About this study

Official title: The INCA Study: Inspiratory Muscle Training in Patients With Chronic Heart Failure

The purpose of this study is to determine whether a high intensity short duration inspiratory muscle training is feasible, secure and effective to improve respiratory muscle function (strength and resistance), health-related quality of life, and to assess potential correlations with health resources utilization.

Read the detailed description

Patients with chronic heart failure (CHF) often refer exercise intolerance, marked fatigue and dyspnea at low exercise intensities. This characteristic feature might be generated by respiratory and skeletal muscle dysfunction, and it´s has been described as a comorbid status, reflecting the systemic impact of heart failure. Despite the availability of effective pharmacologic treatments, patients with CHF continue to experience progressively worsening symptoms, frequent hospital admission and premature death. Reduced physical functioning, role limitation, and lack of energy may interfere with daily activities as the condition worsens and thereby severely reduce the quality of life in CHF patients. The ACCF/AHA Guidelines for the diagnosis and management of heart failure recommend exercise training as an adjunctive approach to improve clinical status in stable adult patients with current or prior symptoms of heart failure and reduced left ventricular ejection fraction. A wide variety of studies have focussed on respiratory muscles abnormalities in CHF patients. Reduced strength and endurance of respiratory muscles are currently recognized as additional factors implicated in the limited exercise response and quality of life, as well as in a poor prognosis. Additionally, inspiratory muscle training (IMT) has shown to result in improvements on inspiratory strength, functional capacity, ventilatory response to exercise, recovery oxygen uptake kinetics, and quality of life of CHF patients with respiratory muscle weakness. The optimal training scheme remains still to be defined. Most of clinical trials have demonstrated the effectiveness of a low-intensity IMT (maximum 38 cmH2O), but there is little information of the training effects when using higher training loads. Our research group has demonstrated that a short-time high-intensity respiratory training in patients with chronic obstructive pulmonary disease afford to reach good functional results in a shorter time, which affords to make more efficient in terms of time the rehabilitation program and to reach to more patients.

Questions about this trial

What is this clinical trial studying?

A study testing High-intensity IMT in people with Chronic Heart Failure, run by Parc de Salut Mar 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 3 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 17 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?

Change in respiratory muscle function strength (time frame: Baseline to 4 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 NCT01606553, which also lists 1 linked publication.

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 17 Feb 2016.
