Lung diffusion capacity in advanced heart failure: relation to central haemodynamics and outcome

Aims Patients with heart failure (HF) are known to have a reduced pulmonary diffusion capacity for carbon monoxide (DLCO), but little is known about how lung function relates to central haemodynamics. The aim of this study was to investigate the association between haemodynamic variables and pulmonary diffusion capacity adjusted for alveolar volume in congestive HF patients and to analyse how predicted DLCO/VA affects mortality in relation to the haemodynamic status.
