Altered hemodynamics and hyperuricemia accompany an elevated sFlt-1/PlGF ratio before the onset of early severe preeclampsia.Doherty, Anne; Carvalho, Jose C A; Drewlo, Sascha; El-Khuffash, Afif; Downey, Kristi; Dodds, Madelaine; Kingdom, John; Department of Anesthesia, Mount Sinai Hospital, University of Toronto, Toronto ON. (2014-08)Early identification of women at risk of developing early-onset severe preeclampsia (sPE) is a key objective in obstetrics. An elevated ratio of serum soluble fms-like tyrosine kinase (sFlt-1) to placenta-like growth factor (PlGF) (sFlt-1/PlGF ratio) precedes overt hypertension. The longitudinal relationship between this biomarker, maternal hemodynamics, and maternal serum uric acid during the pre-clinical phase is unknown.
