Description

The “Pregnancy Adaptation” research team led by Dr. Hubel is currently funded by the American Heart Association as a Center within the Go Red For Women Strategically Focused Research Network (SFRN). The theme of the overall Center is “Women’s Cardiovascular Health and Microvascular Mechanisms: Novel Insights from Pregnancy”. Women with adverse pregnancy outcomes, including preeclampsia, preterm delivery or intrauterine growth restriction, have a significantly (2- to 8-fold) increased risk of hypertension, coronary artery disease or stroke in the years after delivery. Pregnancy is thus a natural “stress test” that may reveal risk of later CVD. The Magee Go Red Center posits that individual differences in a woman’s cardiovascular and metabolic (cardiometabolic) response to the challenge of pregnancy can provide valuable and unique information about her future health and, further, that this information can be utilized to delineate differing trajectories over the ensuing decades, be that continued freedom from CVD or accelerating cardiometabolic dysfunction. Here an important goal is to identify mechanisms of later life CVD in women that are unmasked by pregnancy phenotype including maladaptive vascular responses to pregnancy and placental pathology. In addition to his role as center Director, Dr. Hubel is also PI of the Clinical Project, “Glycocalyx Pathways Linking Pregnancy Profile with Microvascular Dysfunction Postpartum”. In this context, his clinical team is testing the hypothesis that damage to the vascular endothelial glycocalyx (endothelial surface layer) underlies development of both the maternal manifestations of preeclampsia and later-life CVD, and thus is a potential target for therapy.
