【摘要】目的 评价踝臂脉搏波传导速度(baPWV)与冠心病不同程度心功能不全的相关性.方法 连续入院253例明确诊断冠状动脉粥样硬化性心脏病的患者,按纽约心脏病学协会标准(NYHA)进行心功能分级,所有患者采用无创动脉硬化自动测定仪测量baPWV,同时测定脑钠肽(BNP),左室射血分数(LVEF),左室舒张末容量(LVEDV),左室收缩末容量(LVESV),并进行相关性分析.结果 baPWV与BNP(r=0.394,P<0.001)、NYHA分级(r=0.444,P<0.001)、LVEDV (r=-0.130,P<0.05)之间具有显著相关性,但与LVEF、LVESV之间无显著相关性.ROC曲线下面积表明:当baPWV>1717 cm/s时,诊断心功能不全的敏感性为72.9%,特异性为61.8%;左侧踝臂脉搏波传导速度(LbaPWV)≥1900 cm/s时,其对应的敏感性是61.5%,特异性是81.9%.结论 baPWV与冠心病患者NYHA分级之间具有显著相关性,可作为评价心功能的一个指标.%Objective To investigate the relationship between brachial-ankle pulse wave velocity (baPWV)and different stage of cardiac dysfunction.Methods 253 consecutive patients with coronary atherosclerotic heart disease were enrolled from August 2006 to February 2007.Patients were grouped according to the functional classification of New York Heart Association(NYHA).The baPWV was measured non-invasively with a VP1000
