Summary

Pulmonary arterial hypertension (PAH) is a chronic illness characterized by increased pulmonary pressures resulting in right heart failure and premature death. Common symptoms that impair quality of life and functioning are dyspnea, fatigue and sleep disturbance. This trio of symptoms is highly prevalent and forms a symptom cluster (2 or more symptoms that co-occur) in PAH. From a biological, proinflammatory cytokines are implicated in dyspnea, fatigue and sleep disturbance; there is activation of the sympathetic nervous system (SNS) and an inherent inflammatory process in PAH that contributes to the pathophysiology, but the link to this symptom cluster has not been investigated. One novel, treatment for symptom clusters is slow-paced respiration therapy using the FDA-approved device, RESPeRATE. The device contains headphones and a sensor that attaches to the chest to detect inhalation and exhalation. Musical tones synchronize with the respiratory cycle to slowly guide the user to decrease respirations. RESPeRATE moderates effects of the SNS; lowers blood pressure; improves functional capacity and ejection fraction; and significantly decreases pulmonary pressures in left heart failure. The investigators will enroll 10 women with PAH to use the RESPeRATE device to perform slow-paced respiration for 15 minutes per day for 8 weeks to determine the feasibility and effects on the SNS and inflammatory activity and the symptom cluster. The investigator's overall hypothesis is that, as compared to baseline, after eight weeks of therapy women with PAH who receive slow-based respiration therapy will have lower SNS activity and inflammatory levels, and improved dyspnea, fatigue and sleep disturbance.
