XXXX and long-term maternal @entity65 mortality: a population-based registry study in Norway and Sweden.

UNASSIGNED: @entity1 with preeclamptic pregnancies have increased long-term @entity65 ( @entity65 ) mortality. We explored this mortality risk among @entity1 with @entity5869 , another placental pathology. We used linked Medical Birth Registry and Death Registry data to study @entity65 mortality among over two million @entity1 with a first singleton birth between 1967 and 2002 in Norway and 1973 and 2003 in Sweden. @entity1 were followed through 2009 and 2010, respectively, to ascertain subsequent pregnancies and mortality. Cox regression analysis was used to estimate associations between @entity5869 and cardiovascular mortality adjusting for maternal age, education, year of the pregnancy and country. There were 49,944 @entity204 after an average follow-up of 23  years, of which 5453 were due to @entity65 . @entity1 with @entity5869 in first pregnancy (n  =  10,981) had an increased risk of @entity65 (hazard ratio 1.8; 95  % confidence interval 1.3, 2.4). Results were essentially unchanged by excluding @entity1 with pregestational @entity101 , @entity1468 or @entity6 . @entity1 with @entity5869 in any pregnancy (n  =  23,529) also had a 1.8-fold increased risk of @entity65 mortality (95  % confidence interval 1.5, 2.2) compared with @entity1 who never experienced the condition. Our findings provide evidence that @entity5869 , like other placental complications of pregnancy, is associated with @entity1 's increased risk of later @entity65 mortality.
