Purpose: Atrial fibrillation is the most common sustained arrhythmia, with a prevalence of 1-2% in the general population and over 15% in people older than 80 years. Due to aging of the population it imposes an increasing burden on the healthcare system because of the need for life-long pharmacological treatment and the associated increased risk of heart failure and hospitalization. Hence, identification of the factors that predispose to atrial fibrillation it is of utmost relevance.
Recent findings: Several conditions exist that are characterized by inappropriately high levels of aldosterone, mostly primary aldosteronism and the severe or drug-resistant forms of arterial hypertension. In these forms, aldosterone can cause prominent target organ damage, mostly in the heart, vasculature, and kidney. This review examines the experimental data and clinical evidences that support a link between hyperaldosteronism and atrial fibrillation, and how this knowledge should lead to a change in our management of the hypertensive patients presenting with atrial fibrillation.
