About this study
This study will collect information about physical activity in patients affected by pulmonary hypertension, through a specific device that can be worn on the wrist, and which measures daily step count. The purpose of the study is to demonstrate whether providing patients with their daily step count can increase their levels of daily activity if they have some basic targets to achieve. Investigators also wish to compare the effects of this approach in increasing daily physical activity, with the benefit gained when a drug therapy for pulmonary hypertension is initiated, in patients that have just been diagnosed.
Read the detailed description
Pulmonary hypertension (PH) is a rare and progressive disorder and shortness of breath and fatigue, especially during exercise, are very common symptoms, resulting in a reduced capacity to perform daily activities and in an impaired quality of life. Furthermore, reduced exercise capacity in PH is associated with depression and anxiety disorders. Recent literature reveals a strong association of sedentary time with adverse cardiovascular outcomes, so that the development of therapeutic strategies to avoid this event is pivotal in the management of PH, in addition to the beneficial results of modern medical treatment. Recently the role of exercise and rehabilitation in different respiratory and cardiac conditions has been evaluated in the literature, overtaking the concerns raised in the past that exercise could worsen the condition and thus the progression of these kind of diseases, but just a few studies have been done in patients affected by PH.
International guidelines on pulmonary hypertension recommend avoiding strenuous exercise that leads to distressing symptoms, while encourage low level graded aerobic exercise, such as walking, as tolerated. Nonetheless, little is still known about the effects of lifestyle changes, such as the amount of physical activity that patients can or should practice. Pedometers have been used to enhance the daily physical activity and to improve, when assessed, some prognosis related outcomes, both in healthy subjects and those affected by different pathological conditions, in particular cardiac and respiratory diseases. However, a training model based on step count targets has never been evaluated in PH, to our knowledge. Step counting devices have recently experienced a surge in popularity as a tool for motivating and monitoring physical activity in the general population, especially combined with applications for smartphones, that provide feedback, such as an overview of the data recorded. Thus, it seems reasonable to explore the opportunity to develop a step count based training model to enhance daily exercise in PH patients, through these non-invasive, patient friendly and relatively inexpensive devices.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Actigraph GT9X Link deviceDevice
Assessment of the level of physical activity of PH patients using the Actigraph GT9X Link device that includes a triaxial accelerometer and can be enabled to show on its display the number of steps taken for the day, so that it can also be used by the patients as a common pedometer.
Evaluation of the effects of an 8 week step count-based light touch training programme to see if activity can be increased
| Study group | Role | What they receive |
|---|---|---|
| feedback and goal-setting group | Active comparator | At the baseline, patients will fill a questionnaire about their quality of life (SF36), will perform a 6'walk test (6MWT), will undertake a blood sample (BNP). In the run-in period (1 week) patients will wear an Actigraph GT9X Link device which only displays the time and the battery level; all activity data will be recorded. Then participants will wear an Actigraph GT9X Link device which shows real time data about the number of steps and will upload their data via the Study Admin Mobile application for smartphones/tablets. Patients will be asked to aim for an average specified number of steps/day week by week and will receive a weekly report with results from the previous week and targets to achieve. After 8 weeks, patients will attend visit 2 (6MWT, SF36 and BNP assessment) and will carry on wearing the activated device for 8 weeks receiving weekly feedbacks and targets. After 8 weeks patients will attend visit 3 (6MWD, SF36 and BNP will be assessed) which is the end of the study. Receives: Device: Actigraph GT9X Link device |
| Control group | Active comparator | At the baseline, patients will fill a questionnaire about their quality of life (SF36), will perform a 6'WT and will undertake a blood sample (BNP). After a run-in period (1 week) with an Actigraph GT9X Link device disabled from showing the number of steps, patients will wear an Actigraph GT9X Link device which still only displays time and battery level and will upload data via the Study Admin Mobile application for smartphones/tablets without receiving any feedback. After 8 weeks, patients will be assessed (SF36, 6'WT, BNP) and will start to wear a new device enabled to display the daily step count. Patients will be asked to aim for an average specified number of steps/day, receiving a weekly summary of the previous week with targets to achieve week by week. After 8 weeks, patients will be assessed (6'WT, SF36, BNP) and will carry on wearing the device and receiving feedbacks and targets for a further 8 week period, after that patients will be finally assessed (SF36, 6'WT, BNP) Receives: Device: Actigraph GT9X Link device |
| newly diagnosed patients | Placebo comparator | In the week leading up to their inpatient admission for diagnostic investigations, patients who are treatment-naïve will be given the Actigraph GT9X Link device which will only display the time and the charge level of the battery. Patients will be asked, as well, to fill a questionnaire about their quality of life, to perform a 6MWT and a blood sample (BNP). As soon as patients start the drug therapy, patients will wear a second Actigraph GT9X Link device still disabled from showing real time data about the number of daily steps. Participants will not receive any feedback during the whole period and will be asked, as well, to upload the data collected through the remote mobile system. At their first clinical assessment (after about 4 or 5 weeks), 6'WT, BNP and questionnaire about quality of life will be reassessed.
If patients are not being started on drug therapy then they will be withdrawn from the study Receives: Device: Actigraph GT9X Link device |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in daily physical activity
The principal objective is to demonstrate a difference in the intensity of daily physical activity, measured in activity counts per minute, from the basal period to the last week of the 8-week training programme compared with control
Measured: From baseline to 16 - 25 weeks
Secondary outcomes (5)
Change in 6MWT
Evaluation of the difference in the 6MWT from the basal period to the end of the 8-week training programme compared with control
Measured: From baseline to 16 - 25 weeks
Change in BNP
Evaluation of the difference in BNP values from the basal period to the end of the 8-week training programme compared with control
Measured: From baseline to 16 - 25 weeks
Change in Quality of life
Evaluation of the difference in quality of life (assessed by SF36 questionnaire) from the basal period to the end of the 8-week training programme compared with control
Measured: From baseline to 16 - 25 weeks
Long-term effects of training protocol
Evaluate if the eventual benefit gained after the 8 week training period (measured in activity counts per minute) is maintained, reduced or increased for a further 8 week period (group1+ group 2).
Measured: End of the 8 week period
Comparison between training protocol and initiation of PH treatment in terms of increased physical activity
Comparing the efficacy of our training protocol to the effects of the initiation of the PH drug treatment in newly diagnosed patients, in terms of increased physical activity assessed in terms of activity counts.
