PURPOSE: Dyspnoea is the most common symptom of pulmonary arterial hypertension (PAH ). Up to 75 % of patients with PAH are diagnosed in advanced stages of the disease. Patients with PAH associated with systemic connective tissue (CTD) have a poor prognosis, especially patients with systemic sclerosis. Despite modern therapy is a maximum 3 -year survival less favorable than in other forms of PAH 51 % vs 87%. Early stages of PAH are characterized by abnormal hypertensive response of pulmonary circulation to exercise. The aim of our study was to examine exercise-induced changes in invasive pulmonary hemodynamics in patients with CTD and compare them to other patients with dyspnoea of unknown etiology.
