【摘要】:目的探讨高血压患者血管超负荷指数(VOI)与颈动脉内膜中层厚度(CA-IMT)的关系。方法入选原发性高血压(EH)患者646例(男386例,女260例,包括未降压和已降压治疗者),年龄(62.2±12.3)岁。以内膜中层厚度(IMT)≥1.0mm为切点,分为IMT1.0mm组(n=376)和IMT≥1.0mm组(n=270)。选择同期未服用任何药物的门诊体检的正常血压者98人为对照组。测量身高、体质量、收缩压和舒张压。VOI=1.33×收缩压-0.33×舒张压-133.3mm Hg。清晨空腹测定血糖、血脂、肝肾功能、血常规和纤维蛋白原。采用高分辨率血管彩色多普勒超声心动图技术测定反应性充血前后肱动脉内径的变化率,作为血管内皮舒张功能(FMD)。测定双侧CA-IMT,当任何一侧颈动脉有斑块形成时,CA-IMT记为1.5mm。同时检查超声心动图,计算左心室质量指数(LVMI)。结果高血压患者FMD随着VOI、LVMI和左心室质量/身高2.7(LVM/H2.7)增加而减弱。与IMT1.0mm组比较,IMT≥1.0mm组VOI、LVMI和LVM/H2.7增加,而FMD减弱(均P0.05)。多元逐步回归分析显示,VOI是所有对象CA-IMT的影响因素,VOI每升高10mm Hg,CA-IMT增厚0.05mm。分层分析显示,无论哪个年龄段和性别,以及合并危险因素的多少,VOI都是EH患者CA-IMT的影响因素。结论 VOI是EH患者CA-IMT的重要影响因素。
