, except for patients in whom both nuclear and non-nuclear imaging modalities reveal a normal result confirming the absence of significant coronary artery disease (i.e invasive angiography would not be clinically indicated and FFR would be considered to be above 0.8).
Thrombolysis in Myocardial Infraction (TIMI) flow will be measured in all patients undergoing angiography, and fractional flow reserve (FFR) will be measured in all patients except those with TIMI flow =0, 1 and 2. All imaging procedures must be completed within 6 weeks.
All patients will have a follow-up visit at 6 months after enrollment.
During the 6 month follow-up visit major adverse cardiovascular events will be collected and adjudicated by a clinical endpoint committee (CEC).

Studera befolkning
Approximately 450 patients across Canada.
Patients will be identified after a clinically indicated SPECT for evaluation of myocardial ischemia.The investigator will assign the patient in one of the three groups based on his medical assessment and availability of equipment at the centre.

Tidsram |
---|---|---|
Overall accuracy of "significant coronary artery disease (CAD)" according to non-invasive imaging modality
Tidsram: baseline
|
The overall accuracy is calculated as the probability that a subject is correctly classified (presence of significant CAD or not) by non-invasive imaging modality.
The standard of truth is presence of significant CAD or not according to the invasive fractional flow reserve (FFR)
