【摘要】：目的超声评估颈动脉斑块卒中风险等级与冠状动脉病变严重程度关系,探讨颈动脉斑块易损性预测冠状动脉病变临床价值。方法选取117例冠心病患者行颈动脉超声检查,按照斑块性质分为易损斑块组与稳定斑块组,按照管腔狭窄程度分为轻度狭窄组与中度以上狭窄组,分别比较两组患者冠状动脉狭窄严重程度的Gensini评分差异度。评价每位患者颈动脉斑块卒中风险等级,比较不同风险等级组冠状动脉狭窄严重程度的Gensini评分差异度。结果颈动脉易损斑块组Gensini评分明显高于颈动脉稳定斑块组。颈动脉管腔轻度狭窄组(30%)与中度以上狭窄组(≥30%)的Gensini评分差异无统计学意义。颈动脉斑块高、极高度风险等级组冠脉Gensini积分明显高于低、中度风险组,有统计学意义。结论颈动脉斑块性质及斑块发生缺血性脑卒中风险等级在一定程度上能够推测冠状动脉硬化狭窄严重程度。
[Abstract]:Objective to evaluate the relationship between the severity of coronary artery disease and the risk of carotid plaque stroke by ultrasound. Methods 117 patients with coronary artery disease were selected for carotid ultrasound examination and divided into vulnerable plaque group and stable plaque group according to the nature of plaque. According to the degree of lumen stenosis, the patients were divided into mild stenosis group and moderate stenosis group. The Gensini score differences of coronary artery stenosis severity were compared between the two groups, and the risk level of carotid plaque stroke was evaluated in each patient. Results the Gensini score of carotid vulnerable plaque group was significantly higher than that of carotid artery stable plaque group. Mild stenosis group (. There was no significant difference in Gensini score between the group with moderate stenosis (鈮，
