Myocardial InfarctionPhase 4NCT00132093
Effects of Eplerenone on Left Ventricular Remodelling Following Heart Attack
A Phase 4 study testing Eplerenone in people with Myocardial Infarction, run by NHS Greater Glasgow and Clyde at 1 site in United Kingdom.
Trial summary
The purpose of this study is to ascertain whether treatment with the drug eplerenone, taken early after a heart attack, prevents or reduces some of the adverse changes that may otherwise naturally occur within the heart muscle, that lead ultimately to weakening of the heart muscle and premature death.

About this study
Official title: The Effects of Eplerenone on Left Ventricular Remodelling Post-Acute Myocardial Infarction: a Double-Blind Placebo-Controlled Cardiac MR-Based Study
The purpose of this study is to ascertain whether treatment with the drug eplerenone, taken early after a heart attack, prevents or reduces some of the adverse changes that may otherwise naturally occur within the heart muscle, that lead ultimately to weakening of the heart muscle and premature death.
Read the detailed description
Despite advances in detection and treatment of coronary artery disease, and numerous campaigns to promote healthier lifestyles, ischaemic heart disease (IHD) remains very common worldwide but particularly in the West of Scotland. Following a heart attack, the main pumping chamber - the left ventricle (LV) - will be significantly damaged in around 40% of patients to the extent that it fails to pump as effectively as before. Despite current medical treatment, this failing LV slowly but continuously deteriorates with time (this is known as LV remodelling), which can lead to "heart failure".
Eplerenone, a hormone blocker (aldosterone antagonist), has been shown to reduce death rates and improve symptoms in patients with acute heart attacks - or myocardial infarctions (MI)- who additionally have impaired LV function and heart failure (or diabetes). The researchers assume that eplerenone may exert some of these beneficial effects by preventing or reducing this LV remodelling process.
Cardiac MRI provides very accurate assessment of LV function, such that small numbers of patients only are required to detect differences in LV function over time when comparing one group against another. The researchers are therefore comparing sequential cardiac MRI appearances and measurements in patients with acute MI and LV impairment at baseline (within 2 weeks of the acute MI), 3 months and 6 months. After the first MRI scan, patients are assigned to eplerenone or placebo in addition to usual secondary preventive therapy (double-blinded), which continues for 6 months, after which each patient's involvement in the trial is finished.
As eplerenone has been shown to benefit those with acute MI plus LV impairment and heart failure (or diabetes), such patients cannot ethically be put into a trial in which they may potentially be placed in a placebo group. For this reason, a slightly different cohort of patients are being used - acute MI with LV impairment but without clinical heart failure or diabetes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in left ventricular (LV) end-systolic volume over 6 months, based on cardiac magnetic resonance imaging (MRI) measurements, comparing treatment group to placebo group
Secondary outcomes (4)
Comparison of lab blood markers of LV remodelling over 6 months, comparing treatment group to placebo group

Comparison of cardiac electrical stability (heart rate variability, QT dispersion) over 6 months, comparing treatment group to placebo group
Analysis of DNA at baseline between and within the eplerenone group and the control group - to see if mutations in the gene that encodes aldosterone synthase - CYP112B - predict remodelling and response to aldosterone blockade

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Eplerenone in people with Myocardial Infarction, 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 4 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 10 Apr 2006. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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 left ventricular (LV) end-systolic volume over 6 months, based on cardiac magnetic resonance imaging (MRI) measurements, comparing treatment group to placebo group. 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 NCT00132093, which also lists 11 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 10 Apr 2006.
