Redefining primary hyperaldosteronism as “The Syndrome of Inappropriate Aldosterone Secretion (SIALDS)”: A common but unrecognized cause of hypertension

Abstract

Abstract The current screening and diagnostic recommendations for detecting Primary Hyperaldosteronism (PHA) focus on diagnosing the more severe and overt instances of renin‐independent aldosterone production. However, milder forms of autonomous aldosterone secretion have been demonstrated to exist below the diagnostic thresholds of current PHA guidelines, and associate with clinically relevant cardiovascular risk. PHAencompasses a spectrum of renin independent aldosterone production, progressing from a subclinical state in normotensives to a full‐blown clinical syndrome representing the resistant hypertension population. The authors propose the Syndrome of Inappropriately Elevated Aldosterone Secretion (SIALDS) concept as a potential new paradigm for understanding and diagnosing PHA and expanded diagnostic approach to improve early detection even in well‐controlled hypertension. The authors also delve into the impact of treatments, including mineralocorticoid receptor antagonists and emerging aldosterone synthase inhibitors. Furthermore, The authors outline future research directions, proposing clinical trials to investigate the long‐term identification and treatment outcomes of SIALDS.
