Patient information sheet  for children up to 12 years old
What’s it about? 
We want to ask you to take part in a study of your heart and your blood. We want to know if your blood can tell us how healthy your heart is.
You can choose if you want to be in this study or not.

What will happen if I agree to take part in the study? 
We take a few drops of blood from your arm and we make a video of your heart:

When and how long? 
You visit the hospital 1x, and this visit lasts 45 minutes.

What are the pluses and minuses? 
•	You do not gain anything from this study.  Taking part helps doctors to understand the heart better, so they can cure more children who are ill. 
•	When your blood is taken it may hurt a little bit. A scan of the heart does not hurt. 
•	If you do not take part in the study, it makes no difference to your health. You will get the standard treatment. 
Important to know: 
•	You don’t have to be in the study
•	Even if you have started the study, you can always change your mind and you don’t have say why
•	You can always ask questions. 

If you have questions
If you have questions, you can ask your parents. Or you can ask the doctor John Example. 
You can mail the doctor at: askthedoctor@ziekenhuis.nl.
