New guidelines urge blood pressure control to prevent strokes in pregnancy

Stroke during pregnancy or shortly after childbirth poses a serious risk to both mother and baby. While relatively rare, it remains a leading cause of pregnancy-related deaths each year. New guidance now highlights the importance of early prevention and prompt treatment to reduce these dangers.

Stroke affects around 20 to 40 in every 100,000 pregnancies, making up 4-6% of maternal deaths annually. Certain groups face higher risks, with Black pregnant women twice as likely to experience a stroke compared to white women. Key risk factors include chronic hypertension, pregnancy-related hypertensive disorders, advanced maternal age, diabetes, obesity, and migraines with aura.

Prevention should start before conception, following standard stroke prevention guidelines and promoting healthy habits. Daily low-dose aspirin has been shown to lower preeclampsia risk in high-risk individuals, while better blood pressure management—both during and after pregnancy—can prevent most maternal strokes. Healthcare providers are also urged to recognize stroke symptoms quickly, as pregnancy should never delay urgent treatment.

The new recommendations stress that high blood pressure in pregnancy and postpartum must be managed with medication to avoid complications. Early and aggressive blood pressure control, alongside preventive measures, could significantly reduce stroke cases. Ensuring timely treatment remains critical to protecting maternal and fetal health.
