Clinical Features and Outcomes of Acute Coronary Syndrome in Women With Previous Pregnancy Complications

摘要

Abstract Background Women with previous cardiometabolic complications of pregnancy experience double the risk of cardiovascular disease. However, few data exist on the clinical effect of these complications at the time of an acute coronary syndrome (ACS). The objective of this work was to compare risk factors, clinical features, and outcomes among women with premature ACS with or without previous pregnancy complications (gestational diabetes and/or hypertensive disorders of pregnancy). Methods Data were obtained from a multicentre cohort of individuals hospitalized with premature ACS. A total of 251 parous women were included and provided obstetric history and blood samples. They were followed for the development of major adverse cardiac events at 12 months. Results At presentation with ACS, women with a previous pregnancy complication (38%) were slightly younger than were women without such complications (47.4 ± 6.2 vs 49.1 ± 5.6 years; P ?= 0.002). They also had more traditional atherosclerotic risk factors. Specifically, women with previous preeclampsia were more likely to have chronic hypertension and an elevated ratio of soluble fms-like tyrosine kinase:placental growth factor. There was no between-group difference in G lobal R egistry of A cute C oronary E vents (GRACE) score or troponin tertile but there was a trend toward higher risk of ST-elevation myocardial infarction in women who had a previous pregnancy complication (odds ratio, 1.80; 95% confidence interval, 1.00-3.23; P ?= 0.05). There was also an increased risk of recurrent ACS at 12 months in women with previous preeclampsia (hazard ratio, 6.79; 95% confidence interval, 1.37-33.63; P ?= 0.02). Conclusions Among a cohort of women with ACS, previous pregnancy complications were associated with more severe disease and poorer outcome.
