Abstract

BACKGROUND/AIMS
Although brachial-ankle pulse wave velocity (baPWV) has been validated as a novel method to predict the cardiovascular risk in general population, the relevance of baPWV to the traditional risk scores has not been clearly revealed. This study investigated the relationship between baPWV and four different cardiovascular risk-predicting scores in men and women.
METHODS
A total of 539 subjects (58.1 ± 12.2 years, 50.1% men) without cardiovascular disease (CVD) who underwent health examinations including baPWV measurement were retrospectively analyzed. Four cardiovascular risk scores (Framingham risk score [FRS; 1998], Adult Treatment Panel [ATP] III revised FRS [2002], generalized FRS [2008], and American College of Cardiology/American Heart Association [ACC/AHA] CVD risk [2013]) were calculated in each subject.
RESULTS
In a total population, baPWV was moderately correlated with four cardiovascular risk scores (r = 0.577 for FRS; r = 0.594 for ATP III revised FRS; r = 0.589 for generalized FRS; r = 0.571 for ACC/AHA CVD risk; p < 0.001 for each). These correlations were stronger in women than in men (r = 0.649 vs. 0.451 for FRS; r = 0.719 vs. 0.411 for ATP III revised FRS; r = 0.735 vs. 0.540 for generalized FRS; r = 0.699 vs. 0.552 for ACC/AHA CVD risk; p for gender difference ≤ 0.005 for each).
CONCLUSIONS
In middle-aged and elderly Koreans without CVD, baPWV was identified as having a moderately positive correlation with four different risk scores. The correlation was stronger in women than in men, implying the better performance of baPWV in women for predicting cardiovascular risk of healthy population.
