In an effort to combat a reduction in stroke volume, the heart utilizes 3 compensatory mechanisms to increase ejection fraction and perfusion: the adaptive mechanisms. Frank-Starling Principle: increased preload (EDV) causes an increased stretching and thus reflex contraction of sarcomeres, enhancing cardiac contractility
