Maternal cardiovascular conditions now surpass hemorrhage and infection as the
leading cause of pregnancy-related deaths in the United States, accounting for
roughly one-third of preventable maternal fatalities. Unfortunately, stark
racial and geographic inequities persist, with Black and Indigenous mothers
dying at two to four times the rate of their White peers. Additionally,
geography affects the risk, with rural residents facing a significantly higher
risk than pregnant patients who deliver in urban centers. The physiologic
changes of pregnancy function as a vascular stress test; therefore, pregnancy
and postpartum offer a critical window of opportunity to identify women with a
high lifetime cardiovascular risk and then to implement prevention strategies.
Evidence-based interventions need to be coupled with coordinated system-wide
changes in primary preventive care in order to mitigate the rising number of
preventable cardiovascular deaths among women in pregnancy and beyond.
Despite evidence of the efficacy of validated screening and prevention
protocols, systemic gaps in maternal care persist. Maternal care deserts are
expanding. In addition, those areas that offer maternal care often lack
sufficient programs that incorporate validated cardiovascular risk-screening
tools and do not maintain dedicated cardio-obstetric care teams. Postpartum
surveillance for blood pressure and cardiac symptoms remains inconsistent, even
though women with hypertensive disorders of pregnancy are nearly four times as
likely to develop chronic hypertension within a year of delivery. Together,
these systemic barriers, including fragmented insurance coverage and maternal
care deserts with limited access even to telehealth, prevent patients from
receiving life-saving essential health care, including cardiac screening and
prevention programs.
Here, we will highlight the differences in federal, state, and hospital-level
policies that contribute to these gaps. Additionally, we will discuss
evidence-based protocols, including standardized safety bundles, remote blood
pressure monitoring programs, and multidisciplinary Cardio-OB clinics, that have
shown promising improvements in maternal cardiovascular outcomes. Finally, we
will propose policy solutions to remove barriers that limit pregnant and
postpartum individuals from accessing antenatal and postpartum care in hopes of
achieving meaningful, lasting reductions in maternal morbidity and mortality.
