Mothers could develop high blood pressure months after childbirth
By American Heart Association News
在怀孕期间和分娩后立即监测女性的血压是标准做法. 但一家医疗中心的新研究表明，如果在六周后停止这种做法，一些没有高血压史的新妈妈可能会错过这种情况.
这项研究周二发表在《沙巴体育平台点击进入》上 Hypertension, showed about a fifth of women who developed high blood pressure, also called hypertension, 产后随访护理结束后首次确诊. 黑人女性和35岁以上的女性患病风险尤其高, delivered by cesarean section or were current or former smokers.
“我们对分娩后超过六周的病例数量感到惊讶," lead study author Samantha Parker said in a news release. 帕克是波士顿大学公共卫生学院流行病学助理教授. “在此期间进行监测可以减轻严重的产后和长期心血管并发症."
产后高血压通常在分娩后立即发现，或在妇女最后一次产后检查时发现, typically four to six weeks after the baby is delivered. 在那次访问之后，几乎没有关于高血压诊断的数据, 因为大多数研究使用分娩期间或母亲还在医院时测量的血压. But doing so captures only the most severe cases, 哪些与危及生命的并发症(如中风)有关, heart attacks and kidney failure.
众所周知，在怀孕前或怀孕期间患有高血压的女性在以后的生活中患心脏病的风险更大. 但是对于产后首次患高血压的女性患心脏病的风险知之甚少.
以前的研究也表明，产后第一次患高血压的几率可能高达2.5 times more common among Black women than their white peers. 这项新研究观察了一组接受产前护理并在波士顿医疗中心分娩的不同种族妇女分娩后一年的高血压风险.
Researchers analyzed 2,465份2016年至2018年无慢性高血压病史妇女分娩的医疗记录. 在这项研究中，高血压被定义为收缩压(“顶”值)为140毫米汞柱或更高，舒张压(“底”值)为90毫米汞柱或更高.
Blood pressure was measured at least 48 hours after delivery. 从分娩后第一年的医疗记录中进行了额外的测量.
Overall, 在研究中，12%没有高血压病史的女性在分娩后一年内出现了高血压. While most cases were diagnosed shortly after delivery, 22%的人在婴儿出生六周后才被诊断出来.
Risk factors for new-onset hypertension included being 35 and older, having a C-section or being a current or former smoker. Risk also was higher among Black women.
“更多地了解产后六周以上的高血压，可能会让我们对警报有更深入的了解 racial disparities in maternal health," Parker said.
Future research, she said, 是否应该关注与产后高血压相关的其他不良结果, such as hospital readmissions, subsequent pregnancy complications and cardiovascular disease.
