WebSep 25, 2024 · In contrast, there was a marked increase in LVEDV and stroke volume in controls during exercise. Left ventricular end‐systolic volume did not change with exercise in either group. Given that systolic blood pressure increased considerably more in patients with HFpEF, the calculated R es was significantly greater in patients with HFpEF. WebStroke Volume Stroke volume is the amount of blood ejected per beat from left ventricle and measured in ml/beat. Stroke volume increases proportionally with exercise intensity. In untrained individuals stroke volume at rest it averages 50-70ml/beat increasing up to 110-130ml/beat beat during intense, physical activity.
