Targeting Breathing Limitations to Improve Functional Outcomes in HFpEF (NCT05723679)

Targeting Breathing Limitations to Improve Functional Outcomes in Heart Failure With Preserved Ejection Fraction (HFpEF)

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿ“‹ Clinical Research Protocol Sponsor: University of Texas Southwestern Medical Center

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The overall purpose of this study is to investigate whether pulmonary limitations that increase the oxygen (O2) cost of breathing impact dyspnea on exertion (DOE) and peak exercise capacity in patients with HFpEF and obesity. As per investigator's hypothesis, obesity is likely a significant contributor to DOE and exercise intolerance in patients with HFpEF.
