Objective: To examine the association of any type of maternal hypertensive disorders of pregnancy (HDP) and neonatal congenital heart diseases (CHD). Study design: We compared the prevalence of CHD between neonates born to mothers with HDP to those delivered to mothers without HDP among 24,525,889 hospital records of living infants, from a national database. We controlled for multiple confounding factors by using multiple logistic regression analysis. Results: Infants delivered to mothers with HDP had higher prevalence of CHD compared to infants born to mothers without HDP [5.20% vs. 1.47%; aOR: 2.51(2.38–2.64), p < 0.001]. Maternal diabetes was more frequent among infants born to mothers with HDP and was independently associated with CHD [aOR 5.14 (5.04–5.23), p < 0.001]. Conclusion: Infants born to mothers with hypertension had almost a threefold increase in CHD compared with those born to mothers without hypertension. Further studies are needed to investigate the underlying mechanism and direction of this association.
