| Parameter | AUC | Cutoff value | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) | Accuracy (%) |
|---|---|---|---|---|---|---|---|
| Hs-cTnI (ng/L) | 0.73 | >1.5 | 89.6 (43/48) | 81.8 (27/33) | 91.5 (43/47) | 79.4 (27/34) | 86.4 (70/81) |
| Stenotic extent (%) | 0.8 | ≥77.5 | 87.5 (42/48) | 87.9 (29/33) | 91.3 (42/46) | 82.9 (29/35) | 87.7 (71/81) |
| Preprocedural TIMI flow grade | 0.67 | ≤2 | 81.3 (39/48) | 87.9 (29/33) | 84.8 (39/46) | 82.9 (29/35) | 84 (68/81) |
PCI, percutaneous coronary intervention; AUC, area under curve; PPV, positive predictive value; NPV, negative predictive value; hs-cTnI, high-sensitivity cardiac troponin I; TIMI, thrombolysis in myocardial infarction.
