B2AD-Risk AFDAS Evolution of Burden of AF
Every year, millions of people worldwide have a type of stroke often caused by an irregular heartbeat called atrial fibrillation (AF), which can lead to severe problems. This study focuses on patients who have had a stroke and were then newly diagnosed with AF. We want to understand how their AF changes over time, including how often it occurs and how serious it is. Researchers will also look at heart health markers and new risk factors like high blood pressure. By following participants for up to two years, this study aims to provide important information that could lead to better ways to treat and prevent strokes in people with AF.
At a glance
What is this study about?
Imagine your heart usually beats with a steady rhythm, like a drum. Sometimes, it can beat irregularly, which is called atrial fibrillation (AF). This irregular heartbeat can cause blood clots to form, which can then travel to the brain and cause a stroke. Millions of people around the world have strokes every year, and AF is a big reason why many strokes happen. This study is all about understanding what happens to AF after someone has already had a stroke.
The main goal is to monitor people who have had a stroke and then found out they have AF. We want to see how this AF changes over time – does it become more frequent, or more severe? We'll also be looking at things like blood tests that show heart health, how the heart's pumping chambers are working, and if new health problems like high blood pressure develop. This information will help doctors understand more about how AF progresses in these patients. By learning more, we hope to find better ways to treat AF and prevent future strokes.
Participants will be followed for up to two years. The researchers hope to learn if the AF tends to get worse over time, if new health issues appear, or if there are changes in heart-related markers. This research is really important because it could lead to new ways to help patients reduce their risk of another stroke and improve their overall heart health.
Key takeaways
- This study focuses on people who have had a stroke and also have an irregular heartbeat called atrial fibrillation (AF).
- It aims to understand how AF changes over time after a stroke.
- Information from this study could lead to better stroke prevention and treatment.
- Participants will be monitored for up to two years.
- Current medical care for AF and stroke will continue during the study.
Who may be eligible?
This study is looking for adults who have recently had a type of stroke called an ischemic stroke. This is a stroke caused by a blood clot. You might be eligible if you also have atrial fibrillation (AF), which is an irregular heartbeat. This AF could have been known before your stroke, or it might have been discovered when you were admitted to the hospital, or during heart monitoring of your heart rhythm for up to 14 days after your stroke.
There are some conditions that would mean you can't join the study. These include if you have a different type of AF that is always there (called permanent or persistent AF), or if you are allergic to certain dyes used in medical tests. Also, if you're not comfortable agreeing to take part, then this study wouldn't be for you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you an adult aged 18 or over?
- Have you recently had a type of stroke caused by a blood clot?
- Do you have atrial fibrillation (AF) that was known before your stroke or discovered after your stroke (either by ECG or monitoring for less than 14 days)?
- Do you NOT have a permanent or persistent form of AF?
- Are you NOT allergic to common medical imaging dyes?
- Are you willing and able to give your consent to participate?
What does participation involve?
If you join this study, you will be followed for up to 24 months (two years). During this time, you'll have regular check-ups where doctors will assess your health. This will involve monitoring your heart's activity to see how your atrial fibrillation (AF) changes, checking for new health conditions like high blood pressure, and looking at blood markers related to heart health. You won't be given any new medication specifically for the study, but your doctors will continue to manage your existing treatments. The study aims to gather information without making changes to your current treatment plan.

Common questions
What is atrial fibrillation (AF)?
AF is when your heart beats with an irregular rhythm, which can sometimes lead to blood clots and strokes.
Why is this study important?
It helps us understand how AF changes after a stroke, which could lead to better ways to prevent future strokes.
Will I receive new treatment in this study?
No, the study will observe your AF and health, but you'll continue with your usual medical care.
How long does the study last?
You could be involved in the study for up to two years.
What is an 'Implantable Loop Recorder'?
This is a small device placed under the skin to continuously monitor your heart's electrical activity over a long period.
