颈动脉粥样硬化与冠状动脉病变的相关性研究

目的以冠状动脉造影结果为标准,对比分析B超检测颈动脉粥样硬化与冠状动脉病变的相关性,以探讨颈动脉粥样硬化与冠心病的关系及其临床意义.方法86例患者分成冠心病组和对照组,全部患者均经冠状动脉造影和B超检测颈动脉变化.结果超声检出颈动脉斑块预测冠心病的敏感性为87.75%;特异性为70.27%;阳性预测值为79.63%;阴性预测值为81.25%.颈动脉内膜中层最大值(IMTm)与冠状动脉粥样硬化程度积分相关分析成显著正相关(r=0.42,P＜0.01).结论B超检测颈动脉粥样硬化可作为预测冠心病的一个有价值的指标.

A STUDY OF CORRELATION BETWEEN CAROTID ATHEROSCLEROSIS AND CORONARY ATHEROSCLEROSIS

Objective To assess the correlation between carotid atherosclerosis observed by carotid ultrasound and coronary atherosclerosis by coronary angiography(CAG). Methods 86 patients were classified into two groups according to the results of CAG:coronary artery disease(CAD) group and control group.All patients were examined with carotid ultrasound and CAG. Results The sensitivities of carotid ultrasound for detecting CAD were 87.75%;The specificity were 70.27%;the positive predictive value were 79.63% and the negative predictive value were 81.25%.The correlation between maximal intima media thickness(IMTm) and the score of severity of coronary atherosclerosis are positive(r=0.42,P<0.01). Conclusion Corotid ultrasound detecting carotid atherosclerosis is valuable for predicting CAD.
