Exercise oscillatory breathing (EOB) is a ventilatory abnormality that occurs in ∼20% of heart failure (HF) patients and carries a very unfavourable prognosis. Pulmonary vasoconstriction has been suggested to be involved in this disorder. We hypothesized that modulation of pulmonary vascular hypertone by oversignalling of the nitric oxide pathway with phosphodiesterase 5 (PDE5) inhibition might be beneficial. Accordingly, we performed a 1-year pilot trial with sildenafil in patients with HF and EOB.
