Table 8 Predictive value of the main heart failure parameters.
| Parameter (p<0.001) | TFC ≥36.9 1/kOhm | TFC ≥36.9 1/kOhm +LVEF ≤40% | TFC ≥36.9 1/kOhm +NT-proBNP ≥425.5 pmoL/L |
|---|---|---|---|
| Sensitivity (%), (n) | 80.5 (103/128) | 77.8 (84/108) | 86.7 (39/45) |
| Specificity (%), (n) | 55.5 (92/173) | 53.0 (60/113) | 54.8 (92/168) |
| Positive predictive value (%), (n) | 57.2 (103/180) | 77.8 (84/108) | 97.5 (39/40) |
| Negative predictive value (%), (n) | 79.3 (96/121) | 98.4 (60/61) | 82.9 (92/111) |
| Predictive accuracy (%), (n) | 66.0 (199/301) | 85.2 (144/169) | 86.8 (131/151) |
| TFC – thoracic fluid content; LVEF – left ventricular ejection fraction; NT-proBNP – amino-terminal pro-brain natriuretic peptide. | |||
