摘要
目的 探讨血管回声跟踪技术定量评价健康志愿者颈动脉弹性参数及其影响因素,确定相关参数的正常值范围。方法 对143位健康志愿者[男性72例,女性71例,平均年龄(47. 2±14. 9)岁]应用血管回声跟踪技术获取双侧颈动脉的弹性系数(Ep)、僵硬度(β)及顺应性(AC)三项指标,并分析其与年龄、性别、心率和血压的关系。结果 ①年龄与Ep和β显著正相关而与AC显著负相关,收缩压与Ep显著正相关,性别、心率和舒张压与这些参数相关性不显著。②在20~29岁、30~39岁和40~49岁组中,随年龄增加Ep和β增高而AC减低;但在50~59岁和≥60岁组,各参数与40~49岁组之间差异无显著性意义,提示年龄对<40岁者颈动脉弹性参数影响显著,而对≥40岁者影响不显著。③Ep、β和AC的正常值在≥40岁者分别为117. 97±31. 04、8. 67±2. 23和0. 74±0. 21,而在<40岁者随年龄不同而异。结论 应用血管回声跟踪技术能够准确获取颈动脉性能参数,为临床定量评价颈动脉弹性提供了一种新的手段。
