Abstract.Background:The 2017 ACC/AHA blood pressure (BP) guidelines generated controversies due to the new proposed BP cut-off values defining hypertension. We aimed to assess aortic stiffness of subjects who are reclassified as stage 1 hypertensive according to the new guidelines and compare them with the subjects of “elevated BP” category. Patients and methods.Data from the “Corinthia” study, an observational, cross-sectional survey of 2,043 participants were analyzed. Subjects were classified into 4 groups: group A: systolic pressure (SBP) 120–129 and diastolic pressure (DBP) < 80 mmHg, group B: SBP 130–139 or DBP 80–89 mmHg, group B1: SBP 130–139 and DBP < 80 mmHg and group B2: SBP 130–139 and DBP 80–89 mmHg. Aortic stiffness was assessed by carotid-to-femoral pulse wave velocity (PWV). A value of PWV > 10m/s was consider indicative of asymptomatic organ damage while values of PWV exceeded the 90 % percentile for each age group were consider as abnormal. Results:Groups B, B1 and B2 have significantly increased PWV compared to group A, independently from age and other risk factors (PWV: 9.2 ± 2.8 vs 9.4 ± 2.7 vs 8.6 ± 2.5 vs 8.1 ± 2.3 m/s, p < 0.01, respectively). The prevalence of PWV > 10 m/s and abnormal PWV values in group A was significantly lower than the corresponding prevalence in randomly selected, age-matched subjects from group B (13.5 % vs 24.4 %, p = 0.027 and 5.6 % vs 14.2 %, p = 0.022, respectively). Conclusions:The reclassified subjects as stage 1 hypertensive by the new guidelines have a significantly increased aortic stiffness and greater prevalence in asymptomatic aortic damage compared to subjects with elevated BP. This finding may indirectly explain the increased cardiovascular risk of this group. |
