Guidelines for treating heart failure.

Optimal guideline-directed medical therapy for heart failure with reduced ejection fraction comprises the angiotensin receptor-neprilysin inhibitor (sacubitril/valsartan), an evidence-based beta-blocker (bisoprolol, carvedilol, or sustained-release metoprolol), a mineralocorticoid antagonist (spironolactone or eplerenone), and a sodium-glucose cotransporter-2 inhibitor (dapagliflozin or empagliflozin). Optimal guideline-directed medical therapy for heart failure with preserved ejection fraction comprises a sodium-glucose cotransporter-2 inhibitor with emerging evidence to support the use of a mineralocorticoid antagonist and glucagon-like peptide-1 receptor agonists. This review will summarize the evidence behind the guideline recommendations, the impact of newer trials on management of patients with HF, and strategies for implementation into clinical practice.
