Postpartum Course of Gestational Hypertension and Preeclampsia
Bibliographic record
Abstract
BACKGROUND: New onset hypertension (gestational hypertension and preeclampsia) complicates 6-8% of pregnancies and usually resolves postpartum, but the time to normalization of blood pressure (BP) in the postpartum period is not known. METHODS: We performed a retrospective cohort study of previously normotensive women who developed gestational hypertension or preeclampsia, and determined the number of weeks postpartum to BP normalization. RESULTS: 62 women with no history of hypertension prior to pregnancy were included, age 35.3 +/- 7.1 years. Hypertension developed at gestational age 15-40 weeks; 45% developed hypertension within 3 days of delivery, 52% developed hypertension 1-22 weeks prior to delivery, and 5% had onset only postpartum. Infants were born at gestational age 35.15 +/- 4.7 weeks. Average BP at treatment initiation was 162/95 mm Hg. Preeclampsia and/or HELLP syndrome was diagnosed in 48%. Most were treated with BP medication in the puerperium. In those whose BP normalized, time to normalization was 5.4 +/- 3.7 weeks. Those who remained hypertensive beyond 6 months (19%) were older (38.8 years vs. 34.4, p = 0.018). Three women had secondary hypertension; primary hyperaldosteronism was diagnosed in 2 women and renovascular hypertension in 1. CONCLUSION: Hypertension presenting in pregnancy normalized postpartum in 81% of this cohort, in most by 3 months. Those who remained hypertensive at 6 months postpartum tended to be older than patients whose BP normalized. Secondary hypertension was detected and surgically corrected in 3 patients. Further studies are needed to characterize those most likely to benefit from postpartum antihypertensive treatment and to guide management.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
