Why the study?
Does heat acclimation alter cardiac performance in isolated rat hearts?
Does heat acclimation alter cardiac performance in isolated rat hearts?
Heat acclimation in rats alters intrinsic cardiac properties, increasing compliance and reducing chamber stiffness while impairing contractility restitution at high heart rates.
No takes yet. Share an insight, caveat, or question.
Heat acclimation alters rat heart mechanics; hypothesis-generating for human translation and should not yet change practice.
Horowitz et al. (1986) studied this question.
