preload

 [pre´lōd]
the volume of blood in the ventricle at the end of diastole.

pre·load

(prē'lōd),
1. The load to which a muscle is subjected before shortening.
2. Synonym(s): ventricular preload

preload

/pre·load/ (pre´lōd) the mechanical state of the heart at the end of diastole, the magnitude of the maximal (end-diastolic) ventricular volume or the end-diastolic pressure stretching the ventricles.

preload

[prē′lōd]
Etymology: L, prae + AS, lad
the stretch of ventricular muscle fibers at end diastole. It is reflected by the ventricular pressure and volume at that part of the cardiac cycle. Cardiac output increases with preload. Also called preload filling pressure.

preload

Cardiology The amount of hemodynamic pressure upstream from the heart, which is ↑ in heart failure due to mitral or aortic valve regurgitation. Cf Afterload.
