Table 5 Difference between main heart failure parameters on admission and at discharge.
| HF parameter | Admission (mean, 95% CI) | Discharge (mean, 95% CI) | Wilcoxon test p-value |
|---|---|---|---|
| NT-proBNP (pmoL/L) | 283.9 (261.24–306.48) | 192.9 (160.94–224.87) | |
| 6MWD (meters) | 271.32 (259.62–283.02) | 330.04 (309.34–350.74) | |
| TFC (1/kOhm) | 41.951 (9.9362–11.2062) | 37.274 (36.204–38.344) | |
| TFCI (1/kOhm/m) | 21.280 (20.513–22.047) | 18.873 (18.2–19.6) | |
| CO (mL/m) | 5.537 (5.307–5.767) | 5.879 (5.59–6.17) | |
| SI (mL/m) | 36 (34.74–37.26) | 40.2 (38.1–42.3) | |
| STR | 0.4167 (0.3991–0.4343) | 0.3932 (0.373–0.414) | |
| LCW (kg×m) | 6.688 (6.35–7.026) | 6.987 (6.85–7.39) | 0.767 |
| LCWI (kg×m/m) | 3.282 (3.14–3.42) | 3.388 (3.23–3.54) | |
| NT-proBNP – amino-terminal pro-brain natriuretic peptide; 6MWD – 6-min walk distance; TFC – thoracic fluid content; TFCI – thoracic fluid content index; CO – cardiac output; SI – systolic index; STR – systolic time ratio; LCW – left cardiac work; LCWI – left cardiac work index. | |||
