Exercise Cardiovascular Magnetic Resonance / Heart Failure With Preserved Ejection Fraction · Observational Study
ClinicalTrials.gov · August 20, 2026
Early or partial results. Treat as a signal, not a conclusion.
This is an active observational registry study at Mayo Clinic designed to validate low-field exercise cardiovascular magnetic resonance (Ex-CMR) as a diagnostic and risk-stratification tool in heart failure with preserved ejection fraction. No efficacy or safety results are yet reported in this registry record; the study remains in recruiting phase.
Observational. Heart Failure With Preserved Ejection Fraction; age from 18 Years; to 80 Years; accepts healthy volunteers. Intervention: HFpEF (Heart Failure with Preserved Ejection Fraction); Non-cardiac dyspnea; Healthy Volunteers. n = 400. 1 site: United States.

Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians should not yet base decisions on this study; it is in active recruitment and has not reported efficacy or safety outcomes. When results are published, the diagnostic accuracy and prognostic value of low-field Ex-CMR in HFpEF may inform non-invasive assessment strategies.
This is an active observational registry study with no reported results; it describes planned enrollment and outcome measures without efficacy data.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no key findings. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07401771). This is a study registration, not published results. Lead sponsor: Mayo Clinic. Recruitment status: RECRUITING. Study type: OBSERVATIONAL. Enrollment: 400 participants (ESTIMATED). Conditions: Heart Failure With Preserved Ejection Fraction. Interventions: DIAGNOSTIC_TEST: Exercise Cardiovascular Magnetic Resonance. Primary outcome measures: Number of heart failure hospitalizations , Baseline; Number of cardiac deaths , Baseline. Brief summary: 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.
