在美国,慢性高血压影响8%的育龄女性和高达6%的孕妇。合并慢性高血压的孕妇,其不良妊娠结局如先兆子痫、小于胎龄儿、早产、胎盘早剥和胎儿宫内死亡率升高3~5倍。在孕妇中,重度慢性高血压[≥160/100mm Hg(1mm Hg=0.133kPa)]的治疗无争议,但轻度慢性高血压的危险性则知道得很少,因为有报道显示在该血压范围内并不增加妊娠的危险。美国妇产科协会和其他机构也建议在怀孕期间轻度高血压(140~159/90~109mm Hg)不应该开始或应当
In the United States, chronic hypertension affects 8% of women of reproductive age and up to 6% of pregnant women. Pregnant women with chronic hypertension, adverse pregnancy outcomes such as preeclampsia, less than gestational age children, premature birth, placental abruption and intrauterine fetal mortality increased 3 to 5 times. In pregnant women, the treatment of severe chronic hypertension [≥ 160 / 100mm Hg (1mm Hg = 0.133kPa)] is undisputed but the risk of mild chronic hypertension is poorly understood as it has been reported that within this blood pressure range Does not increase the risk of pregnancy within. The American College of Obstetricians and Gynecologists and others also suggest that mild hypertension (140-159 / 90-109 mm Hg) should not be started or should be
