Novel Potassium-Lowering Agents in Combination with Chronic Heart Failure Therapies

Agents such as patiromer and sodium zirconium cyclosilicate can reduce serum potassium concentrations. But do they have a role in patients with heart failure with reduced ejection fraction (HFrEF)? In this piece, we explore whether these agents could reduce the risk of hyperkalemia when initiating, continuing, or dose-titrating guideline-directed medical therapies in HFrEF.
