Trial summary

Despite recent improvements in treatment, myocardial infarction (heart attack) is still a leading cause of illness and death in the UK. Following the acute event, it is difficult to predict which patients are at risk of further problems, such as heart failure and is therefore difficult to know which patients need more… Read more about this study

About this study

Official title: Determination of the Time Course of Myocardial Oedema Post Myocardial Infarction Treated With Primary Angioplasty Using Cardiac Magnetic Resonance Imaging

Despite recent improvements in treatment, myocardial infarction (heart attack) is still a leading cause of illness and death in the UK. Following the acute event, it is difficult to predict which patients are at risk of further problems, such as heart failure and is therefore difficult to know which patients need more aggressive/intensive treatment and monitoring.

There needs to be a test which is safe, reliable and reproducible that can be used shortly after a heart attack to both predict future cardiac events and to allow the efficacy of new treatments to be assessed.

Myocardial oedema (swelling of the heart muscle) has been demonstrated using Cardiac Magnetic Resonance (CMR), to occur following a heart attack and has been suggested as a marker for future cardiac events. The optimum time to perform this scan, the method of data analysis and it's effectiveness as a predictor of future cardiac events has not been adequately assessed.

This trial will assess the amount and natural time-course of oedema in the first 10 days following a heart attack. It will also correlate the amount of oedema with the size of scar (damaged heart muscle) and left ventricular ejection fraction (heart function) at 3 months to assess if it is a predictive marker.

Questions about this trial

What is this clinical trial studying?

An observational study of Myocardial Infarction, run by Barts & The London NHS Trust 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 6 inclusion and 11 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 Feb 2013. 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?

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?

Extent and time course of myocardial oedema over the first 10 days post MI (time frame: Days 1, 3 and 10 post MI). 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 NCT00987259, which also lists 13 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 1 Feb 2013.
