摘要: 目的 探究肿瘤坏死因子样凋亡微弱诱导剂(TWEAK)与原发性高血压患者心脏重塑的关系。 方法 选取原发性高血压5年以上患者88例为高血压组,检测血清TWEAK水平并分为高表达组(n=51)和低表达组(n=37);选取同期健康体检者20例为对照组。采用RT-PCR 法检测入选者外周血单个核细胞(PBMCs)中TWEAK mRNA表达量,采用ELISA法检测血清中可溶性TWEAK(sTWEAK)和基质金属蛋白酶1(sMMP-1)表达水平;超声心动图测量左心房直径(LAD)、左心房容积(LAV)、左心房容积指数(LAVI)、二尖瓣血流频谱舒张早期波E峰(E)、二尖瓣血流频谱心房收缩波A峰(A)、二尖瓣环舒张早期与心房收缩期峰值运动速度比(E/A),二尖瓣环侧壁运动频谱峰值比值(E/E')。 结果 高表达组和低表达组sTWEAK、TWEAK mRNA、sMMP-1水平均高于对照组(P<0.05),且高表达组显著高于低表达组(P<0.01);高表达组和低表达组LAVI、E/E'均高于对照组(P<0.05),且高表达组显著高于低表达组(P<0.01);sTWEAK、TWEAK mRNA与sMMP-1、LAVI、E/E'呈显著正相关性(P<0.01)。 结论 高血压患者心脏重塑可能与TWEAK高表达有关。
