A growing body of evidence supports associations between cardiovascular health and adverse pregnancy outcome and between adverse pregnancy outcome and atherosclerotic cardiovascular disease and builds on the well-established pathways known to exist between cardiovascular health and atherosclerotic cardiovascular disease across the life course and intergenerationally. Furthermore, previous studies frequently lack comprehensive long-term follow-up, making it difficult to assess the enduring impacts of maternal cardiovascular health on postpartum outcomes and long-term maternal and child health.
