Postpartum Recovery Trends in Women with Hypertensive Disorders of Pregnancy

The strength of this study was its prospective design and high rate of follow-up. Those who missed a visit were followed up over telephone. However, 19 women were not available even by phone. A limitation of this study is that the information regarding when the antihypertensive was stopped was obtained by patient recall, raising the possibility of recall bias. However, as the range of recovery times was wide, an error of few days may not be significant.

In the study we noted that women with preeclampsia took a longer time to recovery compared with women with gestational hypertension. Earlier and more severe disease was associated with delay to recovery or persistence of hypertension beyond 10 weeks postpartum.

Similar to our observation, other authors have observed a consistent association of time to reversion of hypertension and early-onset hypertension in pregnancy [3–5]. Ferrazzani explained the longer time to normalization of blood pressure in preeclampsia compared to gestational hypertension as the recovery time of the endothelial damage in preeclampsia [4].

Berks et al [6] found a correlation of maximum diastolic blood pressure, maximum proteinuria in pregnancy, and diagnosis-to-delivery interval with time taken for resolution of hypertension; however, they did not find that time to resolution was correlated with gestational age at onset of preeclampsia. They opined that their observations reflected endothelial recovery after preeclampsia. They also suggested further research in the area of temporizing management of preeclampsia to determine if a conservative approach increases remote cardiovascular risk [6]. We did not study the diagnosis-to-delivery interval, but those with early delivery in our group had late postpartum recovery, indicating that they had severe/complicated preeclampsia that demanded early termination.

In conclusion, women with advanced age, higher body mass index, early gestational age at the onset of hypertension, severe and with complications of hypertension require prolonged monitoring and treatment when indicated for hypertension in the postnatal period. Women with a history of pregnancy hypertension have increased risk of stroke, cardiac ischemia, venous thrombosis within 10 to 20 years after pregnancy and higher risk of hypertension and type 2 diabetes mellitus [7–9]. Extended postnatal follow-up and regular monitoring is recommended to address the needs of these high-risk women.
