早期应用彩色多普勒超声诊断清晨高血压患者动脉粥样硬化的价值

The Value of Early Application of Color Doppler Ultrasound in the Diagnosis of Atherosclerosis in Early Morning Hypertension Patients

目的:探讨早期彩色多普勒超声检查对清晨高血压患者动脉粥样硬化的诊断价值.方法:选取2017年7月-2019年7月本院收治的清晨高血压患者60例为观察组,选取同期于本院住院的非清晨高血压患者60例为对照组.两组患者均进行颈动脉彩超及心脏彩超检查,比较两组超声检查动脉硬化情况及左心室心肌重量(LVM)、左心室心肌质量指数(LVMI)、颈动脉内膜-中层厚度(CCA-IMT)、颈总动脉分叉处内膜-中层厚度(BIMT)及Crouse积分.结果:观察组IMT增厚、斑块形成、血管狭窄的发生率均显著高于对照组,差异均有统计学意义(P<0.05).观察组的LVM、LVMI、CCA-IMT、BIMT及Crouse积分均显著高于对照组,差异均有统计学意义(P<0.05).ROC曲线示LVMI、CCA-IMT及Crouse积分线下面积均在0.6~0.8,诊断准确性中等.结论:通过彩色多普勒超声能够判断清晨高血压患者外周血管壁及心室壁情况,应尽早应用,及时了解掌握患者病情进展,对预防心脑血管疾病突发有着重要意义.

Objective:To explore the diagnostic value of early color Doppler ultrasound in early morning hypertension patients with atherosclerosis.Method:Sixty early morning hypertension patients admitted to our hospital from July 2017 to July 2019 were selected as the observation group,and sixty non-early morning hypertension patients hospitalized in our hospital during the same period were selected as the control group.Carotid ultrasonography and cardiac echocardiography were performed in both groups.The arteriosclerosis of ultrasound examination,Left ventricular myocardial weight(LVM),Left ventricular mass index(LVMI),carotid intima-media thickness(CCA-IMT),Bimodal thickness(BIMT)and Crouse score were compared between the two groups.Result:The incidence of IMT thickening,plaque formation and vascular stenosis in the observation group were significantly higher than those in the control group,the differences were statistically significant(P<0.05).LVM,LVMI,CCA-IMT,BIMT and Crouse scores in the observation group were significantly higher than those in the control group,the differences were statistically significant(P<0.05).ROC curve showed that LVMI,CCA-IMT and Crouse integral area were 0.6-0.8,with moderate diagnostic accuracy.Conclusion:Color Doppler ultrasound can be used to determine the peripheral blood vessel wall and ventricular wall of patients with early morning hypertension,so it should be applied as early as possible to timely understand and grasp the patient’s disease progression,which is of great significance to prevent the sudden occurrence of cardiovascular and cerebrovascular diseases.
