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.
Inclusion Criteria: 1. Informed consent obtained 2. Three groups will be enrolled: 1. HFpEF (cardiologist-adjudicated diagnosis as verified by PI, EF≥50%) 2. Non-cardiac dyspnea (patients have dyspnea but were found on invasive exercise testing not to have HFpEF). 3. Healthy volunteers with no history of dyspnea or effort intolerance. Exclusion Criteria: 1. Contraindication for low-field CMR, as indicated in MRI safety screening checklist (Research Document #1) 2. Patient inability or unwillingness to undergo Ex-CMR 3. Cardiac implants, mechanical or biological valve, causing arti…
