A pharmacist-led heart failure stewardship initiative for guideline-directed medical therapy in hospitalized patients with reduced ejection fraction.

Background: Heart failure with reduced ejection fraction (HFrEF) is a progressive disease with high rates of hospitalization and mortality. The Canadian Cardiovascular Society recommends treating patients with HFrEF with medications from 4 standard medication classes-this is known as guideline-directed medical therapy (GDMT). However, despite clear evidence and recommendations, GDMT agents are known to be underutilized in the HFrEF population.
