目的:研究臂踝脉搏波传导速度(baPWV)在冠心病患者中的诊断价值,并观察臂踝脉搏波传导速度改变(baPWV%)对冠状动脉狭窄程度评估的作用,为临床诊疗提供依据。方法:选取2013年7月-2015年9月我院预行冠状动脉造影患者463例,根据冠状动脉造影情况将入选者分为冠心病组(n=262)和非冠心病组(n=201),冠心病组根据SYNTAX评分将患者分为轻、中、重度组,所有入选者均行baPWV和baPWV%检查,并分析其与SYNTAX评分的相关性。结果:冠心病组baPWV和baPWV%均显著高于非冠心病组,比较差异具有统计学意义(P<0.05);重度组baPWV和baPWV%显著高于中度组和轻度组,中度组baPWV和baPWV%显著高于轻度组,比较差异具有统计学意义(P<0.05);相关性分析显示:baPWV%与SYNTAX评分呈正相关关系(P<0.05)。结论:baPWV和baPWV%对冠心病具有一定诊断价值,且baPWV%与SYNTAX评分呈正相关关系。
Objective: To investigate the diagnostic value of brachial-ankle pulse wave velocity (baPWV) in patients with coronary heart disease (CHD) and to observe the effect of baPWV% on the evaluation of coronary artery stenosis and to provide evidence for clinical diagnosis and treatment. Methods: 463 patients undergoing coronary angiography in our hospital from July 2013 to September 2015 were enrolled. Patients were divided into coronary heart disease group (n = 262) and non-coronary heart disease group (n = 201) according to coronary angiography ). According to the SYNTAX score, patients in the CHD group were divided into mild, moderate and severe groups. All patients were examined for baPWV and baPWV%, and their association with SYNTAX score was analyzed. Results: The baPWV and baPWV% of coronary heart disease group were significantly higher than those of non-coronary heart disease group, the difference was statistically significant (P <0.05); baPWV and baPWV% of severe group was significantly higher than that of moderate and mild group baPWV and baPWV% were significantly higher than those in mild group (P <0.05). Correlation analysis showed that there was a positive correlation between baPWV% and SYNTAX score (P <0.05). Conclusion: baPWV and baPWV% have certain diagnostic value for coronary heart disease, and baPWV% and SYNTAX score have a positive correlation.
