Figure 2 Effects of age on vascular stiffening and load. A shows pulse pressure versus age, and B shows arterial elastance, a measure of total (mean and pulsatile) arterial load, versus age. Both parameters significantly increased with age. Open circles = group 1 subjects with no demonstrable cardiovascular disease. Open triangles = those with coronary artery disease and no infarction or a history of systolic hypertension. Solid lines = linear regression for combined data.
