颈动脉超声检测对冠心病及其危险因素的临床意义

Clinical Significance of Carotid Ultrasonography on Coronary Heart Disease and Its Risk Factors

目的分析颈动脉超声检测对冠心病和其危险因素的临床意义。方法在2014年1月—2017年1月期间,对该院入选的60例患者进行了冠状动脉造影检查,并依据检查结果分成单支病变(n=20)、双支病变(n=20)以及三支病变(n=20),对冠心病危险因素、冠状动脉病变支数、颈动脉超声联系以及冠状动脉造影超声的关系进行研究。结果 60例患者的比较中,三支病变组的患者其收缩压等指标高于其他两组,其MT和斑块支数高于其他两组,单支病变的MT、PI、内径和RI结果分别为(0.79±0.17)mm、(1.09±0.77)、(0.70±0.14)cm以及(0.69±0.08),三支病变上述指标分别为(1.32±0.26)mm、(2.24±0.82)、(0.75±0.16)cm以及(0.80±0.10),三支病变组颈动脉的RI率高于单支病变,3组的颈动脉内径比较差异无统计学意义(P>0.05)。结论进行颈动脉超声的检查能够有效对冠状动脉病变严重指数进行分辨,同时能够对冠心病的高危患者进行筛查。

Objective This paper tries to analyze the clinical significance of carotid ultrasonography on coronary heart disease and its risk factors. Methods 60 patients admitted and received the carotid ultrasonography in this hospital from January 2014 to January 2017, and were divided into one-vessel lesion, two-vessel lesion and three-vessel lesion,with 20 cases in each group. Coronary heart disease risk factors, coronary artery lesion vessels, carotid ultrasound, and coronary angiography were studied. Results Compared with the other two groups, the percentage of MT and plaque in the patients with three-vessel lesion was higher than that in the other two groups. The MT, PI, internal diameter and PI of the one-vessel lesion was（0.79±0.17）mm,（1.09±0.77）,（0.70±0.14）cm and（0.69±0.08） respectively, and those of the three-vessel lesion was（1.32 ±0.26）mm,（2.24 ±0.82）,（0.75 ±0.16）cm and（0.80 ±0.10） respectively. RI rate of Carotid artery of the three-vessel lesion was higher than that of the one-vessel lesion, and the carotid artery inner diameter of three groups,the difference was not statistically significant（P0.05）. Conclusion Carotid ultrasonography can effectively distinguish the index of severe coronary artery disease, and can screen patients with high risk coronary heart disease.
