Among patients with hypertensive disorders of pregnancy using remote blood pressure monitoring, 31.5% achieved hypertension resolution within 6 weeks, taking an average of 15.0 days.

Postpartum hypertension resolution takes an average of 15 days, extending beyond the typical 2-week period, highlighting the need for longer-term remote blood pressure monitoring.
Introduction: Postpartum hypertension is a leading cause of severe maternal morbidity, yet most patients receive a single blood pressure (BP) check before the 6-week visit. Remote BP monitoring (RBPM) programs address this gap by enabling continuous postpartum surveillance. At a large safety-net hospital, patients with hypertensive disorders of pregnancy (HDP) were provided RBPM cuffs as part of routine postpartum care, allowing for daily BP tracking. This cohort study estimated time to hypertension resolution during the first 6 weeks (42 days) postpartum among RBPM patients, overall and by HDP subtype. Hypothesis: Time to hypertension resolution is expected to be longest among patients with preeclampsia, often the most severe HDP subtype, compared to those with gestational or de novo postpartum hypertension. Methods: This cohort study included patients who delivered between January 2021 and June 2023 and recorded ≥2 daily BP measurements using a RBPM cuff after an HDP diagnosis. HDP subtypes included gestational hypertension, preeclampsia, and de novo postpartum hypertension detected during the delivery hospitalization; patients with chronic hypertension were excluded. Hypertension resolution was defined as ≥2 consecutive days of normal BP (systolic BP 2 weeks to reach hypertension resolution. Less stringent definitions of resolution may misclassify patients as normotensive, emphasizing the need for longer-term BP monitoring.
Mujic et al. (Tue,) conducted a cohort in Hypertensive disorders of pregnancy (HDP) (n=1,773). Remote blood pressure monitoring (RBPM) was evaluated on Hypertension resolution (≥2 consecutive days of normal BP without antihypertensive medication use). Among patients with hypertensive disorders of pregnancy using remote blood pressure monitoring, 31.5% achieved hypertension resolution within 6 weeks, taking an average of 15.0 days.
