Ventricular function can be analyzed from measures of the ejecting phase of contraction (e.g. velocity and extent of wall shortening) in terms of the appropriateness of the matching between afterload and the level of inotropic state, as modulated by the preload. In the normal heart, under contr...
Both preload and afterload increases produced a biphasic response, with the highest t‐tubule densities observed at moderate loads, whereas excessively low and high loads resulted in low t‐tubule levels. To determine the baseline position of the heart on this bell‐shaped curve, mice were ...
Focuses on a study which examined the individual effects of preload, afterload and contractility on torsion using magnetic resonance imaging (MRI) with tissue tagging which permits the accurate measurement of torsion. Effect of preload and afterload on torsion; Inotropic effect on torsion; Result of ...

摘要: Alterations in ventricular preload and afterload contribute to the pathogenesis of low-output syndrome—a serious complication of acute myocardial infarction. Likewise, manipulation of preload and afterload is an effective therapeutic principle for the correction of low-output state....
The LV performance (shortening fraction), preload (LV end-diastolic dimension), afterload (wall stress), contractility, heart rate, and peak systolic blood pressure were measured. Data could be obtained during 98% of the exercise studies. The LV performance, heart rate, blood pressure, and ...
