Atrial Fibrillation Trial, Recruiting
Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
ICM group (with implantable cardiac monitor):
- Adults aged 18 or older
- Able and willing to provide written consent to participate
- Diagnosed with a type 1 heart attack (as defined by current international medical guidelines)
- Coronary arteries that are not significantly blocked (less than 50% narrowing) as seen on an imaging procedure that looks at the heart's blood vessels
- No obvious specific cause identified for the heart attack at the time of the acute event
- A specific pattern of scarring seen on a cardiac MRI scan that suggests the heart attack was caused by reduced blood flow
- No clear underlying cause found for the heart attack, meaning there is a higher likelihood that an irregular heart rhythm called atrial fibrillation may be responsible
Non-ICM group (without implantable cardiac monitor):
- Adults aged 18 or older
- Able and willing to provide written consent to participate
- Diagnosed with a type 1 heart attack (as defined by current international medical guidelines)
- Coronary arteries that are not significantly blocked (less than 50% narrowing) as seen on an imaging procedure that looks at the heart's blood vessels
- No obvious specific cause identified for the heart attack at the time of the acute event
- A specific pattern of scarring seen on a cardiac MRI scan that suggests the heart attack was caused by reduced blood flow
Who may not be able to join:
ICM group:
- People already known to have an irregular heart rhythm called atrial fibrillation or atrial flutter
- People who have previously had a procedure to treat atrial fibrillation or atrial flutter
- People with a known diagnosis of coronary artery disease
- People who have had a previous heart attack
- People who have previously had a procedure to open blocked heart arteries (such as a stent)
- People who have previously had open-heart bypass surgery
- People who are unable to have a cardiac MRI scan — for example, because they have a non-MRI-compatible implanted heart device, or because their kidneys are not functioning well enough (confirm with trial site)
- People for whom implanting a small cardiac monitoring device is not medically appropriate (confirm with trial site)
- People in whom a clear cause for the heart attack is found before the monitoring device is implanted
Non-ICM group:
- People with a known diagnosis of coronary artery disease
- People who have had a previous heart attack
- People who have previously had a procedure to open blocked heart arteries (such as a stent)
- People who have previously had open-heart bypass surgery
- People who are unable to have a cardiac MRI scan — for example, because they have a non-MRI-compatible implanted heart device, or because their kidneys are not functioning well enough (confirm with trial site)
