Figure 2. Anatomic origin of arterial properties that impact LV afterload. Although arterial load results from complex interaction between various arterial segments, in general, specific loading patterns can be attributed to anatomic sites. cfPWV, a measure of large artery wall stiffness, is also shown, although this is not a measure of LV load per se.

cfPWV = carotid-femoral pulse wave velocity; LV = left ventricle.
