Abstract
OBJECTIVES: To compare the ophthalmic artery Doppler peak systolic velocity ratio (OA PSV-ratio) and soluble fms-like tyrosine kinase-1/placental growth factor ratio (sFlt-1/PlGF ratio) in predicting adverse maternal and perinatal outcomes in women presenting with new onset hypertension. STUDY DESIGN: Prospective cohort study in a specialist hypertension clinic, within a tertiary referral centre. MAIN OUTCOME MEASURES: Comparison between the OA PSV-ratio and sFlt-1/PlGF ratio in predicting delivery within one week from presentation and adverse maternal and perinatal outcomes e.g. severe hypertension, neonatal unit admission, small for gestational age. RESULTS: Women who delivered within one week, compared to those who did not, had a higher OA PSV-ratio (0.82 vs 0.71, p < 0.01) and sFlt-1/PlGF ratio (93.3 vs 40.5, p = 0.08). Independent predictors of the OA PSV-ratio included mean arterial pressure and maternal weight and predictors of the sFlt-1/PlGF ratio included diastolic blood pressure and use of antihypertensive medications. Prediction of adverse outcomes with both ratios were similar and only modest e.g. AUROC for predicting delivery within one week for OA PSV-ratio was 0.57 (95% CI 0.47-0.67) and for sFlt-1/PlGF ratio was 0.61 (95% CI 0.52-0.70) (p = 0.53). CONCLUSIONS: In women presenting with new onset hypertension, the OA PSV-ratio and sFlt-1/PlGF ratio have similar and modest performance in predicting adverse outcomes.
