New mothers who experienced hypertension during pregnancy could lower their risk of heart attack, stroke, and even premature death by regularly checking their blood pressure at home, according to new research.
Study Findings
Scientists at the University of Oxford found that women who monitored their blood pressure daily in the weeks after giving birth and had their medication adjusted accordingly had healthier arteries nine months later compared to those receiving standard care. The adjustment of medication based on home readings led to less stiff arteries, which researchers estimate could reduce the future risk of heart attack or stroke by 10%.
Expert Insights
Professor Paul Leeson, who led the study, emphasized that the postpartum period offers a critical window for intervention. “By simply monitoring blood pressure at home, new mothers with hypertensive pregnancies can protect their bodies from future damage,” he said. He hopes the findings will encourage wider use of home monitoring to benefit more women.
High blood pressure conditions like gestational hypertension or pre-eclampsia affect 5-10% of pregnant women and can damage organs and endanger the baby. Long-term risks include a threefold increased likelihood of developing high blood pressure and a doubled risk of heart disease later in life. Harvard research previously linked hypertensive pregnancy to a 42% higher risk of premature death.
Study Details
The Oxford team recruited 220 women with hypertension in pregnancy, all on medication but due to taper off. Of these, 108 received standard care with occasional blood pressure checks, while 112 used a home monitor daily and shared readings via an app with doctors, who adjusted medication as needed. The home-monitoring group achieved better blood pressure control and had less stiff arteries at follow-up six to nine months later. Stiff arteries can exacerbate high blood pressure and lead to clots causing heart attacks and strokes.
Future Implications
Trials are underway to implement blood pressure monitoring after hypertensive pregnancies, with potential NHS specialist clinics delivering the care. Dr. Sonya Babu-Narayan, clinical director at the British Heart Foundation, which funded the research, said the results highlight a crucial postpartum window for protecting women’s heart health. “We now look forward to seeing results from larger studies with longer follow-up to see how this might save women’s lives,” she added, noting the alignment with the renewed women’s health strategy.
