Circulating Angiogenic Factor Levels in Hypertensive Disorders of Pregnancy.

Circulating Angiogenic Factor in Hypertension in PregnancyThis study measured serum soluble fms-like tyrosine kinase 1 to placental growth factor values in pregnant women hospitalized with hypertension. In women with a hypertensive disorder of pregnancy presenting between 23 and 35 weeks' gestation, a soluble fms-like tyrosine kinase 1:placental growth factor ratio ≥40 provided stratification of the risk of progressing to severe preeclampsia within 2 weeks.
