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.
In Part 1 of this two-part series, we dissected the evidence behind the use of MRAs in HFrEF, HFpEF and MI to further understand the reasons for their underutilization and alleviate some of those concerns. In Part 2, the use of MRAs in resistant hypertension will be discussed, as well as considerations regarding blood pressure, potassium, and renal effects given these may play key roles in precluding MRA use when warranted.
Mineralocorticoid receptor antagonists are arguably one of the most underutilized medication classes despite sound evidence supporting their use across a spectrum of cardiovascular diseases. Part 1 of this two-part series chronicles current evidence evaluating the use of MRAs, particularly spironolactone, in the treatment of heart failure (both chronic and acute settings) and myocardial infarction.
