The effect of heart rate, preload, and afterload on the viscoelastic properties of the swine myocardium. Ann Biomed Eng. 2004;32:1211–22. : 10.1114/B:ABME.0000039355.53117.6f .Ewert D, Wheeler B, Doetkott C, Ionan C, Pantalos G, Koenig SC. The effect of heart rate, preload, and ...
However, these variables depend on preload and afterload conditions [2]. They can be difficult to interpret in unstable patients such as those in septic shock [3]. Strain echocardiography (2D-strain) is a noninvasive ultrasound imaging technique that allows for an objective and quantitative ...
Data were measured at a constant heart rate (140 beats/min) to render CO proportional to stroke dimension.At a matched increase in afterload (effective arterial elastance), L-NMMA increased preload (end-diastolic dimension) to a lesser degree (3.8%+/-1.5%, p < .05) than phenylephrine (...

Functional and Metabolic Consequences of Chronic Alterations in Preload and Afterload in the Hypertrophied and Dilated HeartChronic hypertrophic and dilative heart disease is one of the most common cardiac diseases in man (1). From the functional point of view, ventricular hypertrophy provides a basic...
