目的 探讨动态血压监测对识别妊娠期白大衣高血压(WCH)的意义及其预后。方法 选取2012—2013年在复旦大学附属妇产科医院接受动态血压监测的140例妊娠期妇女，以行动态血压监测时间为入组时间，以当时诊断为初始诊断，以分娩时诊断为最终诊断。结果 动态血压监测有助于识别妊娠期WCH。WCH组有9例(17%)最终发生了先兆子痫，有19例(36%)最终发生了妊娠高血压。结论 妊娠各期均有可能出现WCH。虽然当时不必接受药物治疗，但整个孕期需要持续监测血压。WCH的妊娠结局较好。

Objective To investigate the value of ambulatory blood pressure monitoring (ABPM) for identifying white coat hypertension (WCH) during pregnancy and predict the prognosis. Methods A total of 140 pregnant women who underwent ABPM in Obstetrics and Gynecology Hospital of Fudan University between 2012 and 2013 were enrolled in the present study. The enrollment time was the time pregnant women underwent ABPM. The initial diagnosis was the diagnosis made at the time pregnant women underwent ABPM. The final diagnosis was the diagnosis made at the time of delivery. Results ABPM was helpful for identifying the WCH during pregnancy. Among pregnant women with WCH, 9 of them (17%) finally developed preeclampsia and 19 of them (36%) finally developed gestational hypertension. Conclusion WCH may occur at each stage of pregnancy. Although it is not necessary to receive drug therapy, the blood pressure should be monitored continuously during pregnancy. The outcome of pregnant women with WCH is good.
