冠心病患者肱-踝脉搏波传导速度与颈动脉内中膜厚度相关性的研究

目的 通过研究冠心病患者肱-踝脉搏波传导速度(baPWV)与颈动脉内中膜厚度(cIMT)的变化及相关性,探讨动脉硬化和动脉粥样硬化之间的相关性.方法 本研究入选102例在本院行冠脉造影的患者,按冠脉造影的结果 分为对照组和冠心病组,冠心病组根据冠脉病变程度进一步分为单支、双支、多支病变组.所有入选者在冠脉造影前用日本欧姆龙科林一起同步记录两侧baPWV,用超声检测cIMT.结果 冠心病组baPWV、cIMT明显高于对照组,差异有统计学意义(P<0.05);冠状动脉病变程度分析中baPWV、cIMT随着冠脉病变程度加重均有增高趋势,其中多支病变、双支病变组baPWV和cIMT均高于单支病变组、对照组,单支病变组baPWV明显高于对照组,差异有统计学意义(P<0.05).将选入的患者baPWV和cIMT做直线相关分析,结果 呈正相关(r=0.451,P<0.001).在控制了吸烟、高血压病史、糖尿病史等多种动脉粥样硬化危险因素后,这种相关性仍然存在(r-0.391,P<0.01).结论 baPWV和cIMT密切相关,在一定程度上说明动脉硬化与动脉粥样硬化可能存在相关性.

Relationship between brachial-ankle pulse wave velocity and carotid intima media thickness in patients with coronary heart disease

Objective By detecting brachial-ankle pulse wave velocity and carotid intima media thickness in the patients with coronary heart disease,to investigate the relationship between coronary stiffness and coronary artherosclerosis.Methods One hundred and two patients who were performed by coronary angiography(CAG) were divided into two groups according to the result of CAG:coronary heart disease group and control group.Coronary heart disease group was divided into single-vessel group,dual-vessel group and multip...
