Figure 3. — Hemodynamic variables cardiac output (CO), systemic vascular resistance (SVR), and aortic distensibility (AoD) in UK Biobank stratified according to age and blood pressure (BP) group: normotensive (NTN) and isolated systolic hypertension (ISH). P values refer to significant differences in mean values of variables between age and BP groups and the interaction between age and BP (age×BP). Numbers of subjects in each group are presented in the table below the figures, numbers in brackets are for measurements of distensibility. Note that, due to the cross-sectional nature of the data, the number of individuals in the ISH group increases with age. The plots do not, therefore, provide a measure of the trend of hemodynamic variables with age.
