Improving breathing and exercise ability in heart failure patients

Official title: Targeting breathing limitations to improve functional outcomes in HFpEF

Funded at Ut Southwestern Medical Center · NIH-10871825 · Data updated 2026-11-12

This study is looking into why people with heart failure and preserved ejection fraction (HFpEF) have trouble breathing and struggle with exercise, especially how being overweight might make these issues worse, with the goal of finding better ways to help improve their breathing and overall quality of life.

Who could benefit from this research

Could help

Ideal candidates for this research are adults with heart failure and preserved ejection fraction, particularly those who are also experiencing obesity-related breathing difficulties.

Less likely to help

Patients without heart failure or those who do not have obesity-related symptoms may not benefit from this research.

What this research studies

This research investigates the causes of breathing difficulties and exercise intolerance in patients with heart failure and preserved ejection fraction (HFpEF), particularly focusing on how obesity may exacerbate these symptoms. The study aims to understand the physiological mechanisms behind dyspnea on exertion (DOE) and how obesity affects breathing mechanics during physical activity. By identifying these factors, the research seeks to develop new therapeutic strategies to alleviate these debilitating symptoms and improve patients' quality of life.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that significantly improve breathing and exercise capacity for patients with heart failure.

How similar studies have gone: Previous research has indicated that addressing obesity-related breathing issues can improve outcomes in similar patient populations, suggesting a promising avenue for this investigation.
