Possible Common Aetiology behind Maternal Preeclampsia and Congenital Heart Defects in the Child: a Cardiovascular Diseases in Norway Project Study
The aetiology of congenital heart defects (CHD) is mostly unknown, but maternal factors may modify the infant risk of CHD. We investigated the association between maternal preeclampsia and offspring risk of severe CHD in a nation-wide cohort study. Information on all births registered in the Medical Birth Registry of Norway, 1994-2009, was completed with information on CHD diagnoses from national health registries and the Cardiovascular Diseases in Norway Project (CVDNOR). Among 914 703 singleton births without chromosomal abnormalities, 32 864 (3.6%) were born after a pregnancy with preeclampsia. The preeclampsia was diagnosed before the 34th week of pregnancy (early-onset preeclampsia) in 2618 (8.0% of preeclamptic pregnancies). CHDs were diagnosed in 10 691 infants; of these, 2473 had severe CHD. The risk of severe CHD was compared between births with and without maternal preeclampsia and estimated with binomial log-linear regression. When adjusting for year of birth, maternal age, parity, and pregestational diabetes, the risk ratio (RR) for severe CHD in offspring of mothers with any preeclampsia was 1.3 [95% confidence interval (CI) 1.1, 1.5], and in pregnancies with early-onset preeclampsia, the RR was 2.8 (95% CI 1.8, 4.4). The association between early-onset preeclampsia and specific types of severe CHD was stronger for atrioventricular septal defects (AVSD), with adjusted RR 13.5 (95% CI 6.8, 26.8). Early-onset preeclampsia was strongly associated with infant risk of severe CHD, specifically; the risk of AVSD was 15-fold higher if the mother was diagnosed with early-onset preeclampsia, suggesting common aetiological factors for early-onset preeclampsia and erroneous fetal heart development..
