Exercise Hemodynamics in Patients With Pulmonary Fibrosis
Hemodynamic Study of the Pulmonary Circulation in Exercise in Patients With Pulmonary Fibrosis
Studieoversikt

Forhold
Detaljert beskrivelse
Patients with fibrotic pulmonary disease of the above origin will undergo detailed assessment of functional status with the following examinations: pulmonary function tests, echocardiogram, 6 minute exercise test, cardiopulmonary exercise test (in the absence of contra-indications) and finally right heart catheterization. Hemodynamic assessment will take place at rest and at exercise following the exercise protocol that was recommended by Herve et al (ERJ 2015) using a cycle ergometer at bedside.
The purposes of the study are:
- to evaluate the response of the hemodynamic parameters at exercise compared to the resting parameters in this patient group.
- to discriminate between precapillary from postcapillary etiology of pulmonary hypertension.
- to correlate non-invasive parameters of functional limitation with invasive hemodynamic parameters.
- to assess the prognostic role of exercise induced pulmonary hypertension in the specific patient group.

Beskrivelse
Inclusion Criteria:
- diagnosis of pulmonary fibrosis secondary to connective tissue disease, according to the American College of Rheumatology/European League Against Rheumatism (ACR-EULAR) revised classification criteria , or diagnosis of idiopathic fibrotic diffuse pulmonary disease according to American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines
- Forced vital capacity (FVC) ≥ 40 %
Exclusion Criteria:
- Presence of contra-indications to exercise tests, such as acute myocardial infarction, unstable angina, uncontrollable arrythmia or skeletal disease that limits the ability to exercise.

Tidsramme |
|---|---|---|
|
Change in total pulmonary resistance (TPR) from rest to exercise
Tidsramme: 2nd minute,4th minute, 6th minute, 8th minute
|
The patient undergoes right heart catheterization and all hemodynamic variables are measured at rest and at exercise.
TPR is derived by the following equation : mean pulmonary artery pressure/ cardiac output (mPAP/CO).
TPR is measured at rest and at exercise following a specific protocol.
The measurements are made at rest, then at the sequential exercise steps of increasing work resistance.
