Those most at risk are people over the age of 35, current or former smokers, or patients who delivered by cesarean section.
People with a history of high blood pressure may develop hypertension for the first time in the weeks and months following delivery, but there is little data on first-time hypertension that develops more than six weeks postpartum.
Postpartum hypertension may be persistent, following a pregnancy complicated by hypertension, or of new onset (Again), after a normal pregnancy. The aim of this study is to estimate the incidence and identify risk factors for postpartum hypertension. Again (HPPTN-DN) among a diverse safety net hospital population.
We conducted a retrospective cohort study of 3925 delivery From 2016 to 2018. All blood pressure (BP) measurements during pregnancy until 12 months after delivery were extracted from medical records. Patients with chronic hypertension or hypertensive pregnancy were excluded.
dn-PPHTN was defined as 2 separate BP readings with systolic BP ≥140 mm Hg and diastolic BP ≥90 mm Hg at least 48 h apart. Severe dn-PPHTN was defined as systolic BP ≥160 and diastolic BP ≥110. We examined risk factors individually and in combination and at the time of diagnosis.
among 2465 patients With no history of hypertension, 12.1% (n=298) developed dn-PPHTN; of whom 17.1% had severe dn-PPHTN (n=51).
compared to those without DN-PPHTN; Cases were more likely to be aged ≥35 years, delivered by cesarean section, or current or former smokers.
Patients with all of these features had a 29% risk of developing dn-PPHTN, which was increased among non-Hispanic black patients (36%). About 22% of cases were diagnosed after 6 weeks postpartum.
More than 1 in 10 patients with standard pregnancy experience dn-PPHTN in the year following delivery. Opportunities to monitor and manage patients at highest risk of dn-PPHTN throughout the postpartum year may reduce cardiovascular maternal morbidity.
Now, a new study led by a Boston University School of Public Health (BUSPH) researcher finds that 1 in 10 women who didn’t have high blood pressure before or during pregnancy had high blood pressure up to a year after giving birth. Hypertension may develop.
Published in Hypertension, a journal of American Heart AssociationThe study also found that nearly a quarter of these cases of high blood pressure developed six weeks or more after delivery, and mothers most at risk were over age 35, current or former smokers, or There were women who gave birth to their child by caesarean section.
Postpartum hypertension can lead to complications such as stroke, heart disease and kidney failure later in life, but until now, most research underestimated the burden of new-onset postpartum hypertension. Previous studies on this topic focused mainly on blood pressure measurements taken during delivery or hospitalization. In addition, standard postpartum care consists of only one clinic visit within four to six weeks after delivery, so new cases of high blood pressure may go undetected in the postpartum period (six weeks to one year after delivery).
