Postpartum recovery trends in women with hypertensive disorders of pregnancy

Objective: To examine the association of the patient's obstetric profile and time to normalization of blood pressure in the postnatal period among women with hypertensive disorders in pregnancy. Methods: We conducted a prospective cohort study at a tertiary level hospital between November 2014 and May 2015. Women with pregnancy hypertension who required antihypertensive treatment were recruited after delivery. The normalization trends in blood pressure were tested for associations with patient demographic data and details of pregnancy hypertension. Results: Among 109 women included in the study, earlier gestational age at onset of hypertension and earlier gestational age at delivery was correlated with slower resolution of hypertension. Time to resolution also was correlated with age, BMI, severity of hypertension, associated complications, and the number of antihypertensive medications received. There was no correlation with highest recorded systolic or diastolic blood pressures. Only 15% of women with gestational hypertension had persistent hypertension beyond 6 weeks. In the groups with nonsevere preeclampsia, severe preeclampsia, and eclampsia, blood pressure remained high after 6 weeks in 26%, 14%, and 50% of women, respectively. Conclusion: Women with advanced age, higher body mass index, early gestational age at the onset of hypertension, severe hypertension and who had complications of hypertension require prolonged monitoring and treatment when indicated for hypertension in postnatal period.
