About this trial
The purpose of this study is to internally validate low-field Ex-CMR as a noninvasive tool for diagnosing, phenotyping, and risk stratifying HFpEF in patients with exertional dyspnea.
Eligibility criteria
Qualifiers
Informed consent obtained
HFpEF (cardiologist-adjudicated diagnosis as verified by PI, EF≥50%)
Non-cardiac dyspnea (patients have dyspnea but were found on invasive exercise testing not to have HFpEF).
Healthy volunteers with no history of dyspnea or effort intolerance.
Disqualifiers
Contraindication for low-field CMR, as indicated in MRI safety screening checklist (Research Document #1)
Patient inability or unwillingness to undergo Ex-CMR
Cardiac implants, mechanical or biological valve, causing artifacts that compromise the quality of data
Hospitalization for heart failure in the preceding 30 days.
