Abstract-Because hypertensive pregnancies have been associated with increased cardiovascular disease, we aimed to identify whether angiographically characterized coronary artery disease differed in women with previous normotensive pregnancies or hypertensive pregnancies (HPs Key Words: hypertension in pregnancy Ⅲ preeclampsia Ⅲ coronary artery disease Ⅲ cardiovascular risks Ⅲ coronary angiography I ndirect evidence has linked preeclampsia, other forms of hypertension in pregnancy, and placentation-related defects to cardiovascular (CV) disease later in life. [1][2][3][4][5][6][7][8][9][10][11][12] Although most studies have used registry bases, one includes clinical follow-up, 10 one compares women with angiographically characterized coronary lesions with patients who only underwent clinical screening for coronary disease, 8 and another evaluates coronary calcification, a predictor of coronary artery disease. 11 A prospective study performed in a cohort of women with a precise classification of obstetric outcomes would be necessary to evaluate the tentative association between reproductive and CV complications, but because this is a relatively new finding, any ongoing or new study will need at least a couple of decades to be completed. Furthermore, included subjects would have to be left to the natural evolution of CV disease, and it is ethically inadmissible to abstain from CV preventive management.We decided to take an intermediate stance, by testing whether those subjects who had hypertensive pregnancies (HPs) developed earlier or more extensive coronary lesions than controls who had normotensive pregnancies (NPs). For this purpose, we evaluated the remote obstetric histories in women who underwent coronary angiography, the gold standard for defining coronary disease.
MethodsThis investigation was a case-control observational retrospective study, with the results of coronary angiography as the dependent variable. Women undergoing coronary angiographies because of suspected coronary disease at Hospital Sótero del Río, in the southeast zone of Santiago, Chile, from January 1, 2006, to December 31, 2007, completed a questionnaire (please see the online data supplement at http://hyper.ahajournals.org) to determine their CV risk factors, including the following: family history; age of onset and end of menstrual cycles; hormonal replacement therapy; number of
