摘要
目的探讨颈动脉彩色多普勒超声(CDFI)检测老年女性高血压患者颈动脉内膜中层厚度(IMT)的价值。方法选取2019年1月至2019年10月上海市第一人民医院宝山分院收治的82例老年女性高血压患者。根据患者高血压测量结果分为正常组25例、增厚组43例和斑块组14例;根据患者动态血压变异性水平,以9.57作为临界值,分为低动态血压变异性组42例(7.02~9.57)和高动态血压变异性组40例(9.57~14.29)。比较不同IMT组血压变异指数差异;不同动态血压变异性组IMT差异。结果增厚组与斑块组24 hDBP、24 h SBP、dDBP、dSBP、nDBP及nSBP等动态血压水平高于正常组,且斑块组高于增厚组,差异有统计学意义(P<0.05)。增厚组与斑块组24 hSBPV、24 hDBPV、dSBPV、dDBPV、nSBPV及nDBPV等动脉血压变异水平高于正常组,且斑块组高于增厚组,差异有统计学意义(P<0.05)。高动态血压变异性组左侧颈总动脉内膜中层厚度、右侧颈总动脉内膜中层厚度、左侧颈内动脉内膜中层厚度及右侧颈内动脉内膜中层厚度和斑块发生率均高于低动态血压变异性组,差异有统计学意义(P<0.05)。结论颈动脉CDFI检测老年女性高血压患者IMT可对动态血压变异性指数进行有效评价。
【Objective】 To investigate the value of carotid color Doppler ultrasound in detecting carotid intima-media thickness in elderly women with hypertension.【Methods】Eighty-two elderly women with hypertension were selected, and carotid color Doppler ultrasound was used to measure the carotid intima-media thickness. The patients were divided into normal group(n=25),thickened group(n=43) and plaque group(n=14) according to the measurement results, and divided into high ambulatory blood pressure variability group(n=40) and hypoaemia variability group(n=42) according to ambulatory blood pressure variability. The differences of blood pressure variability index in different carotid intima-media thickness groups and the differences in carotid intima-media thickness in patients with different ambulatory blood pressure variability groups were compared.【Results】 Blood pressure levels in the thickened group and the plaque group were significantly increased, and the plaque group was higher than the thickened group(P<0.05). The 24 hDBPV, 24 hSBPV, dDBPV, dSBPV, nDBPV, and nSBPV indexes of the thickened group and the plaque group were significantly increased, and all indicators of the plaque group were higher than those of the thickened group(P<0.05).The carotid intima-media thickness and the incidence of plaque in the patients with high ambulatory blood pressure variability were higher than those in the low ambulatory blood pressure variability(P<0.05).【Conclusion】 Carotid color Doppler ultrasound detection of carotid intima-media thickness in elderly women with hypertension can effectively evaluate the dynamic blood pressure variability index.
