老年胸痛患者颈动脉硬化与冠状动脉病变程度的相关性

目的 观察和分析老年胸痛患者颈动脉粥样硬化的特点及其与冠状动脉病变的关系.方法 对199例胸痛患者行冠状动脉造影(CAG)和颈动脉超声检查,并根据CAG结果 分为急性冠状动脉综合征(ACS)组(n=95)、稳定性心绞痛(SAP)组(n=63)和非冠心病组(n=41).比较三组颈动脉内膜中层厚度(cIMT)和颈动脉斑块积分,分析ACS相关因素以及冠状动脉病变与颈动脉病变的关系.结果 单因素非条件Logistic回归分析显示,老年ACS的发生与糖尿病、cIMT和颈动脉斑块相关(P<0.05);进一步的多因素非条件Logistic回归分析显示,cIMT和颈动脉斑块是老年ACS发病的独立危险因子(P<0.05).三组间cIMT、颈动脉斑块积分和冠状动脉造影结果 比较差异有统计学意义(P<0.05).冠状动脉积分与颈动脉斑块积分呈显著正相关(r=0.75,P=0.000).结论 颈动脉粥样硬化程度与冠状动脉病变程度相关.对老年人群进行常规颈动脉超声检查可估测冠状动脉的病变程度,有利于冠心病的早期防治.

Relationship between carotid atherosclerosis and coronary atherosclerosis in elderly patients with chest pain

Objective To explore the characteristics of carotid atherosclerosis and investigate its relationship with coronary atherosclerosis in elderly patients with chest pain.Methods One hundred and ninety-nine patients with chest pain underwent coronary angiography(CAG) and carotid ultrasonography,and were classified into acute coronary syndrome (ACS) group(n=95).stable angina pectoris(SAP) group(n=63) and non-coronary artery disease group(n=41) according to CAG findings.The carotid intima media thickness(cIMT) an...
