C-statistics for the prediction of LVEF ≤ 40%.
| Variables | AUC | 95% CI | p-Value | AUC Increment | ROC Comparison |
|---|---|---|---|---|---|
| Admission CRP | 0.53 | 0.48–0.58 | 0.383 | - | - |
| 24 h CRP | 0.73 | 0.69–0.77 | <0.001 | 0.20 | <0.001 |
| CRPv | 0.77 | 0.72–0.81 | <0.001 | 0.04 | <0.001 |
| Peak CRP | 0.77 | 0.73–0.81 | <0.001 | <0.01 | 0.807 |
| Peak cTnT | 0.77 | 0.73–0.81 | <0.001 | <0.01 | 0.905 |
| CRPv and peak cTnT | 0.81 | 0.77–0.85 | <0.001 | 0.04 | 0.009 |
AUC = area under the curve, CI = confidence interval, CRP = C-reactive protein, cTnT = cardiac troponin T, LVEF = left ventricular ejection fraction, ROC = receiver operating characteristic.
