Query: Influence of some cardiovascular risk factors on the rela-tionship
  between age and blood pressure   Blood Pressure (BP) is a biological signal related to the cardiovascular
system that inevitably is affected by ageing. Moreover, it is also influenced
by the presence of cardiovascular risk factors. To evaluate how the
relationship be-tween BP and age changes with the presence of risk factors in
hypertensive and normotensive subjects, we analyzed 880 subjects with and
without smoking, obe-sity, diabetes mellitus and dyslipidemia. A regression
line fitted each BP/Age relation calculated separately for normotensive and
hypertensive subjects with and without risk factors. For each of the four
conditions the office and the 24-hour ambulatory BP monitoring (ABPM) were
considered. In subjects with and without risk factors, the slopes of the
Systolic BP/Age relation were higher in hypertensive than in normotensive
subjects in both office and ABPM conditions. Moreover, the presence of risk
factors modified the Systolic BP/Age relation in hypertensive subjects by using
either office or ABPM measurements. Finally, we confirmed that the difference
between the two modalities depends on age too.
