WebbHowever, we know that the neonatal myocardium is less compliant. It therefore sits on a flatter part of the Starling curve, and the same increases in preload do not result in increasing cardiac output to that which may be observed in an adult. As mentioned, neonates are heart-rate dependent for their cardiac output. Webb30 jan. 2024 · This is because the Frank-Starling curve is almost horizontal at higher preload levels in a patient whose curve is shifted downward due to systolic contractile dysfunction. However, excessive diuresis or venous vasodilation can result in an unwanted fall in stroke volume, resulting in hypotension.
