Abstract

Objective:

The aim of this study is to evaluate the central blood pressure values in a healthy Mexican sample.

Design and method:

We included 617 healthy individuals without risks factors of 1047 gathered in our centre. Ages ranged from 18 to 78 years. We used the HEM9000AI non-invasive tonometric device on radial artery to obtain central and peripheral parameters in the same assessment. Due to important age and sex interaction, we divided the groups by decades and gender. We report medians, 95% confidence intervals (CI),Pearson's correlation coefficient and Student's T test.

Results:

The average height, weight and body mass index (BMI) in males were 175 cm; 77.3 kg and 25.1 and for women was 161.6 cm, 63.5 kg and 24.2, respectively. cSBP values in females and males were the following: < 30 years (94, 96 mmHg); 30–39 years (104, 107 mmHg); 40–49 years (107, 112 mmHg); 50–59 years (114, 115 mmHg); > 60 years (113, 117 mmHg). Similarly to cSBP, central pulse pressure (cPP) values (not shown) had a constant increase correlating with age (r = 0.559, p < 0.001). We found similar mean cSBP values between women and men 103.32 vs 103.36 mmHg respectively (p = 0.973). (Table 1)

Conclusions:

Assessing reference values in healthy population sample is the first step to establishing normal values for a particular population. Central hemodynamic values have been assessed mostly in European and Asian populations. Due to the high prevalence of cardiovascular mortality in Mexico, it is very important to stablish these cut-off values. We need a larger sample to generalize this to the general Mexican population.
