Figure 1
Schematics of changes in P-V (Pressure-Volume) loops of the LV (left ventricle) and in SV (stroke volume) and EF (ejection fraction). The upper panels indicate the effects of increases in preload (A) and afterload (B) shown in red vs. control P-V curves in black. Data to support such changes were published in J. Physiol. 48: 465, 1914 by Patterson, Piper, and Starling. The lower panels indicate the effects of cardiac remodeling in heart failure with hypertrophic cardiomyopathy in (C) and dilated cardiomyopathy in (D) with reduced and increased EDVs (end-diastolic volumes) respectively.
