Hypertensive Disorders of Pregnancy

Abstract

Purpose of review: Although pregnancy-related deaths are rare in the USA, they are on the rise and have more than doubled in the last 20 years. A substantial portion of these deaths are related to cardiovascular disease, specifically hypertensive disorders of pregnancy (HDP). In this review, we will discuss the definitions and proposed pathophysiology of HDP as well as its potential role in cardiovascular morbidity and mortality.

Recent findings: Placental hypoperfusion may lead to an imbalance in proangiogenic and antiangiogenic factors, notably an increase in soluble fms-like tyrosine kinsase-1 (sFlt-1), thereby leading to endothelial dysfunction. Progress has been made in terms of determining the factors which lead to preeclampsia. Potential novel biomarkers for predicting preeclampsia risk have been identified through this research. Preeclampsia not only has important implications for the health during pregnancy but also for future cardiovascular risk. However, the exact mechanism by which it increases cardiovascular risk and the degree of risk it portends are yet to be elucidated.
