An increase in systemic vascular resistance will cause which of the following to occur?

Question

Quizplus · Accepted Answer

Afterload is increased when aortic pressure and systemic vascular resistance are increased,by aortic valve stenosis,and by ventricular dilation.When afterload increases,there is an increase in end-systolic volume and a decrease in stroke volume.Afterload does not immediately alter preload;however,preload changes secondarily to changes in afterload.Increasing afterload reduces stroke volume and increases left ventricular end-diastolic pressure (LVEDP)(i.e. ,increases preload).This occurs because the increase in end-systolic volume is added to the venous return into the ventricle and this increases end-diastolic volume.This increase in preload activates the Frank-Starling mechanism to partially compensate for the reduction in stroke volume caused by the increase in afterload.
