Brief Summary:
Purpose of this study is to investigate whether and to what extent a cautious respiratory 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.

Condition or disease Intervention/treatment Phase
CTEPH Behavioral: respiratory and exercise therapy Phase 3

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 90 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Influence of Respiratory and Exercise Therapy on Oxygen Uptake, Quality of Life and Right Heart Function in Chronic Thromboembolic Pulmonary Hypertension After Thromboendarterectomy
Study Start Date : January 2010
Estimated Primary Completion Date : December 2015
Estimated Study Completion Date : December 2015

Arm Intervention/treatment
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: no respiratory and exercise therapy
continuation of usual lifestyle

Primary Outcome Measures :
  1. Improvement of peak O2 uptake (VO2peak) under stress [ Time Frame: 15 weeks ]

Secondary Outcome Measures :
  1. Changes in hemodynamics [ Time Frame: up to 15 weeks ]
    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
