Clinical Trial Summary

The investigators are studying whether metabolic abnormalities in cardiac and skeletal muscle in patients with heart failure with preserved ejection fraction (HFpEF) are associated with debilitating exercise intolerance.


Clinical Trial Description

This research is being done to better understand why patients with heart failure have difficulty exercising and performing some activities of daily living. Heart muscle and skeletal muscle (in the legs and arms) depend on normal metabolism (the conversion of foods to chemical fuel) to function properly. Investigators will measure metabolites in the heart and leg muscles, including the levels of high energy phosphates and lipids (fats) using magnetic resonance (MR) techniques. High-energy phosphates serve as a source of energy, which is used by the heart and skeletal muscle for contraction. Magnetic resonance uses magnetic fields to measure the levels of these substances. ;
