Overview
Brief Summary
Concordance between walking tests and pedometer data may seem like a logical outcome for pulmonary hypertension (PH) patients. However, many individuals have discordant results: results much worse or better during an in-hospital walking test as compared to real life activity.
The primary objective of this study is: to determine variables associated with discordance between the distance walked during an in-hospital 6-minute walking test (6MWT) and the average distance travelled per day (observed over a period of 28 days (2 × 14 days) using a pedometer) among PH patients.
Detailed Description
Secondarily, the discordance between 6MWT results versus total pedometer recorded distance and versus maximum daily pedometer-recorded distance will be similarly studied. The aim of the study is also to search for variables associated with progression free survival. The relationships between pedometer data and self-reported dyspnea variation will be studied. Factorial analysis may be used to study the overall view of variable correlations and patient similarity/dissimilarity.

Outcomes
Primary Outcomes
The patient's discordance category as precisely defined here:
Time Frame: 74 days
Linear regression is performed for the distance walked during an initial 6 minute walking test (6MWT) and the average distance walked per day according to the pedometer intervention. The residuals from this regression will determine categories: Category 1 (pedometer high): the 25% of subjects not in category 2 and with higher values for pedometer data Category 2 (concordance): the 50% of included subjects with the smallest residuals in terms of absolute value. Category 3 (6MWT high): the 25% of subjects not in category 2 and with higher values for 6MWT data
Secondary Outcomes
- Coping with Health Injuries and Problems Scale(Month 3)
- Multidimensional Fatigue Inventory (MFI)-20 questionnaire(Month 3)
- Health related quality of life questionnaire (the Medical Outcome Study - Short Form (SF36))(Month 3)
- Hospital Anxiety and Depression (HAD) scale(Month 3)
- State-Trait Anxiety Inventory (STAI) questionnaire(Month 3)
