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.
Secondarily, the discordance between 6MWT results versus total pedometer recorded distance and versus maximum daily pedometer-recorded distance will be similarly studied. We will also 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.

The Six Minute Walking Test (6MWT) efficiently represents the exercise capacity in subjects with chronic respiratory disease, as asthma. The variation of the walking distance is a paramete...
To compare the relationship between breath-hold time and the distance in a Six Minute Walking Test in chronic obstructive pulmonary disease population.
This study will determine if a rehabilitation exercise program can help people with pulmonary hypertension (PH) increase their physical activity. Patients with PH have an increase in bloo...
Comparing the effects of upper limb and breathing exercises on six-minute walking distance among patients with chronic obstructive pulmonary disease: a three-group randomized controlled clinical trial.
Physical exercise can improve patient outcomes and reduce hospitalization and mortality rates among subjects with chronic obstructive pulmonary disease. This study aimed to compare the effects of uppe...
The 6-minute walk (6 MW) is the most commonly applied measure of endurance walking capacity in persons with multiple sclerosis (MS); however, we are not aware of a quantitative synthesis of 6 MW p...

An activity in which the body advances at a slow to moderate pace by moving the feet in a coordinated fashion. This includes recreational walking, walking for fitness, and competitive race-walking.
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
Familial or idiopathic hypertension in the PULMONARY CIRCULATION which is not secondary to other disease.
A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
The amount of a gas taken up, by the pulmonary capillary blood from the alveolar gas, per minute per unit of average pressure of the gradient of the gas across the BLOOD-AIR BARRIER.
