Performance of single photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) stress testing for detecting coronary artery bypass graft patency
Stress test Stress test adequacy Sensitivity (%) Specificity (%) PPV (%) NPV (%)
Exercise SPECT-MPI (n = 68) Adequate: MPHR > 80% (n = 26) 77 69 71 75
Inadequate: MPHR ≤ 80% (n = 42) 43 52 47 48
Pharmacologic SPECT-MPI (n = 11) 75 57 50 80

MPHR: Maximum predicted heart rate. PPV: Positive predictive value. NPV: Negative predictive value.
