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.
Reversed Circadian Variation in Variant Angina
민희석,구본권,김민경,임학령,김효수 대한심장학회 2008 Korean Circulation Journal Vol.38 No.1
It is known that there is a marked variation in the frequency of variant angina attacks according to the circadian rhythm. The attack frequency is usually highest in the early morning and lowest in the afternoon. We describe here a middle-aged woman with variant angina whose chest pain occurred only during daytime. Because of her job, she sleeps from noon to 6 pm, and she experienced chest pain only during 2 to 3 pm. These findings suggest that the alterations to the sleep and wake cycle can affect the circadian variation of variant angina. (Korean Circ J 2008;38:66-68)
