子痫前期是妊娠期常见的、涉及多系统的功能紊乱性疾病，对孕妇和胎儿都有风险。目前所有预防措施中低剂量阿司匹林的研究最为全面，2019年ACOG指南推荐12周后子痫前期高风险的孕妇服用低剂量阿司匹林作为PE的重要预防措施。WHO推荐钙补充剂作为预防PE的措施之一，特别是在低血钙、饮食钙摄入不足的人群。其他药物、抗氧化剂、钠摄入控制的预防目前证据不足且尚存争议。本文将重点对子痫前期预防的最新指南、研究进展进行综述。“,”Preeclampsia is a common gestational disease, involves multisystem disorder and carries risks for both mother and baby.
