Microvascular dysfunction: a link between pre‐eclampsia and maternal coronary heart disease

Abstract

Epidemiological studies have recently demonstrated a relationship between pre-eclampsia and coronary heart disease. Insulin resistance has been implicated as a common factor. We have demonstrated, for the first time, using laser Doppler imaging in vivo, impaired microvascular function in women 15-25 years following a pregnancy complicated by pre-eclampsia. Thus, microvascular dysfunction, which is associated with insulin resistance, may be a predisposing vascular mechanism for both coronary heart disease and pre-eclampsia. Pregnancies complicated by pre-eclampsia may identify women at risk of vascular disease in later life and may provide the opportunity for lifestyle and risk factor modification to alter maternal vascular disease risk.
