Insights

Arterial stiffness, a predictor of coronary heart disease, was assessed using brachial-ankle pulse wave velocity (baPWV) and augmentation index (AI). The Framingham Risk Score correlated well with baPWV, suggesting its utility in assessing arterial stiffness.

Area of Science:

  • Cardiology
  • Vascular Medicine
  • Preventive Cardiology

Background:

  • Arterial stiffness is a significant predictor of coronary heart disease (CHD).
  • Assessing arterial stiffness aids in cardiovascular risk stratification.
  • Understanding the relationship between arterial stiffness markers and traditional risk factors is crucial for preventive strategies.

Purpose of the Study:

  • To evaluate the correlation between brachial-ankle pulse wave velocity (baPWV) and augmentation index (AI) with established risk factors for coronary heart disease (CHD).
  • To determine the applicability of the Framingham Risk Score (FRS) as an index of arterial stiffness in a healthy Japanese population.

Main Methods:

  • Cross-sectional study involving 528 healthy workers (mean age 47.9 years).
  • Measurements included brachial-ankle pulse wave velocity (baPWV) and augmentation index (AI).
  • Correlation and multivariate linear regression analyses were performed using Framingham Risk Score (FRS), body mass index, alcohol consumption, and AI P75.

Main Results:

  • The Framingham Risk Score (FRS) demonstrated a significant correlation with brachial-ankle pulse wave velocity (baPWV) (r = 0.53, p < 0.01).
  • Multivariate analysis identified FRS, body mass index, alcohol consumption, and AI P75 as significant correlates of baPWV.
  • Despite controlled blood pressure, individuals with hypertension treatment showed persistent arterial stiffness, while augmentation index (AI) was notably low.

Conclusions:

  • The Framingham Risk Score (FRS) is a valid index for assessing arterial stiffness in Japanese individuals.
  • Arterial stiffness is associated with multiple cardiovascular risk factors, including FRS, BMI, and alcohol consumption.
  • Further research is needed to understand the implications of low AI in treated hypertensive patients with residual arterial stiffness.
