Cardiovascular disease family history and risk of pregnancy loss.


ABSTRACT: PURPOSE:To determine whether family history of cardiovascular disease (CVD) is a risk factor for pregnancy loss, given potential shared etiology, including vascular mechanisms involved in reproduction and placentation. METHODS:In a prospective study, first-degree family histories were self-reported before pregnancy among women with 1-2 previous losses. Women were followed for up to 6 menstrual cycles while attempting pregnancy and through pregnancy. Pregnancies were ascertained by urinary human chorionic gonadotropin and confirmed by ultrasound. Risk ratios and 95% confidence intervals for pregnancy loss were estimated using weighted Poisson regression models with robust standard errors adjusted for covariates including prepregnancy body mass index and sociodemographics. RESULTS:Of 1228 women enrolled, 742 had a clinically confirmed pregnancy, and of these, 18% experienced a clinical pregnancy loss. Forty six percent of women reported family history of CVD, diabetes, hypertension, or hypercholesterolemia/dyslipidemia. Family history of CVD was not associated with the risk of pregnancy loss overall (1.01; 95% confidence interval: 0.64, 1.59) or among women with 2 previous losses (1.05; 0.51, 2.17). Family history of hypertension was also not associated with pregnancy loss (0.98; 0.65, 1.46). CONCLUSIONS:Family history of CVD is not providing additional information helpful in determining the risk of subsequent pregnancy loss in an at-risk group.
