WebDec 1, 2024 · The Frank–Starling law is a relationship between the filling of a ventricle and the force of contraction it develops (e.g. Holubarsch et al., 1996 ). In this way, it is also known as the heart filling–force relationship ( Katz, 2002; Saks et al., 2006 ). WebJun 22, 1984 · Nitroglycerin, when administered to patients with heart failure, causes a marked reduction in left ventricular filling pressure but often an increase in stroke volume and stroke work; based on the Frank-Starling principle, such a reduction in "preload" would be expected to result in a decrease in left ventricular end-diastolic volume and, … cane faircloth https://carlsonhamer.com
