RESUMO
OBJECTIVE: This study sought to determine whether preeclampsia; gestational diabetes; and adverse obstetrical outcomes such as placental abruption, intrauterine growth restriction, and preterm delivery are independent risk factors for cardiovascular disease later in life. METHODS: This was a retrospective, age-matched, case-control study that surveyed 244 cases (women with confirmed coronary artery disease) and 246 controls (women who did not have coronary artery disease) on their obstetrical history and outcomes, as well as traditional cardiovascular risk factors. Analyses were performed using SAS software version 9.1.3. (Canadian Task Force Classification II-2). RESULTS: Women with coronary artery disease had significantly higher rates of maternal complications such as gestational hypertension (odds ratio [OR] 3.34; 95% confidence interval [CI] 1.03-10.9), as well as conventional vascular risk factors such as dyslipidemia (OR 5.38; 95% CI 2.70-10.7), hypertension (OR 2.40; 95% CI 1.23-4.70), diabetes (OR 2.32; 95% CI 1.07-5.01), and smoking (current smoker: OR; 4.82 95% CI 1.66-14.00; former smoker: OR 2.86; 95% CI 1.43-5.71). There were more cases with preeclampsia (9.8%, vs. 5.4% in controls); however, the difference was not statistically significant. CONCLUSION: Among the adverse maternal conditions, there was more gestational hypertension in women with coronary artery disease. In this study, hypertensive disorders of pregnancy were the most important maternal risk factors for cardiovascular disease later in life and should be flagged early for close monitoring and/or intervention.
