Lungs in Heart Failure

Figure 1

Lung function at rest in 190 heart failure patients in stable clinical condition. Patients were grouped according to exercise capacity. From left to right: peak VO₂ < 12 mL/min/kg (black bars), peak VO₂ = 12–16 mL/min/kg (white bars), peak VO₂ = 16–20 mL/min/kg (grey bars), and peak VO₂ > 20 mL/min/kg (dashed bars). FVC: forced vital capacity; FEV1: forced expiratory volume 1 second; DLCO: lung diffusion for carbon monoxide. Data from [8, Table 1].
