(afterload I) and 15 to 20 mm Hg (afterload II) with graded aortic occlusion during inotropic stimulation with dobutamine (2.5 and 5 μg/kg body weight per min intravenously), with simultaneous 5-μg/kg per min dobutamine infusion and afterload II and during 2.5% halothane (negative ...
speed,LVADoutput is dependent on preload and sensitive to afterload. Preload is a function of LV filling, which is primarily determined by volume status/filling pressure and right heart function. It is axiomatic that the right heart must generate adequate output to maintain LV filling and LVAD ...
Using conventional echocardiography, left ventricular ejection fraction (LV EF) and fractional shortening are routinely used [1]. 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]. ...

Conclusion: When preload and afterload are unaltered after the race, because of the adoption of a unique assessment posture, LV systolic function is not depressed. A depression in LV diastolic function persists which is not explained by an increase in heart rate after the race....
The LV DP reflects the overall pressure output, which is determined by the preload, afterload and contractility. Myocardial contractility measures the intrinsic ability of myocardial fibers to generate force, which is load-independent. The overall finding of Conclusion In this study, we found that ...
