Standard pulmonary function and lung diffusion tests in the whole study population
| Heart failure patients (n=40) | Normal controls (n=40) | |
|---|---|---|
| Data are presented as mean (SD). | ||
| *p < 0.01 v normal controls. | ||
| Dm, molecular diffusion for carbon monoxide across the alveolar capillary membrane; FEV1, forced expiratory volume in one second; FVC, forced vital capacity; MVV, maximum voluntary ventilation; pred, Tlco, lung transfer capacity for carbon monoxide; Vc, capillary blood volume. | ||
