IntroductionTo investigate the ability of cardiovascular plasma biomarkers to identify imminent preeclampsia (PE) among pregnant women at triage.Material And MethodsC-terminal pro-arginine vasopressin (copeptin), C-terminal pro-endothelin-1 (CT-proET-1), mid-regional pro-adrenomedullin (MR-proADM), and mid-regional pro-atrial natriuretic peptide (MR-proANP) were prospectively measured in pregnant women presenting at the obstetrical triage units of the University Hospitals of Basel and Zurich, Switzerland. Logistic regression and receiver operating characteristics (ROC) analysis was used to assess and quantify the predictive ability of cardiovascular biomarkers.ResultsOf the 147 included women, 27 (18.4%) were diagnosed at admission with PE. All biomarker levels were significantly higher in participants with PE as compared to controls. However, only MR-proANP, MR-proADM and CT-proET-1 were significant and independent predictors of PE, after taking into account the effect of various clinical confounders. The area under the ROC curve (AUC) was 0.62 (95% confidence interval 0.50-0.73) for copeptin, 0.64 (0.52-0.76) for MR-proADM, 0.71 (0.61-0.82) for CT-proET-1, and 0.83 (0.73-0.92) for MR-proANP. The combination of MR-proANP and MR-proADM resulted in the highest diagnostic performance (AUC 0.88; 0.79-0.96).DiscussionAssessment of the cardiovascular plasma biomarkers MR-proANP and MR-proADM holds promise to support diagnosis of PE at triage.
