JAHA:血清钙和胰岛素抵抗与高血压风险之间的关联

2019-01-01 xing.T MedSci原创

由此可见,该研究的结果表明较高的血清钙水平可能先于外周IR而发生,这种单向关系在高血压的发生发展中起作用。

血清钙和胰岛素抵抗(IR)之间的时间顺序及其对高血压的影响尚不清楚。近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员探究了血清钙与IR之间的关联,以及在中国进行的纵向队列中评估了发生高血压事件的风险。

研究人员分析了来自8653名年龄20至74岁、平均随访5.3年的受试者的数据。在基线和随访时测量血清钙、空腹和2小时血清葡萄糖和胰岛素。交叉滞后和介导分析用于评估血清钙与IR之间的时间关系及其对高血压发病率的影响。

研究人员观察了基线血清钙和IR对随访时高血压的联合作用(HOMA_IR [肝IR] P=0.029,Gutt指数[外周IR] P=0.009)。从基线血清钙到随访外周IR的交叉滞后路径系数(β2)显著大于从基线外周胰岛素抵抗到随访血清钙的路径系数(β1)(β2=-0.354 vs. β1=-0.005; P=0.027)。然而,在血清钙与肝脏IR分析中没有观察到方向性关系。外周IR对基线时血清钙与随访期高血压之间相关性的介导作用估计为16.4%(P<0.001)。

由此可见,该研究的结果表明较高的血清钙水平可能先于外周IR而发生,这种单向关系在高血压的发生发展中起作用。
