To clarify the relative contribution of resting haemodynamic profile and pulmonary function to exercise capacity in patients with heart failure. ⋯ The data confirm previous studies showing a poor correlation between resting indices of cardiac function and exercise capacity in heart failure. However, several pulmonary function variables were related to peak exercise VO(2). In particular, lung diffusing capacity and respiratory muscle function seem to affect exercise tolerance during heart failure.
