Design: Secondary analysis of a prospective cohort (nuMoM2b Heart Health Study)
Population: 142 nulliparous women with hypertensive disorder diagnosed before 37 weeks
Primary outcome: Life's Essential 8 health factor score 2–7 years after delivery
Effect: No association with overall score (β −0.26, 95% CI −0.94 to 0.41); non-HDL score β −1.36 (−2.50 to −0.21)

In the nuMoM2b Heart Health follow-up, 142 first-time mothers who developed a hypertensive disorder before 37 weeks were grouped by how long they were managed expectantly before delivery: 2–7 days (30 women) or longer (112, median 17.5 days). Cardiovascular health was measured 2–7 years later.

Longer latency was not associated with a worse overall Life's Essential 8 health factor score. It was associated with slightly worse non-HDL cholesterol scores and slightly higher high-sensitivity CRP, while blood pressure, BMI, HbA1c and NT-proBNP did not differ.

The sample is small and the lipid and CRP findings sit close to the edge of statistical significance, so they are hypotheses rather than a reason to change timing of delivery. What it does usefully remind us is that preterm hypertensive disease marks a woman for long-term cardiovascular follow-up, whichever way delivery timing went. The paper appeared in April 2026.

Expectant management of preterm hypertensive disease was not linked to worse overall cardiovascular health 2–7 years on.
Slightly worse lipid scores and higher CRP were seen after longer latency; treat these as hypotheses.
Do not change delivery timing decisions on this study.
Every woman with a hypertensive disorder of pregnancy should leave with a plan for long-term cardiovascular review.

Why it matters

It eases one worry about expectant management while reinforcing the cardiovascular follow-up many women never get.

The statistics, in plain English

The overall score difference (β −0.26, 95% CI −0.94 to 0.41) crosses zero, so no difference is compatible with the data. The CRP interval (0.001–0.10) only just excludes zero, which is fragile in 142 women. Secondary outcomes like these are more likely to be chance findings than the primary one.
