This clinical trial is focused on studying heart failure, specifically a type called Heart Failure with preserved Ejection Fraction (HFpEF), which can be caused by conditions like hypertrophic cardiomyopathy or cardiac amyloidosis. The study will use a special substance called mangafodipir trisodium, which is a contrast agent used in Magnetic Resonance Imaging (MRI). This agent helps to highlight certain areas in the heart during imaging, making it easier to see how the heart is functioning.
The purpose of the study is to measure how quickly the heart takes up manganese, a component of the contrast agent, after it is administered. This will be done by using MRI to look at all parts of the left side of the heart. The study will include both healthy volunteers and patients with heart failure. Participants will receive the contrast agent through an injection, and their heart’s response will be monitored using MRI scans.
Throughout the study, researchers will compare the manganese uptake rates between healthy individuals and those with heart failure. They will also monitor for any side effects or changes in health indicators like vital signs and heart rhythms. The study aims to provide valuable insights into heart function in patients with heart failure and how it differs from healthy individuals.
