Researchers are testing a new way to diagnose and understand heart failure with preserved ejection fraction (HFpEF)—a condition where your heart pumps blood normally but has trouble relaxing between beats, causing shortness of breath during activity. The study uses a special type of heart imaging scan (called low-field CMR) that takes pictures while you exercise, which may help doctors diagnose this condition more accurately than current methods.
Many people feel short of breath during activity, but doctors struggle to figure out if it's caused by this specific type of heart failure or by something else. This new imaging test during exercise could help doctors diagnose the condition earlier and identify who is at highest risk, leading to better treatment and care.

You would visit Mayo Clinic to undergo a special heart imaging scan called low-field CMR (cardiovascular magnetic resonance), which takes detailed pictures of your heart while you exercise on a treadmill or stationary bike inside the imaging machine. The scan is noninvasive—no needles or surgery—and helps doctors see how your heart functions during activity. The study is still recruiting participants, so the exact number and timing of visits would be discussed with the research team.
