Haemodynamics of primary aldosteronism associated with adrenocortical adenoma: Insights from bioimpedance cardiography measurements

Abstract

In mid 1950s, Dr Jerome Conn described a patient with hypertension, and renal potassium wasting associated with adrenocortical adenoma and increased urinary excretion of a sodium-retaining hormone, initially termed electrocortin, which was subsequently shown to be aldosterone. This was the first full report of primary hyperaldosteronism associated with an aldosterone-producing adenoma (APA). It subsequently became apparent that similar abnormalities can occur in the absence of an adrenocortical tumor, and it is now recognized that the APA is just one of many subtypes of primary aldosteronism (PA).
