Cardiac MRI study (MyoFit46)

We are inviting participants from the MRC National Survey of Health and Development to join a new cardiac sub-study called MyoFit46.

What is the purpose of this study?

A huge number of people are now surviving to older age but there is still a lack of knowledge about how heart function changes as we get older. We hope to determine how environmental factors and life-course events contribute to mortality, frailty, disability and loss of independence in advanced age. Through advanced and safe imaging techniques, we will be able to investigate the hearts of study members of the MRC NSHD and vastly improve our understanding of cardiac ageing.

What does the study involve?

If you choose to take part then we will invite you to have a heart MRI scan. This will allow us to study your heart structure and function, both at rest and under stress conditions. We will contact you before the scan to perform a short questionnaire to check that you are safe to go into the scanner.

On the day of the scan you will be asked to lie on your back for around 5 minutes whilst we record an ECG of your heart rhythm.

We will then invite you to lie on your back inside the heart MRI scanner for about 40 minutes while a radiographer or doctor operates the scanner from behind a window. We will use a small plastic cannula to administer a simple ‘dye’ and a small amount of medication to simulate physical exercise during the test.

You will be provided with an information booklet prior to consenting to the study and you can get in touch with the study team at any time if you have any queries.
