This study is looking at a diagnostic test called Exercise Cardiovascular Magnetic Resonance (Ex-CMR) for people with Heart Failure with Preserved Ejection Fraction (HFpEF). HFpEF is a type of heart failure where the heart pumps normally but has trouble relaxing. The study aims to see if Ex-CMR can help doctors better diagnose, understand, and predict risks for people with HFpEF who experience shortness of breath during activity. Researchers will enroll 400 participants, including people with HFpEF, people with shortness of breath not caused by heart failure, and healthy volunteers. The study will measure the number of heart failure hospitalizations and cardiac deaths at the beginning of the study to understand the current health status of participants. This is an observational study, meaning participants will not receive an experimental treatment.
