颈动脉粥样硬化与冠心病的相关性

A study of correlation between carotid atherosclerosis and coronary atherosclerosis heart disease

目的 :研究颈动脉粥样硬化 (CAS)与冠心病 (CHD)的相关性。方法 :非脑血管病患者 5 2例分为对照组 (10例 ) ,心绞痛组 (16例 ) ,心肌梗死组 (2 6例 )。冠心病依据心电图 ,运动 -静息 99m Tc- MIBI心肌显像 (SPECT)诊断 ;颈动脉粥样硬化用多普勒超声诊断仪检测。结果 :对照组颈动脉超声未见狭窄及粥样斑块 ,颈动脉内膜厚度 /腔内径<0 .1。心绞痛或心肌梗死组其中 1例 (2 ,3% )颈动脉狭窄 >5 0 % ,80 % (34/ 42 )发现颈动脉粥样斑块 ,颈动脉内膜厚度 /腔内径 >0 .1,收缩期颈内动脉血流速 (IC) /颈总动脉血流速 (CC) >0 .8,与对照组比较均有显著差异 ,但心绞痛组与心肌梗死组上述指标未见显著差异。结论

AIM:To study the correlation between carotid atherosclerosis(CAS) and coronary atherosclerosis heart disease(CHD). METHODS:Fifty two patients were divided into three groups:control (10 cases),angina pectoral (16 cases) and myocardial infarction (26 cases) groups. The CHD patients were detected by ECG, 99m Tc MIBI stress rest myocardial perfusion SPECT and the CAS patients by ultrsound. RESUTS:In the control group,carotid ultrasound didn′t show carotid artery stenosis and atheresclerotic plaques,and the thickness of internal membrane of carotid/vascular cavity distance was below 0.1. In angina pectoral and myocardial inforction groups,only 1 case (2.3%) had >50% stenosis in carotid,carotid atherosclerotic plaques were found in 80% (34/42) of all the cases,the thinkness of internal membrane of carotid/vessel cavity distance was >0.1, IC/CC>0.8. There were signifiant difference between CHD group and contral group,but no significant difference between angina pectoral group and myocardial infarction group was found. CONCLUSIONS:There was a close correlation between carotid atherosclerosis and CHD.
