The recent PRAECIS (Preeclampsia Risk Assessment: Evaluation of Cut-offs to Improve Stratification) study, the largest prospective USA study to date that included 31% Black and 16% Hispanic women, identified and validated an sFlt-1:PlGF ratio to aid in the risk stratification of pregnant women (>18 years of age between 23 weeks 0 days and 34 weeks 6 days’ gestation) hospitalized for hypertensive disorders (preeclampsia, chronic hypertension with or without superimposed preeclampsia, or gestational hypertension) for developing PE-SF59 (See Table 1). Here, PGF is linked to hypertensive disorder.
