Table A2.

The model input parameters, where the mean and standard deviation can vary with age (in yr)

Cardiovascular Property Mean Value Standard Deviation
Cardiac
Heart rate, beats/min Nonlinear, see text 11.2
Stroke volume, ml 72.7–0.253 × age 18.1–0.081 × age
Left ventricular ejection time, ms 282 23.3
Peak flow time, ms 79.0 11.0
Reverse flow volume, ml 0.730 0.630
Arterial
Length of proximal aorta, % of 25-yr-old 80.0 + 0.800 × age 10.7 + 0.107 × age
Diameter of larger arteries, % of 25-yr-old 90.9 + 0.365 × age 8.18 + 0.033 × age
Pulse wave velocity Nonlinear, see text Nonlinear, see text
Vascular beds
Mean arterial blood pressure, mmHg Nonlinear, see text 7.98–0.00952 × age
Peripheral vascular compliance, % of 25-yr-old 128.4–1.136 × age 35.2–0.311 × age

Coefficients are given to three significant figures. % of 25-yr-old indicates the percent change from the value(s) in the 25-yr-old baseline model.
