Stroke volume is maintained in the elderly person by an increase in end-diastolic volume through the Frank-Starling mechanism at every level of exercise. In younger subjects the stroke volume is ...

Diastolic heart failure is defined clinically when signs and symptoms of heart failure are present in the presence of preserved left ventricular systolic function (ejection fraction >45%).

The limited increase in left ventricular end-diastolic volume due to acute aortic regurgitation leads to a greatly increased left ventricular end-diastolic pressure and increased pulmonary artery ...

Diastolic mitral regurgitation can occur in ... prolonged left ventricular filling period increasing LV pressure toward end-diastole despite a lower left atrial pressure. The regurgitant volume ...
