Home blood pressure checks could reduce risks after hypertensive pregnancy

New mothers who experienced hypertension during pregnancy could significantly reduce their risk of future cardiovascular problems by regularly monitoring their blood pressure at home and having their medication adjusted accordingly, according to new research from the University of Oxford. The study involved 220 women who had hypertensive pregnancies and were on blood pressure medication postpartum. Half of the participants used home blood pressure monitors daily and shared their readings with doctors via an app, allowing for timely medication adjustments. This group showed improved arterial function nine months later, with less arterial stiffness compared to those who received routine care, potentially lowering their risk of heart attack or stroke by 10%. Hypertension during pregnancy, including gestational hypertension and pre-eclampsia, affects 5-10% of pregnant women and poses immediate risks to both mother and baby. Beyond childbirth, it substantially increases the likelihood of long-term health issues, with affected women being three times more likely to develop chronic high blood pressure and twice as likely to suffer heart disease. Previous studies have linked hypertensive pregnancy to a 42% increase in premature death risk, highlighting the critical need for effective postpartum management. In the study, women in the standard care group had their medication reduced based on infrequent blood pressure checks over eight weeks postpartum, while those in the intervention group used daily home monitoring to provide continuous data for personalized medication adjustments. This approach resulted in better blood pressure control and improved arterial health, as measured by reduced arterial stiffness, a key factor in cardiovascular risk. The findings underscore the postpartum period as a crucial window for intervention to protect long-term heart health in women with hypertensive pregnancies. Professor Paul Leeson, who led the research, emphasized the importance of this often-overlooked opportunity to safeguard women’s future health. He advocates for wider adoption of home blood pressure monitoring in postpartum care to enable more personalized treatment and reduce the burden of cardiovascular disease among women with a history of hypertensive pregnancy.
