In younger subjects the stroke volume is increased by a progressive decrease in end-systolic volume and little change in end-diastolic volume (Figure 3). The increased plasma catecholamines can ...

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%).

Elite athletes showed increased LV end-diastolic diameter, end-diastolic volume and stroke volume, whereas circumferential end-systolic stress was higher in patients with hypertension. LA diameter and ...
