Cardiometabolic Consequences of Gestational Dysglycemia

The development of gestational diabetes and even milder forms of dysglycemia during pregnancy represents a maternal phenotype at increased subsequent risk for developing type 2 diabetes mellitus, metabolic syndrome, and, with time, overt cardiovascular disease. A careful and systematic dissection of the hormonal, metabolic, and vascular changes occurring in such women during pregnancy and over the postpartum years provides a unique opportunity to identify conventional and novel conditions and biomarkers whose modification may attenuate adverse long-term outcomes, particularly cardiovascular risk. The purpose of this review is to summarize current understanding of the magnitude of such risk and its potential causes, with a particular focus on postpartum alterations in endothelial and vascular smooth muscle responsiveness.
