[摘要]目的探讨血压昼夜节律异常与老年高血压病人心功能损害的关系。方法选择老年高血压病人117例，其日间血压均维持在较稳定范围内，根据夜间血压下降率分为勺型组、非勺型组和反勺型组。比较3组病人的动态血压监测指标及心脏结构和功能参数。结果勺型、非勺型、反勺型组病人夜间收缩压依次递增，夜间舒张压依次递减，3组病人夜间收缩压和夜间舒张压比较差异有统计学意义(F=6.060、6.755，P<0.05)。3组病人的心脏结构和功能参数比较，室间隔厚度、舒张期左心室后壁厚度、E峰减速时间和二尖瓣舒张早期血流峰速度/二尖瓣舒张早期运动峰速度差异均有统计学意义(F=4.190～7.051，P<0.05)。结论血压昼夜节律异常可导致老年高血压病人心脏舒张功能损害，尤以反勺型损害最重，其次为非勺型。

    [ABSTRACT]ObjectiveTo investigate the association between abnormal circadian blood pressure pattern and cardiac dysfunction in elderly hypertensive patients. MethodsA total of 117 elderly hypertensive patients were enrolled and their daytime blood pressure was controlled within a relatively stable range. According to the rate of blood pressure drop at night ......
