Despite its prevalence, there is limited knowledge of BP trends in the postpartum period, hindering opportunities for early detection and timely intervention for dnPPHTN. This study aimed to characterize longitudinal postpartum BP patterns in patients at high risk for dnPPHTN.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n This secondary analysis utilized data from a negative randomized controlled trial (PMID: 38641089) involving 82 normotensive patients at high risk for dnPPHTN, who were randomized to receive either a 5\u2010day course of 20 mg oral furosemide or placebo starting from postpartum day 1. BPs were monitored every 4\u20108 h from delivery to discharge, and subsequently via Bluetooth\u2010enabled remote monitoring twice daily for 6 weeks. The primary goal of this secondary analysis was to characterize distinct patterns of longitudinal BP trajectories in the placebo group. Secondary goals included exploring differences in early postpartum BP trends between those who developed dnPPHTN and those who remained normotensive, as well as identifying the timing of peak BPs. Trends were assessed graphically using local polynomial regression fitting. Linear mixed\u2010effects models were used to examine temporal BP trajectories, including random intercepts and slopes, with an interaction term for the time trend and dnPPHTN diagnosis to explore differential impacts.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 40 participants from the placebo arm of the parent trial were included, contributing a total of 2235 postpartum BP measurements. Both systolic BP (SBP) and diastolic BP (DBP) increased until postpartum days 9 and 12, respectively, before subsequently declining. Significant differences in BP trajectories were observed between participants who developed dnPPHTN (\n n<\/jats:italic>\n \u00a0=\u00a03; 167 BP readings) and those who remained normotensive (\n n<\/jats:italic>\n \u00a0=\u00a037; 2068 BP measurements). Those with dnPPHTN had a significantly steeper rise in SBP preceding the diagnosis, which occurred at a median of 5 days (IQR 5\u20135.5 days). SBP rose by 1.6 mmHg more per day until its peak at postpartum day 9 in those with dnPPHTN, compared to normotensive participants (\n p<\/jats:italic>\n \u00a0<\u00a00.001). DBP rose by 0.3 mmHg more per day and peaked later (postpartum day 14 in those with dnPPHTN vs. day 12 in those who remained normotensive;\n p<\/jats:italic>\n \u00a0<\u00a00.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Using remote monitoring technology, we characterized distinct postpartum BP trajectories in patients at risk for dnPPHTN, revealing a prolonged rise into the second postpartum week and trends that distinguish physiologic from pathophysiologic BP changes. These findings suggest that extended postpartum BP monitoring may be important for timely identification and intervention in patients developing dnPPHTN.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/pmf2.70012","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T12:35:27Z","timestamp":1745498127000},"source":"Crossref","is-referenced-by-count":1,"title":["Characterizing longitudinal blood pressure trajectories in patients at high risk for de novo postpartum hypertension: A randomized controlled trial secondary analysis"],"prefix":"10.1002","volume":"1","author":[{"given":"Ukachi N.","family":"Emeruwa","sequence":"first","affiliation":[{"name":"Division of Maternal\u2010Fetal Medicine, Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Diego School of Medicine, UC San Diego Health La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minhazur R.","family":"Sarker","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Diego School of Medicine, UC San Diego Health La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalie","family":"Bello","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Smidt Heart Institute Cedars\u2010Sinai Medical Center Los Angeles CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marni","family":"Jacobs","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Diego School of Medicine, UC San Diego Health La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louise C.","family":"Laurent","sequence":"additional","affiliation":[{"name":"Division of Maternal\u2010Fetal Medicine, Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Diego School of Medicine, UC San Diego Health La Jolla CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
