Abstract

Aims: The purpose of the study was to investigate the agreement between carotid-femoral pulse wave velocity (cfPWV) and augmentation index adjusted at heart rate 75 bpm (AI@75) and to examine the relationship of AI@75 and cfPVW to demographic factors and blood pressures (BPs) in Korean Americans.

Methods: This study was a secondary analysis of a previous data setfrom 102 Korean Americans. AI@75 and cfPWV were measured using the SphygmoCor equipment. Age, gender, height, body weight and brachial BPs were included in the analysis.

Result and conclusion: cfPWV and AI@7S showed a good agreement. DBP was independently associated with both cfPWV (p=.022) and AI@75 (p<.001). Although PP is considered a surrogate measure of arterial stiffness, it was related to neither cfPWV nor AI@75 in our healthy middle-aged Korean Ameri- cans. Unlike cfPWV, AI@75 should be measured and analyzed carefully considering height since height was independently related to AI@75 (p<.001).

增强指数与脉搏波速度——两个指标的一致性及其与血压的关系。

目的:本研究的目的是调查颈股脉波速度(cfPWV)和心率75bpm调整后的增强指数(AI@75)之间的一致性，并研究AI@75和cfPVW与韩裔美国人人口统计学因素和血压(bp)的关系。方法:本研究是对102名韩裔美国人先前数据集的二次分析。使用sphygmoor设备测量AI@75和cfPWV。年龄、性别、身高、体重和肱bp均纳入分析。结果与结论:cfPWV与AI@7S具有较好的一致性。DBP与cfPWV (p= 0.022)和AI@75 (p= 0.022)独立相关
