Summary

Dyspnea is a major symptom in pulmonary arterial hypertension and people with the same haemodynamic have generally different degree of dyspnea in pulmonary arterial hypertension. The hyperventilation syndrome is a frequent cause of dyspnea in general population and in respiratory diseases like asthma but has never been studied in pulmonary hypertension. The goal of this study is to measure the prevalence of pulmonary hypertension in a population of patients with controlled pulmonary arterial hypertension (PAH).

Detailed description

Hyperventilation syndrome has been described as a cause of dyspnea in the general population and in several chronic respiratory diseases such as asthma with 20 to 40% of asthmatics affected. However, Hyperventilation syndrome has never been sought in a population with PAH. Hyperventilation syndrome, although complex pathophysiology, may be simply corrected by a management of respiratory physiotherapy based on the control of respiration.
