Bottom Line: Pulse wave analysis (PWA) was compared.Central systolic BP and PP, augmentation pressure, augmentation index on PWA, and PWV were significantly higher or faster in the old group compared to that in the young group.However, PWV might be a better marker for old patients with HT.

ABSTRACT

Background and objectives: To investigate the impact of age on arterial stiffness and blood pressure (BP) variables in newly diagnosed untreated hypertension (HT).

Subjects and methods: A total of 144 patients with newly diagnosed untreated HT were divided into two groups: young group (age ≤50 years, n=71), and old group (age >50 years, n=73). BP variables were measured on office or 24 hours ambulatory BP monitoring (ABPM). Parameters of arterial stiffness were measured on pulse wave velocity (PWV). Pulse wave analysis (PWA) was compared.

Results: Although office BP and pulse pressure (PP) were significantly (p<0.05) higher in the young group than in the old group, BP and PP on ABPM were not significantly different. Central systolic BP and PP, augmentation pressure, augmentation index on PWA, and PWV were significantly higher or faster in the old group compared to that in the young group. Age showed significant positive correlation with both PWV and PWA variables in the young group with HT. However, age only showed significant positive correlation with PWV in the old group with HT. In the young group with HT, PWA variable showed better correlation with age than PWV.

Conclusion: Considering BP levels on ABPM, office BP is prone to be overestimated in young patients with HT. Parameters of arterial stiffness measured by PWV and PWA were more affected by age rather than by BP level in patients with HT. Therefore, PWA variable might be a more sensitive marker of arterial stiffness in young patients with HT. However, PWV might be a better marker for old patients with HT.

Figure 2: Correlation of heart-femoral (hfPWV) (A) and brachial-ankle pulse wave velocity (baPWV) (B) with age in patients with hypertension. Age showed significant positive correlation with both hfPWV and baPWV in patients with hypertension.

Mentions: Overall, age showed significant positive correlation with hfPWV (r=0.617, p<0.001) and baPWV (r=0.598, p<0.001) (Fig. 2). Age also showed significant positive correlation with central systolic BP (r=0.287, p=0.009) and PP (r=0.414, p<0.001). AP and AI also showed significant positive correlation with age (r=0.549, r=0.544, p<0.001, respectively) (Fig. 3). However, central diastolic BP did not show correlation with age (r=-0.030, p>0.05).
