Chf and preload
Did you know?
WebPreload. Preload is the force that stretches the cardiac muscle prior to contraction. This force is composed of the volume that fills the heart from venous return. Due to the molecular arrangement of actin and myosin in muscle, the more the incoming venous volume stretches the muscle, the further it will contract. WebThe performance of the heart is regulated by the level of myocardial contractility and the cardiac preload and afterload. These factors, previously of interest primarily to …
WebPreload can be defined as the initial stretching of the cardiac myocytes prior to contraction.

Effect on cardiac output depends on preload-responsiveness versus ability of the heart to handle increased afterload. For example, in a patient with systolic heart failure and volume overload, added preload won't help, whereas the heart may be unable to tolerate afterload – so the net effect is to ...
