Table 4 Accuracy of single photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) stress testing for detecting coronary artery bypass graft disease according to the territory that is supplied by the diseased graft
From: Utility of nuclear stress imaging for detecting coronary artery bypass graft disease
Stress test | Stress test adequacy | Accuracy-Overall (%) | Accuracy-Anterior (%) | Accuracy-Lateral (%) | Accuracy-Inferior (%) |
|---|---|---|---|---|---|
Exercise SPECT-MPI (n = 68) | Adequate: MPHR > 80% (n = 26) | 73 | 81 | 76 | 78 |
Inadequate: MPHR ≤ 80% (n = 42) | 48 | 83 | 55 | 54 | |
Pharmacologic SPECT-MPI (n = 11) | 64 | 55 | 80 | 63 | |
