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, … WebThe effect of preload on SV is described by the Frank–Starling mechanism (Fig. 5.1) eponymously attributed to the German-born doctor and physiologist, Otto Frank (1865–1944), and later work by the English physiologist, Ernest Starling (1866–1927).This is described as the “principal mechanism by which the heart adapts to changing inflow of …
