This AHA scientific statement provides consensus-driven guidance on the prevention, acute management, and postpartum care of maternal stroke, emphasizing aggressive hypertension management and the safety of standard acute stroke interventions during pregnancy.
Stroke remains a rare but life-threatening complication of pregnancy, with significant implications for both maternal and fetal health. Current stroke prevention and treatment guidelines offer limited guidance for managing stroke in pregnant and postpartum patients. Despite advances in obstetric and neurological care, the diagnosis and management of pregnancy-associated stroke continue to be challenged by delayed recognition, a lack of tailored clinical guidelines, and persistent disparities in outcomes. This scientific statement represents a multidisciplinary effort to synthesize current knowledge of the risk factors and diverse causes of stroke in pregnancy and to offer consensus-driven suggestions for prevention, acute management, and postpartum recovery. Nearly half of all US pregnancy-associated stroke hospitalizations occur in the setting of hypertensive disorders. Primary stroke prevention strategies include risk factor modification, aggressive hypertension management and prompt treatment of severe hypertension in pregnancy and postpartum, and antithrombotic therapy in some high-risk groups. Secondary stroke prevention strategies in pregnancy depend on the mechanism of the prior stroke. Pregnancy should not delay evidence-based treatments for acute stroke. The use of telemedicine can facilitate early consultation with a vascular neurologist and a maternal-fetal medicine specialist in cases of acute pregnancy-related stroke, helping to guide initial decision-making. Computed tomography, computed tomography angiography, and magnetic resonance imaging without contrast are all safe neuroimaging modalities for rapid evaluation of pregnant patients with acute stroke symptoms. Acute stroke alone is not an indication for immediate delivery, and stabilization of the mother should come first. Vaginal delivery after stroke is preferred when feasible because it avoids the surgical risks and hemodynamic stress associated with cesarean delivery. Survivors of pregnancy-associated stroke face unique challenges such as caring for an infant and breastfeeding and require support from a multidisciplinary rehabilitation team. Continued research, including inclusive clinical trials, is urgently needed to refine stroke risk assessment, to expand treatment options, and to improve maternal outcomes.
