目的探讨利用高频超声检测冠心病患者颈动脉内膜一中膜厚度及斑块的临床意义。方法利用高频超声检测40例冠心病患者(为观察组)颈动脉内膜一中膜厚度及斑块数量,选择40例健康查体者做为对照组,对两组检测结果进行对比分析。结果观察组颈总动脉内膜一中膜厚度(CCAIMT)值、颈内动脉分叉处内膜一中膜厚度(CCABIMT)值、颈总动脉内膜一中膜厚度/内径比值(IMT/D)、颈内动脉血流速度和颈总动脉血流速度比值(IC/CC)均大于对照组,观察组颈动脉钙化斑发生率明显高于对照组,发生部位多见于颈总动脉分叉处,其次颈总动脉及颈内动脉。两组比较,差异均具有统计学意义(P<0.05)。结论超声检测颈动脉鉴别冠心病患者的类型特征和严重程度,为临床诊断提供客观指标和依据。
Objective To investigate the clinical significance of detecting the intima-media thickness and plaque of carotid artery in patients with coronary heart disease by using high-frequency ultrasound. Methods 40 cases of coronary heart disease (observation group) of carotid artery intima-media thickness and plaque number were detected by high-frequency ultrasound. Forty healthy subjects were selected as the control group, and the results of the two groups were compared. Results The carotid artery intima-media thickness (CCAIMT) value, carotid arterial bifurcation intima-media thickness (CCABIMT) value, carotid arterial intima-media thickness / inner diameter ratio (IMT / D ), ICA and CCI were higher than those in the control group. The incidence of carotid artery calcification in the observation group was significantly higher than that in the control group. The site of occurrence was more common in the common carotid artery bifurcation , Followed by the common carotid artery and internal carotid artery. The differences between the two groups were statistically significant (P <0.05). Conclusions Ultrasonic examination of the carotid artery to identify the type and severity of patients with coronary heart disease, for clinical diagnosis to provide objective indicators and basis.
