摘要
目的 研究冠状动脉病变的严重程度与超声检测颈动脉结构和功能变化的相关性。方法 选择行冠状动脉造影的可疑冠心病患者 5 6例 ,应用B型超声对颈动脉进行扫查 ,动脉粥样斑块的定义为内 中膜厚度≥ 1.3mm。其中 5 0例进行经冠状动脉造影。颈动脉横断面顺应性、容积扩张性和僵硬指数作为评价颈动脉缓冲功能的指标。结果 5 6例患者合并颈动脉粥样斑块者 3 0例 ,与未合并颈动脉粥样斑块的患者相比 ,合并颈动脉粥样硬化患者冠脉 2支和 3支血管病变的发生率显著增加 (P <0 .0 0 1)。结论 并发颈动脉粥样斑块与冠脉多支血管病变密切相关 ,超声有助于早期检测外周大动脉损害 ,这对于指导治疗和预防冠脉事件是极其有益的。
Objective To explore the relationship between carotid arterial structure and severity of coronary lesion. Methods Fifty six cases of coronary heart disease were studied, B mode ultrasound was applied to examine the carotid artery, and common carotid artery intima media thickness ≥1.3mm was defined as a plaque. Fifty cases underwent coronary angiography for confirming the severity of coronary artery disease. Carotid cross sectional compliance, volume distensibility and stiffness indexes were used to reflect large arterial buffering function. Results Thirty cases presented carotid plaque. Incidence of lesions of 2 or 3 coronary branches in patients with carotid plaque were significantly higher than that of patients without carotid plaque ( P <0.001). Conclusion Carotid plaque has close relationship with multi branch coronary disease, B mode ultrasound is helpful for early detection of large arterial damage, so it is of great benefit to instructing medication and coronary events prevention.
