Abstract

Hyperkalemia is a challenging comorbidity to manage in patients with heart failure and chronic kidney disease, particularly when administering renin-angiotensin-aldosterone system inhibitors. We encountered an 88-year-old woman with hypertensive heart failure and chronic kidney disease. A mineralocorticoid receptor antagonist was able to be safely administered despite persistent hyperkalemia when sodium zirconium cyclosilicate, a non-absorbed, non-polymer zirconium silicate compound that preferentially exchanges hydrogen and sodium for potassium and ammonium ions in the gastrointestinal tract, was concomitantly administered. Sodium zirconium cyclosilicate might be a promising therapeutic tool to use in order to administer mineralocorticoid receptor antagonist safely in patients with heart failure, chronic kidney disease, and hyperkalemia.
