This observational study is looking at how your heart's structure changes after metabolic interventions like bariatric surgery (weight loss surgery) or cardiac rehabilitation (a program to improve heart health). Researchers will use MRI (magnetic resonance imaging) scans to see these changes. The study aims to understand if these changes in your heart's tiny structures are linked to how well your heart works overall. This research could help doctors detect heart disease earlier. You might be able to join if you are over 18 and are a candidate for bariatric surgery, have heart failure, or other cardiovascular diseases. The study plans to enroll 150 participants.

Study design

This is an observational study with two groups: one for bariatric surgery candidates and one for those undergoing cardiac rehabilitation. It is a prospective longitudinal cohort design, meaning participants will be followed over time.

What's involved

If you are in the cardiac rehabilitation group, you will have an MRI at the beginning of a 12-week program. You may also choose to have an MRI of your leg.

Compensation

Not stated in the trial record.

Follow-up

Changes in your heart's microstructure will be measured from the beginning of the study and again 6-12 months later, with measurements taken at 5 years.
