ABSTRACT
OBJECTIVE: Pre-eclampsia is associated with an increased risk of future cardiovascular disease. Maladaptive placentation or malperfusion, as well as predisposing cardiovascular or metabolic risk for endothelial dysfunction, contribute to the systemic inflammatory response that establishes the origins of the disease. The purpose of this study was to investigate the relationship between placental size and cardiovascular risk when assessed at six months postpartum in women who experienced pre-eclampsia.
STUDY DESIGN: Maternal clinical and biochemical cardiovascular risk factors were used to categorize preeclamptic women into high vs. low lifetime cardiovascular disease risk profiles at six months postpartum. A multivariable logistic regression model was then used to identify the association between placental weight to birth weight ratio and high lifetime cardiovascular disease risk, adjusting for maternal age, pre-pregnancy BMI, and severity of pre-eclampsia. A p-value of < 0.05 was deemed statistically significant.
RESULTS: 186/216 women with pre-eclampsia who attended the Maternal Health Clinic met inclusion criteria. No significant differences were observed for placental morphometric measurements between women who screened as having a high vs. low lifetime risk profile for cardiovascular disease at six months postpartum. However, using multivariable modelling that controlled for maternal age, pre-pregnancy body mass index, gestational age at delivery, and severity of pre-eclampsia, a low placenta to birth weight ratio (<15%) was associated with an increased odds of high lifetime cardiovascular disease risk (p < 0.009).
CONCLUSION: The findings of the current study identify clinical measurements that can be collected at the time of delivery which may help identify specific women who may benefit most from postpartum cardiovascular risk screening and intervention.
