The association of serum potassium level with left ventricular mass in patients with primary aldosteronism

Eur J Clin Invest 2011; 41 (7): 743–750 Abstract Background Primary aldosteronism (PA) is associated a worse cardiovascular outcome than essential hypertension. Hypokalemia, which is one major characteristic of PA, can affect both cardiac structure and function. The goal of this study is to evaluate the influence of serum potassium level on left ventricular (LV) mass and function in PA patients. Materials and methods We prospectively analysed 85 PA patients from October 2006 to September 2008 and 27 essential hypertension patients as the control group (group 1). Thirty-two patients with serum potassium
