Women who have health challenges during pregnancy are at higher risk of subsequent heart problems, and international researchers have found an irregular heartbeat is one of these problems linked to pregnancy challenges. Looking at over 2 million pregnancies in Sweden, the researchers analysed the rate of atrial fibrillation - an irregular and often rapid heart rhythm - among those who had any of six pregnancy complications; preterm delivery, small or large for gestational age, preeclampsia, other blood pressure problems and gestational diabetes. They say all of these problems except small for gestational age were linked to a higher risk of atrial fibrillation in the long term, with some of these links persisting as long as 46 years after pregnancy.

About The Study: In this large national cohort, all adverse pregnancy outcomes except small for gestational age were associated with increased risk for atrial fibrillation up to 46 years later. Women with adverse pregnancy outcomes need early preventive actions and long-term clinical follow-up for timely detection and treatment of cardiovascular disorders related to the development of atrial fibrillation.
