Trial summary

Heart failure is a condition that occurs when the heart muscle weakens and no longer contracts normally. Half of these patients have an irregularity of heart rhythm called atrial fibrillation (AF). Patients with both heart failure and AF spend more time in hospital, and die earlier than those with heart failure alone. Read more about this study

About this study

Official title: Radiofrequency Ablation for Atrial Fibrillation in Advanced Chronic Heart Failure

Heart failure is a condition that occurs when the heart muscle weakens and no longer contracts normally. Half of these patients have an irregularity of heart rhythm called atrial fibrillation (AF). Patients with both heart failure and AF spend more time in hospital, and die earlier than those with heart failure alone. AF is difficult to treat with conventional methods in patients with heart failure. Radiofrequency ablation is a new technique used to cure AF. The investigators aim to establish if radiofrequency ablation for atrial fibrillation in patients with advanced heart failure can result in marked improvement in the function of the heart.

Being tested
radiofrequency ablation, ACE inhibitor - ramipril, enalapril, captopril, perindopril, lisinopril, Beta Blocker (BB) - metoprolol, bisoprolol, carvedilol, Aldosterone Antagonists - spironolactone

What is being measured

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

  1. Change in Left Ventricular Ejection Fraction by Magnetic Resonance Imaging (MRI)%

    left ventricular ejection fraction (LVEF) is a measure of the % of blood ejected from the ventricle in one heart beat. It is a measure of cardiac function. We measured LVEF at baseline and at 6 months, to assess whether there had been a change in the patients cardiac function over time.

    Measured: baseline and 6 months

  2. Baseline Left Ventricular Ejection Fraction by Magnetic Resonance Imaging (MRI)

    Baseline Left Ventricular Ejection Fraction by Magnetic Resonance Imaging (MRI)in %

    Measured: Baseline

  3. Left Ventricular Ejection Fraction by Magnetic Resonance Imaging (MRI)at 6 Months

    Left Ventricular Ejection Fraction as measured by Magnetic Resonance Imaging (MRI)at 6 months

    Measured: 6 months

Secondary outcomes (3)
  1. Plasma B-type Natriuretic Peptide (BNP)

    venous blood taken to assess levels of the above peptide. High evels of the peptide are associated with adverse prognosis. Blood levels are taken at baseline and 6 months. The change over 6 months is assessed, thereore it is possible to have a negative number if the level falls.

    Measured: baseline and 6 months

  2. Plasma B-type Natriuretic Peptide (BNP) at Baseline

    Plasma B-type Natriuretic Peptide (BNP) measured at basline

  3. Plasma B-type Natriuretic Peptide (BNP) at 6 Months

Questions about this trial

What is this clinical trial studying?

A study testing radiofrequency ablation, ACE inhibitor - ramipril, enalapril, captopril, perindopril, lisinopril and Beta Blocker (BB) - metoprolol, bisoprolol, carvedilol in people with Chronic Heart Failure and Atrial Fibrillation, run by NHS Greater Glasgow and Clyde 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 5 inclusion and 10 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 1 Jun 2012. 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?

Yes. Results are posted in the registry (first posted 1 Jun 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Left Ventricular Ejection Fraction by Magnetic Resonance Imaging (MRI)% (time frame: baseline and 6 months). 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?

On the ClinicalTrials.gov record for NCT00292162, 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 1 Jun 2012.
