Retrospective patient cohort
  • Diagnostic Test: assessment of pulmonary hemodynamics during exercise by right heart catheterization
    all patients undergo right heart catheterization during exercise due to clinical reasons. Results of this and other Routine clinical tests will be included in the registry
