Maternal deaths (ie, during pregnancy or <42 days after delivery) have increased in the US in recent years, with 1205 maternal deaths reported in 2021. The resultant maternal mortality rate of 32.9 deaths per 100 000 live births is a significant increase from 20.1 in 2019.1 Additionally, significant disparities exist in maternal mortality, with 2- to 3-fold higher rates among American Indian/Alaska Native and non-Hispanic Black people compared with non-Hispanic White individuals. Approximately 80% of these deaths are preventable, with more than half occurring after delivery, which underscores the postpartum period as a critical time to monitor maternal health. Although the causes of maternal mortality are multifactorial, cardiovascular diseases (CVDs) are a major contributor. The prevalence of poor cardiovascular health (CVH) among individuals prior to pregnancy has increased significantly with less than half of individuals entering pregnancy with favorable CVH.2 Further, adverse pregnancy outcomes (APOs; hypertensive disorders of pregnancy, gestational diabetes, preterm birth, and small-for-gestational age birth) complicate more than 1 in 5 live births in the US, are markers of poor CVH, and are associated with higher lifetime risk of CVD. The first year postpartum provides an opportunity for clinicians to measure, modify, and monitor CVH. Specific recommendations are listed in the Table.
