[Diagnostic Efficiency of Different Screening Indexes for Primary Aldosteronism]

To investigate the the feasibility and diagnostic efficiencyvalue of different screening indexesmethods for screening primary aldosteronism (PA).The clinical data of 499 patients with PA and 479 patients with essential hypertension diagnosed from Jan. 2009 to Dec. 2018 were retrospectively analyzed. The diagnostic performance of different screening indexs was compared by plotting receiver operating characteristic curves (ROC).The area under the ROC curve (For the screening of PA, upright ARR seems to be the best single screening index, while AA2R (radioimmunoassay) is not recommended. The diagnostic efficacy of logistic regression model including upright PAC, PRA and lowest blood potassium is better than that of single upright ARR.
