About this study

Official title: Daily Physical Activity at Pulse Pressure Above an Individual Threshold in Patients With Continuous Flow Left Ventricular Assist Devices - a Feasibility Study

Pilot study in patients with continuous flow left ventricular assist device (cfLVAD) to proof the feasibility of a specific individual training at home aimed to increase pulse pressure above a predefined threshold which might attenuate the loss of arterial wall thickness.

Hypothesis:

Increasing daily physical activity near to normal (> 10.000 steps per day) with a pre-defined level of pulse pressure (intensity) is a realizable and feasible approach to investigate changes in arterial wall thickness and cardio-respiratory capacity in cfLVAD patients.

Read the detailed description

The investigators will study 3 cfLVAD patients with low pulse pressure during work package 1 using two different exercises, treadmill and bicycle. Walking and cycling present the most commonly used physical activities which are applicable to most individuals on a daily basis. The investigators aim to demonstrate that individual changes of pulse pressure during these types of exercise can be assessed in cfLVAD patients.

In a feasibility study (work package 2) the investigator will enroll 6 cfLVAD patients to perform home-based physical activity programs including walking a defined number of steps per day with a predefined speed and cycling with a predefined power [watt] on a bicycle ergometer. The performance of the patients will be monitored over seven days using a wearable activity device.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Daily physical activityBehavioural

    A combination of walking (> 10.000 steps per day) and cycling on a stationary bicycle at home at an individual intensity. For the activity walking patients need to walk at a certain speed (e.g. 3 km/h) in order to be in the range of pulsatility as obtained from their pre-training treadmill test. For cycling a defined power in watt and duration will be given to each patient as defined from the pre-training cycling test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline in brachial artery smooth muscle thickness

    Unit: mm

    Measured: At baseline and after 2 months

Secondary outcomes (4)
  1. Change from baseline in peak oxygen consumption

    Unit: ml/min/kg

    Measured: At baseline and after 2 months

  2. Change from baseline in pulse pressure during rest and exercise

    Unit: mm/Hg

    Measured: At baseline and after 2 months

  3. Change from baseline in daily physical activity

    Unit: Steps per day assessed with a wearable activity device

    Measured: At baseline, after week 3, week 6, and after 2 months

  4. Change from baseline in quality of life questionnaire (SF-36)

    Unit: points

    Measured: At baseline and after 2 months

Questions about this trial

What is this clinical trial studying?

A study testing Daily physical activity in people with Heart Failure, run by Hannover Medical School at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in brachial artery smooth muscle thickness (time frame: At baseline and after 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2015.
