Comparison of lung function parameters according to clinical presentation.
| Classical CPE | Cardiac asthma | |
| N = 41 | N = 26 | |
| FVC (L) | 1.77 ± 0.56 | 1.60 ± 0.73 |
| FVC (% predicted) | 67 ± 24 | 65 ± 26 |
| FEV1(L) | 1.33 ± 0,5 | 1.09 ± 0,49* |
| FEV1(% predicted) | 65 ± 23 | 58 ± 27 |
| FEV1/FVC ratio (%) | 71.2 ± 15.6 | 66.9 ± 14 |
| FEV1/FVC (% predicted) | 96 ± 21 | 90 ± 21 |
| PEF (L/min) | 172 (119 – 238) | 146 (100 – 206) |
| PEF (% predicted) | 47 (31 – 64) | 40 (30 – 55) |
| FEF25–75 (L/s) | 0.99 (0.68–1.77) | 0.76 (0.38–1.10)* |
| FEF25–75 (% predicted) | 48 (24–73) | 32 (18–51)* |
Data are mean ± SD, median (interquartile 25–75%); FVC: forced vital capacity, FEV: Forced Expiratory Volume In 1 Second, FEF25–75: forced expiratory flow at 25% to 75% of vital capacity; PEF rate: peak expiratory flow; *p < 0.05.
