The risks and benefits of spironolactone use in heart failure with a reduced left ventricular ejection fraction and chronic kidney disease

Abstract

Mineralocorticoid receptor antagonists (MRAs) remain underused in cases of heart failure with a reduced left ventricular ejection fraction (HFrEF) and chronic kidney disease (CKD), largely due to the fear of inducing worsening of renal function (RF) and hyperkalemia (HK), particularly in combination with renin angiotensin inhibitors.
