颈动脉超声对冠心病的预测价值研究

目的探讨颈动脉硬化程度与冠心病血管病变程度及临床症状的关系，判断颈动脉超声对冠心病的预测价值。方法可疑冠心病130例患者同时行颈动脉超声及冠状动脉造影检查，分别按冠脉临床症状及冠脉病变程度分组对照观察。结果在颈动脉病变超声结果与临床症状差方分析中，二者结果具有很好的相关性（P〈0．05），相关程度r=0．581，颈动脉病变与冠状动脉造影病变严重程度亦有良好的正相关性（P〈0．05），相关程度r=0．49。结论颈动脉硬化程度与冠心病临床表现及冠状动脉病变程度均具由相关性，颈动脉超声对冠心病有一定的预测价值，可作为冠心病的早期预测因素。

Predictive value study of Carotid ultrasound for coronary artery disease

Objective To investigate the correlation of the extent of carotid artery atherosclerosis, coronary artery stenosis and clinical symptom, to confirm the predictive value of carotid ultrasonography for coronay arterydisease（CAD）. Methods Carotid ultrasonography and coronary angiography （CAG）were achieved among 126 suspected CAD. The resuhs of carotid uhrasonography, CAG （certify the degree of coronary stenosis） and clinical symptom were analyzed with analysis （ANOVA）. Results （1）ANOVA demonstrated carotid ultrasonography and clinical symptom had positive correlation （ P 〈 0. 05 ）, r = 0. 581 P 〈 0. 05 ; （2）The severity of CAD was correlated with the extent of carotid artery atherosclerosis, there was a positive correlation （ P 〈 0. 05 ） , r = 0. 499 （ P 〈 0. 05）. Conclusion The extent of carotid artery atherosclerosis is closely correlated with presence of CAD. It is possible to predict coronary artery atherosclerosis by carotid ultrasound. It seemed to be earlier predictive index for CAD.
