Trial summary

Previous studies have evaluated the effects of inspiratory muscle training in patiens with heart failure and reduced ejection fraction; nevertheless,no evidence endorse the therapeutic role of inspiratory muscle training in patients with heart failure and preserved ejection fraction.

About this study

Previous studies have evaluated the effects of inspiratory muscle training in patiens with heart failure and reduced ejection fraction; nevertheless,no evidence endorse the therapeutic role of inspiratory muscle training in patients with heart failure and preserved ejection fraction. The investigators sought to evaluate whether 12-week inspiratory muscle training improves exercise capacity (peak exercise oxygen uptake and 6-minutes walk test), as well as left ventricular diastolic function, serum biomarkers and quality of life (Minnesota Living With Heart Failure Questionnaire) in patients with heart failure with preserved ejection fraction and non-reduced inspiratory muscle strength.

What participants receive

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

  • Inspiratory muscle trainingOther

    Patients were instructed to train at home twice daily for 20 minutes each session during 12 weeks with a threshold inspiratory muscle trainer (Threshold IMT®, Respironics Inc.). All of them were trained under the supervision of a physiotherapist and educated to maintain diaphragmatic breathing during training. The subjects started breathing at a resistance equal to 25-30% of their maximum inspiratory pressure for 1 week.

What is being measured

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

  1. Changes in exercise capacity parameters at 12-weeks.

    Exercise parameters: peak exercise oxygen uptake (peak VO2), 6-minutes walk test

    Measured: 12 weeks

Secondary outcomes (1)
  1. Changes in 12-week quality of life, biomarkers related to the severity and parameters of left ventricular diastolic function.

    Quality of life: Minnesota Living With Heart Failure Questionnaire. Biomarkers: plasma natriuretic peptides, estimaated glomerular filtration rate, antigen carbohydrate 125.

    Diastolic function: E/e´.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Inspiratory muscle training in people with Heart Failure, run by Fundación para la Investigación del Hospital Clínico de Valencia at 1 site in Spain.

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 8 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 4 Feb 2016. 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 Spain. 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?

Changes in exercise capacity parameters at 12-weeks. (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01707277, which also lists 3 linked publications.

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 4 Feb 2016.
