In the presence of diastolic dysfunction, left ventricular contractility may be preserved; however, cardiac output still falls because of inadequate left ventricular filling.
The reason for this is unclear but indicates that the SV in HF patients is more dependent on LV contractility (the 'limiting' factor), whereas the SV in normal and septic subjects is likely to be dependent on other factors such as HR, preload, afterload, increased LV wall thickness and the use of vasoactive medication.
