May explain exercise intolerance in HF; extends animal observations but leaves open human translation.
Does severe exercise affect peripheral vascular response differently in dogs with experimentally produced heart failure compared to control dogs?
Experimentally induced heart failure in dogs leads to an abnormal peripheral vascular response to severe exercise, characterized by blunted blood pressure elevation and intense visceral vasoconstriction.
Higgins et al. (1972) studied this question.
