目的评价颈动脉粥样硬化程度与冠状动脉病变严重程度的关系及其预测价值。方法将208例患者进行冠状动脉造影检查后,根据病变有无分为冠心病组116例和非冠心病组92例,同时对两组患者均进行双侧颈动脉超声检查,测定颈动脉病变程度。结果对颈动脉粥样硬化Crouse积分、等级积分和斑块数比较,冠心病组与非冠心病组差异显著,有统计学意义(P<0.001)。随着颈动脉病变严重度增加,狭窄<50%、50%≤狭窄<70%、狭窄≥70%三组比较差异有统计学意义(P<0.001)。同时对颈动脉斑块严重度Crouse积分及冠脉病变Gensini积分进行相关性分析,两者呈正相关,P<0.05。结论测定颈动脉粥样硬化病变的程度对冠状动脉的病变程度具有一定的预测意义,并对疑似冠心病患者及高危人群进行早期筛检和干预治疗具有重要意义。
Objective To evaluate the relationship between the severity of carotid atherosclerosis and the severity of coronary artery disease and their predictive value. Methods 208 patients undergoing coronary angiography were divided into coronary heart disease group (116 cases) and non-coronary heart disease group (92 cases). At the same time, bilateral carotid artery ultrasonography was performed in both groups to determine the degree of carotid artery disease . Results Compared with Crouse score, rank score and plaque score of carotid atherosclerosis, there was significant difference between coronary heart disease group and non-coronary heart disease group (P <0.001). With the severity of carotid artery disease increased, the stenosis of <50%, 50% ≤ stenosis <70%, stenosis ≥ 70% had significant difference between the three groups (P <0.001). At the same time, Crouse integral of carotid plaque and Gensini integral of coronary artery were analyzed. The correlation was significant (P <0.05). Conclusion The determination of the extent of carotid atherosclerosis has some predictive value on the severity of coronary artery disease. It is of great significance for early screening and intervention in patients with suspected coronary heart disease and high-risk population.
