Study Overview
Brief Summary
In Patients with rheumatic disease exercise training is a well established element of therapy. In contrast patients with severe pulmonary hypertension are advised to avoid physical exertion and must not perform exercise training. This study aims to evaluate the effectivity and safety of a low-dose training program in patients with pulmonary hypertension and rheumatic disease.

Outcomes
Primary Outcomes
Change in the 6-minute walking distance
Time Frame: after 3 weeks and after 15 weeks compared to baseline.
Quality of life (SF-36)
Time Frame: baseline and 15 weeks
Secondary Outcomes
- Physical capacity in the cardiopulmonary exercise testing (Watt)(baseline, 3 weeks, 15 weeks)
- change of peak oxygen consumption and other parameters of cardiopulmonary exercise testing.(baseline, 3 weeks, 15 weeks)
