Summary

25-30% of women with preexisting vascular disease (chronic hypertension/diabetes/obesity) will develop pre-eclampsia and or growth restriction. In addition, the frequency of stillbirths in this group is dramatically increased over the general population. Pregnancy complications in this very heterogeneous group are likely to be a combination of a failure of the maternal vasculature to adapt to pregnancy and/or a failure of placental development. The relative contribution of these two mechanisms is poorly understood and current preventative strategies (aspirin) in this group only prevent a small number of adverse outcomes. This important and complex group have been inadequately investigated to date mainly because of the diversity of their underlying disease complicating prospective research studies. The evolution of tools which allow more detailed assessments of both uteroplacental blood flow and maternal vascular function will enable us to perform prospective studies in these women and to develop targeted preventative measures. Recent biomarker studies have also identified a number of biomarkers which have not yet been assessed in these high risk groups.
