About this study

Official title: Effects of Chronic Remote Ischaemic Conditioning on Coronary and Peripheral Vascular Function in Patients With Heart Failure

This study will test the impact of remote ischaemic conditioning combined with exercise on myocardial perfusion in patients with or at risk of heart failure

Read the detailed description

Heart failure (HF) is a disease which affects the heart's ability to pump or fill with blood. It can affect a person's quality of life and their ability to exercise. Recent work has shown that a reduction in the blood supply to the heart may contribute to the problem. It is therefore possible that improving the blood supply to the heart may help patients with HF. One possible way that this might be achieved is with a method called remote ischaemic conditioning (RIC). This involves placing a cuff on a person's arm (identical to a blood pressure cuff) and inflating it for a few minutes to reduce the blood flow in a person's arm. This is thought to release chemicals into the bloodstream which can have positive effects on the heart. This has been studied in patients with other forms of heart disease, but is yet to be tested properly in patients with heart failure. It is hypothesized that combining the RIC procedure with a low level of arm exercise may result in further improvements in the person's blood vessels and heart. This will be tested in a single-centre prospective study.

What participants receive

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

  • Remote Ischaemic Conditioning with exerciseDevice

    Participants will receive RIC through an automated device that will provide cycles on ischaemia/reperfusion to the target organ (arm). During the cuff deflation phase, participants will undergo handgrip exercise at 20-30% of their maximal voluntary contraction for 3 minutes. There will be a total of 4 cycles of exercise.

  • Other: Remote Ischaemic ConditioningDevice

    Participants will receive RIC through an automated device that will provide cycles on ischaemia/reperfusion to the target organ (arm).. There will be a total of 4 cycles.

Questions about this trial

What is this clinical trial studying?

A study testing Remote Ischaemic Conditioning with exercise and Other: Remote Ischaemic Conditioning in people with Heart Failure With Preserved Ejection Fraction and Type 2 Diabetes, run by University of Leicester at 1 site in United Kingdom.

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 3 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 27 Sep 2024. 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 United Kingdom. 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?

Results are not available in the source record.

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

Contact Jayanth Arnold, BMBCh DPhil (+44 1162583038, jra14@leicester.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Myocardial perfusion reserve (time frame: 4 weeks). The study lists 3 primary outcomes in all. 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 27 Sep 2024.
