Mechanisms of Exercise Intolerance in Heart Failure With Preserved Ejection Fraction

University of Texas Southwestern Medical Center·interventional·Posted Aug 28, 2019·Updated Jun 3, 2026

In Brief

A clinical study evaluating Exercise training for Heart Failure, Diastolic. Completed, enrolled 93 participants across 1 site.

Detailed Summary

The global objective of this study is to determine the mechanisms of exercise intolerance and dyspnea on exertion (DOE) in patients with HFpEF and based on this pathophysiology, test whether specific exercise training programs (whole body vs single leg) will result in improved exercise tolerance.
