Background: Screening for primary aldosteronism (PA) using the aldosterone to renin ratio (ARR) is recommended by clinical practice guidelines in patient groups with a high prevalence as the disease is reported by several authors in more than 10% of essential hypertensives (EH).Methods: Plasma aldosterone concentration (PAC) and direct renin (DR) were measured using two novel automated chemiluminescence assays (IDS-iSYS; Boldon, UK) and compared to the S...

Recent studies indicating that normokaliemic primary aldosteronism (PA) is a more frequent cause of hypertension than previously expected led to an increased interest in biochemical screening strategies. We investigated biochemical diagnostic strategies used in different academic centres for patients documented in the German National Conn’s Registry. Data from 7 centres in 5 cities have been entered into a database by trained personnel. For analysis, results from 522 pati...
