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 |
