Poor agreement between different analytical methods measuring aldosterone concentrations impedes applicability of uniform cut-offs in the diagnostic work-up of primary aldosteronism (PA). We compared 4 analytical methods (2 immunoassays and 2 LC-MS/MS) in plasma samples before and after saline infusion test (SIT). 80 hypertensive patients underwent the standardized diagnostic work-up within the German Conn’s registry. Patients (PA n=39/non-PA n=41) were ...

Background: Primary aldosteronism (PA) is a secondary form of arterial hypertension that – in case of unilateral disease – can be cured by surgery. Multiple studies have shown that PA patients are at higher risk to suffer from cardiovascular events and to develop metabolic diseases. Two thirds of patients with PA suffer from obstructive sleep apnea (OSA). A bi-directional, pathophysiological interplay between OSA and PA has been proposed, with focus on overnight ro...

Background: It is known that excessive dietary sodium intake increases cardiovascular risks and contributes to elevated blood pressure. Additionally, a high-salt diet is linked to unfavorable inflammatory immune responses. Notably, individuals with primary aldosteronism (PA) commonly exhibit elevated sodium intake. Despite treatment with mineralocorticoid receptor antagonists (MRA), PA patients do not experience a complete reduction in excess cardiovascular risk compared to hy...
