Summary

Despite advances in treatment and corresponding improvements in survival, patients with pulmonary arterial hypertension (PAH) remain highly symptomatic. In one survey of 315 patients with PAH, sixty-eight percent had moderate or severe dyspnea on exertion and 40% had a profound and clinically significant deficit in quality of life. Palliative care is being increasingly investigated in life-limiting cardiovascular diseases to alleviate symptoms. In PAH, its implementation is frequently delayed until end-of-life. Opioids are a common palliative care intervention, however the efficacy and safety of opioids for symptom relief in PAH has not been evaluated.
