Exercise Hemodynamics in Patients With Pulmonary Fibrosis
2018年10月11日 更新者：EVAGGELIA PANAGIOTIDOU、Aristotle University Of Thessaloniki
Hemodynamic Study of the Pulmonary Circulation in Exercise in Patients With Pulmonary Fibrosis
The study evaluates the rest and exercise hemodynamics of patients presenting either idiopathic fibrotic pulmonary disease or pulmonary fibrosis secondary to connective tissue disease.

详细说明
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.

Change in total pulmonary resistance (TPR) from rest to exercise
大体时间：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.
