Starling’s law states that: the more the heart chambers fill, the stronger the ventricular contraction, and therefore the greater the stroke volume.Therefore, a rise in central venous pressure will result in an increased stroke volume automatically. This is because, as the heart chamber fills and stretches, it …
WebbDiastolic dysfunction has been documented in many but not all studies, although the interpretation of some data is limited due to higher blood pressure in the PHPT group. 62,64,67,77 Two recent studies in mild PHPT in which relevant cardiovascular risk factors were known showed no increase in diastolic function in PHPT. 68,78 In contrast, a third … WebbFrank-Starling curves show how changes in ventricular preload lead to changes in stroke volume. ... Diastolic dysfunction is best diagnosed by specific cardiac catheterization measures of pressure-volume relationships, but this is impractical in most situations.

Webb(LV) Starling curves to elaborate a framework for anticipating and treating LV distension. A previously developed and validated model of the cardiovascular system was used to generate pressure–volume (PV) loops and Starling curves while holding mean arterial pressure (mABP) constant at a range of values either by adjusting systemic resistance …
