We evaluated carotid artery stiffness in patients with coronary artery disease (CAD) using acoustic radiation force impulse (ARFI) elastography and investigated the relationship between stiffness and CAD.
This study examined 76 CAD patients (aged 60.7 ± 11) and 70 healthy individuals (aged 59.6 ± 9). The left common carotid artery mean shear wave velocity (LCmeanSWV) and the right common carotid artery mean shear wave velocity (RCmeanSWV) of the anterior walls were measured using ARFI elastography, and the results of the patient group and the healthy group were compared. The common carotid intima-media thickness (CIMT) was measured in both groups and compared with mean SWV.
The RCmeanSWVs in the patient and healthy groups were 3.47 ± 1 m/s and 2.69 ± 0.90 m/s, respectively ( < 0.001). The LCmeanSWVs in the patient and healthy groups were 3.60 ± 0.9 m/s and 2.90 ± 0.80 m/s, respectively ( < 0.001). A significant correlation was found between the RCmeanSWV and the right CIMT values and between the LCmeanSWV and the left CIMT values (r = 0.231, = 0.03 and r = 0.331, = 0.002, respectively).
The mean SWV values of carotid arteries of CAD patients measured with ARFI elastography were significantly higher than the mean SWV values of the carotid arteries of healthy individuals. Thus, measurement of the carotid artery SWV could be a potential tool in the risk evaluation of cardiovascular disease. Nonetheless, new studies are required to determine whether this method serves as a useful additional tool.
应用声辐射力脉冲（ARFI）弹性成像技术评估冠心病（CAD）患者颈动脉僵硬度，并探讨僵硬度与 CAD 的关系。
本研究纳入 76 例 CAD 患者（年龄 60.7±11 岁）和 70 例健康对照者（年龄 59.6±9 岁）。采用 ARFI 弹性成像技术测量左颈总动脉前壁平均剪切波速度（LCmeanSWV）和右颈总动脉前壁平均剪切波速度（RCmeanSWV），比较两组间的差异。同时测量两组颈总动脉内中膜厚度（CIMT）并与平均 SWV 进行相关性分析。
CAD 组患者 RCmeanSWV 为 3.47±1 m/s，健康对照组为 2.69±0.90 m/s（ < 0.001）；CAD 组患者 LCmeanSWV 为 3.60±0.9 m/s，健康对照组为 2.90±0.80 m/s（ < 0.001）。RCmeanSWV 与右侧 CIMT 呈正相关（r = 0.231， = 0.03），LCmeanSWV 与左侧 CIMT 呈正相关（r = 0.331， = 0.002）。
应用 ARFI 弹性成像技术测量 CAD 患者颈动脉平均 SWV 值明显高于健康对照组，颈动脉 SWV 测量可能成为心血管疾病风险评估的潜在工具。但需要进一步研究以确定该方法是否作为一种有用的附加工具。
