二甲双胍又“闪光”:可防腹主动脉瘤扩张

2019-10-16 卢芳 中国循环杂志

腹主动脉瘤就像体内埋伏的“炸弹”,扩张到一定程度就会发生破裂大出血。一项美国研究发现,得糖尿病的无症状腹主动脉瘤患者中,那些处方二甲双胍者的腹主动脉瘤就生长得慢。研究显示,在整个队列中,多元线性回归模型分析显示,腹主动脉瘤平均增长率为1.4 mm/年;多元混合效应模型分析显示,腹主动脉瘤平均增长率为1.3 mm/年。未校正前,二甲双胍组腹主动脉瘤平均增长率为1.2 mm/年,非二甲双胍组的腹主动脉

腹主动脉瘤就像体内埋伏的“炸弹”,扩张到一定程度就会发生破裂大出血。

一项美国研究发现,得糖尿病的无症状腹主动脉瘤患者中,那些处方二甲双胍者的腹主动脉瘤就生长得慢。

研究显示,在整个队列中,多元线性回归模型分析显示,腹主动脉瘤平均增长率为1.4 mm/年;多元混合效应模型分析显示,腹主动脉瘤平均增长率为1.3 mm/年。

未校正前,二甲双胍组腹主动脉瘤平均增长率为1.2 mm/年,非二甲双胍组的腹主动脉瘤平均增长率为1.5 mm/年(P <0.001)。

进一步分析可见,多元线性回归模型分析显示,使用二甲双胍使得腹主动脉瘤平均增长率降低了0.23 mm/年。

应用多元混合效应模型分析显示,使用二甲双胍增长率降低了0.2 mm/年。

在腹主动脉瘤在35~49 mm的7462例患者中进行的分析显示,结果也是一样。

这项研究分析了2003~2013年退伍军人卫生保健系统13834例无症状腹主动脉瘤糖尿病患者,腹主动脉瘤平均诊断年龄为70岁,男性占99%。其中有39.7%的患者在确诊腹主动脉瘤后半年内服用了二甲双胍。平均随访4.2年。

而近期一项纳入8项研究29587例参与者的Meta分析研究也显示,老药二甲双胍对这种“炸弹”有限制作用。
