PRELOAD, AFTERLOAD, AND CARDIAC OUTPUT IN INFANT LAMBS DURING UNILATERAL POSITIVE END EXPIRATORY PRESSURE (PEEP).An abstract is unavailable. This article is available as a PDF only.doi:10.1097/00003246-198203000-00020Fuhrman, Bradley P.Everitt, John...
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...

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 (...
The hearts were injected with cardiac and vascular progenitor cells while supported in an organic reactor that simulated the preload and afterload of cardiac physiology. The result after 8 days of incubation was the detection of macroscopic contractions and overall pump strength e...

The booster pump, also called contractile function, quantifies the amount of blood being pumped into the LV during LA contraction. It is modulated by the LV compliance, LA afterload, LA preload, and intrinsic LA contractility. In late ventricular diastole, the LA pumps all the remaining blood...
It has been nearly 15 years since the discovery of human-induced pluripotent stem cells (iPSCs). During this time, differentiation methods to targeted cells have dramatically improved, and many types of cells in the human body can be currently generated at high efficiency. In the cardiovascular ...
From these results we have concluded that the cardiac output response to physical reduction of preload and afterload depends on both the type of heart disease and the height of the initial ventricular filling pressures. The small increases in cardiac output that occurred in patients with severely ...
PreloadAfterloadAngiotensinProteins are folded in the endoplasmic reticulum (ER). ER stress initially leads to compensatory upregulation of ER chaperones and later to apoptosis, but the contribution of biomechanical load vs. neurohumoral stress to myocardial ER stress is unknown. We show that the ER...
