title: OS104. Are preeclampsia and adverse obstetrical outcomes predictors for longterm cardiovascular disease?
abstract: BACKGROUND
  Epidemiologic studies suggest that pregnancy complications such as preeclampsia, gestational diabetes, preterm delivery and low birth weight independently increase maternal risk for future development of cardiovascular disease.
  
  
  OBJECTIVE
  To further investigate whether preeclampsia, gestational diabetes, and adverse obstetrical outcomes such as placental abruption, intrauterine growth restriction and preterm delivery, are independent risk factors for longterm cardiovascular disease.
  
  
  METHODS
  This was a case-control study where 252 parous women (cases) with coronary artery disease were matched with a parous woman within 5 years of age with no known coronary artery disease (controls). Participants were recruited from the Royal Alexandra Hospital in cardiac catheterization lab recovery room in Edmonton, Canada. Women with significant angiographic coronary artery stenosis were eligible as cases and those without were eligible as controls. Participants were interviewed on their pregnancy histories and traditional cardiovascular risk factors, such as hypertension, diabetes etc. Descriptive statistics, chi-square tests and conditional regression analysis were performed.
  
  
  RESULTS
  We recruited 244 cases and 246 controls. The average age was 66.3 and 65.8 respectively. Cases were more likely obese, had more pregnancies as well as traditional cardiovascular risk factors than controls. Adverse pregnancy outcomes were similar between the two groups except gestational hypertension. However, it was not statistically significant in the conditional logistic regression model. Independent risk factors for future cardiovascular diseases were: dyslipidemia (OR 12.8), hypertension (3.0), and being a current (OR 7.4) or former smoker (1.8). Adverse pregnancy outcomes
  
  
  CONCLUSIONS
  In this study, adverse pregnancy outcomes were not independently associated with cardiovascular disorders. Our study was limited by recall bias, and ascertainment of diagnosis.Our study supports that dyslipidemia, hypertensiion and smoking increase future cardiovascular disease. Further studies are needed to examine a postpartum intervention model to proactively manage cardiovascular risk factors, such as lipids, in these at-risk women.
