  Purpose

Purpose of this study is to investigate whether and to what extent a cautious breath and movement therapy can complement medical treatment and the condition, oxygen uptake, quality of life, the pulmonary vascular pressures, the size of the right heart and the 6-minute walk distance in patients with pulmonary hypertension.

Further study details as provided by Heidelberg University:

Primary Outcome Measures:
  • Improvement of peak O2 uptake (VO2peak) under stress [ Time Frame: 15 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes in hemodynamics [ Time Frame: up to 15 weeks ] [ Designated as safety issue: No ]
    1. Changes in hemodynamics at rest and during exercise after three weeks and 15 weeks: RAP, RVP, sPAP, DPAP, mPAP, PCWP, cardiac output, PVR, CI, SvO2
    2. Changes in exercise capacity: 6-minute walk distance, Recumbent Bike (Watts), respiratory economy (EQO2, EQCO2)
    3. Improved condition(NYHA class, Borg scale)
    4. Changes in MRI and echocardiographic parameters of right and left ventricle: size and pump function.
    5. Change of laboratory parameters, which are markers of right heart failure as NTproBNP, interleukins

Arms Assigned Interventions
Experimental: Respiratory and exercise therapy
Randomized, prospective, controlled, blinded study of postoperative three-week inpatient rehabilitation and subsequent continuing of the training at home for 12 weeks. The control group received conventional postoperative rehabilitation without a specific training program.
Behavioral: respiratory and exercise therapy
Conventional therapy with diet, massage, relaxation baths, plus easy strolls specific respiratory and physical therapy plus mental walking training
No Intervention: respiratory and exercise therapy Behavioral: respiratory and exercise therapy
Conventional therapy with diet, massage, relaxation baths, plus easy strolls specific respiratory and physical therapy plus mental walking training
