<prompt> If the ejection fraction increases, there will be a decrease inCardiac outputEnd-systolic volumeHea ratePulse pressure  <response>: An increase in ejection fraction means that a higher fraction of the end-diastolic volume is ejected in the stroke volume e.g., because of the administration of a positive inotropic agent. When this situation occurs, the volume remaining in the ventricle after systole, the end-systolic volume, will be reduced. Cardiac output, pulse pressure, stroke volume, and systolic pressure will be increased.
