目的

分析颈动脉超声造影阳性斑块数目、斑块最大厚度与多个血清标志物的相关性。

方法

选取2016年5月至2017年4月在北京安贞医院超声科进行颈动脉超声造影检查患者210例,检查部位包括两侧颈总动脉、颈动脉分叉部、颈内动脉近端及颈外动脉,采用统一标准定义颈动脉斑块,记录斑块数目与斑块最大厚度。斑块内≥1个区域出现造影剂灌注定义为斑块内新生微血管阳性。患者空腹12 h采集肘静脉血,分离血清,使用全自动生化分析仪检测下列8项血清标志物,即总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、空腹血糖(FBG)、超敏C反应蛋白(hsCRP)、同型半胱氨酸(Hcy)、脂蛋白相关磷脂酶A2(Lp-PLA2)与小而密低密度脂蛋白胆固醇(sdLDL-C)。根据斑块数目将患者分为4组,Ⅰ组88例,Ⅱ组84例,Ⅲ组25例,Ⅳ组13例,单因素方差分析或非参数检验比较年龄、性别、斑块最大厚度以及上述血清标志物的差异,4组有统计学意义的指标采用LSD-t检验进行两两比较,不同性别组有统计学差异的指标按性别进行亚组分析。此外分析斑块数目、斑块最大厚度与年龄及上述血清标志物的相关性。

结果

共入选210例颈动脉超声造影患者,斑块内新生微血管均为阳性,斑块数目为1~4个。4组间比较HDL-C、空腹血糖差异有统计学意义(F=2.810、5.447,P均<0.05),其他血清标志物及斑块最大厚度,差异均无统计学意义(P均>0.05)。HDL-C两组间比较发现,Ⅰ组与Ⅲ组、Ⅳ组,差异均有统计学意义(t=2.525、2.035,P均<0.05)。空腹血糖两两组间比较发现,Ⅰ组、Ⅱ组、Ⅲ组与Ⅳ组,差异均有统计学意义(t=-2.645、-3.140、-2.652,P均<0.05)。相关性分析同样表明斑块数目与HDL-C、空腹血糖有关联(r=-0.202、0.224,P均<0.05),男性组斑块数目还与hsCRP有关(r=0.184,P<0.05)。相关性分析显示,男性患者年龄与斑块最大厚度有相关性(r=0.287,P<0.001)。

结论

对于颈动脉超声造影阳性斑块,血清HDL-C、空腹血糖、男性hsCRP水平可以反映斑块数目,并证实颈动脉斑块厚度与年龄有明显相关性。

Objective

To investigate the possible correlation between ultrasound features of carotid plaques positive for neovascularization according to contrast-enhanced ultrasound (CEUS) and eight serum biomarkers.

Methods

Patients who had one or more carotid plaques were included primarily and then examined by CEUS. Finally, 210 patients whose carotid plaques were all positive for neovascularization were included. Two carotid plaque features including carotid plaque number and maximum plaque height (MPH) were recorded. All subjects were divided into four groups (I-IV) according to the number of carotid plaques. Eight serum biomarkers including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), high-sensitivity C-reactive protein (hsCRP), homocysteine (Hcy), lipoprotein-associated phospholipase A2 (Lp-PLA2), and small and dense LDL-C (sdLDL-C) were measured with an automatic biochemistry analyzer.

Results

The participants had a mean (standard deviation [SD]) age of 60.73 (8.59) years, with 83% being male. HDL-C levels and FBG levels were statistically different among the four groups (F=2.810 and 5.447, respectively; P<0.05). HDL-C level in group I were statistically different from those in groups III and IV (t=2.525 and 2.035, respectively; P<0.05). FBG levels in groups I, II, and III were statistically different from that of group IV, (t=-2.645, -3.140, and -2.652, respectively; P<0.05). Correlation analysis showed that carotid plaque number was correlated with HDL-C levels and FBG levels, separately (r=-0.202 and 0.224, respectively; P<0.05). In male patients, carotid plaque number was also correlated with hsCRP levels (r=0.184, P<0.05). There was a good correlation between MPH and age (r=0.253, P<0.001), especially in male patients (r=0.287, P<0.001).

Conclusion

For carotid plaques with neovascularization, serum HDL-C, FBG, and male hsCRP levels can possibly predict the number of carotid plaques. The MPH of carotid plaques is associated with age.
