PRELOAD, AFTERLOAD AND CONTRACTILITY. Preload is the initial stretching of the cardiac myocytes (muscle cells) prior to contraction.It is related to ventricular filling. Afterload is the force or load against which the heart has to contract to eject the blood. Contractility is the intrinsic strength of the cardiac muscle independent of preload, but a change in preload will affect the force of Contractility; By this model, if myocardial performance changes while preload, afterload, heart rate, and conduction velocity are all held constant, then the change in performance must be due to a change in contractility. However, changes in contractility alone generally do not occur. [citation needed] Other examples: Synonyms for contractile in Free Thesaurus.

RV systolic performance is a reflection of contractility, preload and afterload (1). In this model venous tone, heart rate and contractility of both ventricles is modulated by a negative feedback mechanism and the influence of respiration on cardiac filling and output is also taken into account. An increase in the hormone progesterone is mandatory for a successful pregnancy because it acts to inhibit smooth muscle contractibility and enable the pregnant uterus to remain stable.

Information and translations of contractility in the most comprehensive dictionary definitions resource on the web. Reduced contractility causes a reduced ventricular ejection, an increase in end systolic volume and reduced stroke volume, cardiac output, arterial blood pressure, and tissue perfusion. Again, the clinical presentation of patients with impaired contractility is similar to that of patients in hemorrhagic shock. Synonym Discussion of contract. contract, shrink, condense, compress, constrict, deflate mean to decrease in bulk or volume. contract applies to a drawing together of surfaces or particles or a reduction of area or length. shrink implies a contracting or a loss of material and stresses a falling short of original dimensions. Contractility tells us how many myosin heads are working at the end of systole; a number that goes up or down with the level of sympathetic nerve stimulation.
