Association of multimorbidity with guideline-directed medical therapy intensification in heart failure: Findings from the EPIC-HF trial.

A potential contributor to the suboptimal rates of guideline directed medical therapy (GDMT) prescribing for heart failure with reduced ejection fraction (HFrEF) is the burden of multimorbidity in patients with HFrEF. We examined the effect of multimorbidity on GDMT prescription in the EPIC-HF trial, finding that multimorbidity was associated with decreased likelihood of GDMT intensification. Further study is needed to guide treatment in high-risk, multimorbid patients with HFrEF.
