摘要 目的探讨血压异常节律变化类型对老年单纯收缩期高血压患者心脏功能和结构的影响。方法对94名老年单纯收缩期高血压患者进行24 h动态血压监测,同时行心脏超声多普勒检查。根据血压类型进行分组,观察不同血压类型的规律性变化,并将非杓型及反杓型血压类型与心脏功能和结构的各项指标进行分析。结果 24 h动态血压结果表明老年单纯收缩期高血压患者异常血压类型占93%;其中,非杓型血压类型占58%,反杓型血压类型占35%。反杓型组与非杓型组比较,主动脉根部内径(31.36±5.12 mm,26.57±4.49 mm)、室间隔厚度(11.21±2.50 mm,9.66±1.13 mm)、左室后壁厚度(9.76±1.41mm,9.02±1.02 mm)、每搏量(45.05±17.36 mL,61.10±16.24 mL)组间具有显著统计学差异(P<0.01);射血分数(46.26%±12.66%,55.21%±10.53%)、左室质量(224.89±43.32 g,192.72±61.02 g)、左室质量指数(124.13±22.54 g/m2,105.39±32.62 g/m2)组间具有统计学差异(P<0.05)。结论老年单纯收缩期高血压患者,血压异常节律变化是引起心脏靶器官损害的重要因素,其中反杓型血压节律变化使心脏功能和结构受损更为显著。
