Insights
Initial hypertension impairs arterial elasticity early on. This study used two methods to detect these changes in hypertensive patients compared to healthy individuals.
Area of Science:
- Cardiovascular physiology
- Vascular biomechanics
- Hypertension research
Context:
- Arterial stiffness is a key indicator of cardiovascular health.
- Early detection of arterial changes in hypertension is crucial for timely intervention.
- Wave intensity (WI) and brachial-ankle pulse wave velocity (baPWV) are non-invasive methods to assess arterial properties.
Purpose:
- To investigate early alterations in arterial elasticity in patients with initial hypertension.
- To compare the efficacy of two distinct methods, wave intensity technique and baPWV, in detecting these changes.
- To identify specific parameters indicative of impaired arterial function in early hypertension.
Summary:
- Hypertensive patients exhibited significantly higher bilateral baPWV compared to the normal group.
- Key arterial elasticity parameters, including stiffness parameter (β) and pressure-strain elastic modulus (Ep), were significantly altered in the hypertension group.
- Reduced arterial compliance (AC) and altered wave parameters (W(1), W(2)) were observed in individuals with initial hypertension, indicating impaired elasticity.
Impact:
- This study highlights that arterial elasticity changes can be detected in the early stages of hypertension.
- The findings suggest that non-invasive methods like WI and baPWV can effectively identify early vascular dysfunction.
- Understanding these early changes can lead to improved diagnostic strategies and therapeutic interventions for hypertension, potentially reducing long-term cardiovascular risk.
Objective:
To explore the early changes of arterial elasticity in initial hypertension through two different methods.
Methods:
A total of 76 hypertensive patients (Grade 1-2, n = 32) were assigned into hypertension group while the age and gender-matched healthy population was selected as normal group (n = 44). All of them were monitored for baPWV in right carotid artery by wave intensity technique. The parameters of two methods were compared between two groups.
Results:
Higher bi-lateral baPWV were found in the hypertension group (right: (1472 ± 198) m/s vs (1353 ± 233) m/s), (left: (1465 ± 198) m/s vs (1353 ± 241) m/s) (P < 0.05). Compared with the normal group, Patients in the hypertension group had statistically higher W(1) ((9.8 ± 3.8)×10(3) mm Hg×m×s(-3) vs (7.4 ± 2.4)×10(3)) mm Hg×m×s(-3), W(2) ((2.8 ± 1.1)×10(3) mm Hg×m×s(-3) vs (2.0 ± 1.0)×10(3) mm Hg×m×s(-3)), stiffness parameter (β) ((6.9 ± 2.6) vs (5.1 ± 1.3)), pressure-strain elastic modulus (Ep) ((99 ± 39) kPa vs (57 ± 17) kPa), one-point wave velocity (PWVβ) ((6.0 ± 1.1) m/s vs (4.6 ± 0.6) m/s), PWVWI ((6.2 ± 1.4) m/s vs (4.4 ± 1.0) m/s) (P < 0.01). R-W(1) ((100 ± 14) ms vs (103 ± 13) ms), (W(1)-W(2)) ((261 ± 20) ms vs (274 ± 15) ms) and arterial compliance (AC) ((0.8 ± 0.4) mm(2)/kPa vs (1.1 ± 0.3) mm(2)/kPa) in the hypertension group were statistically lower than those of the normal group (P < 0.05).
Conclusion:
The initial hypertensive patients may have impaired arterial elasticity during an early stage.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
