Hypertension:宫内降压药暴露与新生儿结局

2019-12-30 xing.T MedSci原创

由此可见,高血压是低出生体重和早产的关键危险因素。尽管早产可能与妊娠期间服用降压药有关,但这些关联可能反映出高血压的严重程度增加,需要进行治疗。

妊娠期间高血压疾病是对母亲和胎儿的重要危险因素,经常需要进行降压治疗。描述妊娠期间接受降压治疗的安全性数据相互矛盾,许多研究存在重大的方法学问题,例如研究设计不当,样本量小且没有未经治疗的对照组。

近日,心血管权威杂志Hypertension上发表了一篇研究文章,研究人员进行了一项回顾性队列研究,该研究使用了定期收集的相关医疗记录,对苏格兰2010-2014年出生的268711名儿童进行了评估,以探究宫内接触降压药物后的结局。

研究人员确定了研究期间出生的由265488名合格条件的儿童组成的队列。其中,2350人在子宫内接触过降压药治疗,4391人暴露于治疗后的迟发性高血压,而7971人暴露于未经治疗的妊娠期高血压。未经治疗的高血压与早产(风险比[aRR],1.15 [99%CI,1.01–1.30])、低出生体重(aRR,2.01 [99%CI,1.72–2.36])和体重小于胎龄(aRR,1.50 [99%CI,1.35-1.66])风险增加有关,而宫内降压药暴露也与早产(aRR,3.12 [99%CI,2.68–3.64])、低出生体重(aRR, 2.23 [99%CI,1.82-1.52])和体重小于胎龄(aRR,2.13 [99%CI,1.81-2.52])相关。迟发性高血压还与早产(aRR,2.21 [99%CI,1.86-2.62])、低出生体重(aRR,2.06 [99%CI,1.74-2.43])和小于胎龄( aRR,1.90 [99%CI,1.68–2.16])有关。

由此可见,高血压是低出生体重和早产的关键危险因素。尽管早产可能与妊娠期间服用降压药有关,但这些关联可能反映出高血压的严重程度增加,需要进行治疗。
