Diagnostic and Prognostic Values of Previously Reported Thresholds
| Diagnosis of CAV grade 2/3 | Annualized all-cause mortality rate | ||||
| Cutoff | Abnormal (n) | Sensitivity | Specificity | Abnormal | Normal |
| MFR < 2.0 | 34 (34.3%) | 71.4% | 71.8% | 17.7% | 4.7% |
| MFR < 1.75 | 27 (27.3%) | 57.1% | 77.7% | 19.6% | 5.2% |
| Stress MBF < 3.7 | 79 (79.8%) | 92.9% | 22.4% | 9.0% | 6.7% |
| Stress MBF < 1.7 | 10 (10.1%) | 42.9% | 95.3% | 35.8% | 7.0% |
| SSS > 1 | 32 (32.2%) | 64.3% | 72.9% | 12.3% | 7.0% |
| SSS > 3 | 15 (15.2%) | 64.3% | 92.9% | 18.7% | 7.1% |
| LVEF ≤ 45 | 10 (10.1%) | 42.9% | 95.3% | 25.0% | 7.2% |
| MBF < 1.7 and SSS > 1 or LVEF ≤ 45 | 8 (8.1%) | 42.9% | 97.7% | 60.7% | 6.8% |
| SSS ≥ 4, LVEF ≤ 45 or MFR < 1.75 | 36 (36.4%) | 71.4% | 69.4% | 15.4% | 5.0% |
| LVEF ≤ 45% and MFR < 1.75* | 5 (5.1%) | 35.7% | 100.0% | 51.6% | 7.4% |
↵* Same patients would be identified using MBF < 1.7 and LVEF < 45%.
Uncorrected MFR was used because it was numerically superior in all models.
