Key result
Review details central and peripheral mechanisms driving exercise intolerance in HFpEF and HFrEF.
Why the study?
Factors determining exercise tolerance in heart failure patients involve central and peripheral mechanisms that differ between preserved and reduced ejection fraction.
Exercise intolerance in heart failure involves both central hemodynamic limitations and peripheral skeletal muscle dysfunction, underscoring the importance of exercise therapy alongside medical management.
Answers are grounded in this paper and cite their sources.
Supports multifactorial exercise intolerance in HF; leaves open mechanism-specific intervention trials in HFpEF versus HFrEF.

Shiraishi et al. (2022) conducted a review in Heart Failure. This review discusses the central and peripheral mechanisms of exercise intolerance in heart failure, including cardiac output, vasodilation, and skeletal muscle changes in both HFpEF and HFrEF.
