Exercise Training Intolerance In Heart Failure With Preserved Ejection Fraction Is Associated With Altered Chemoreflex Gain And Sympathoexcitation In Rats

Abstract

Heart failure with preserved ejection fraction (HFpEF) is characterized by cardiac dysfunction and autonomic imbalance. In HF, sympathoexcitation is strongly associated to altered chemoreflex drive. Exercise training (EX) has been demonstrated that normal
