Patient Eligibility for Established and Novel Guideline-Directed Medical Therapies After Acute Heart Failure Hospitalization.

BACKGROUND

Acute heart failure (AHF) hospitalization presents an opportunity to optimize pharmacotherapy to improve outcomes.

OBJECTIVES

This study's aim was to define eligibility for initiation of guideline-directed medical therapy and newer heart failure (HF) agents from recent clinical trials in the AHF population.

METHODS

The authors analyzed patients with an AHF admission within the CAN-HF (Canadian Heart Failure) registry between January 2017 and April 2020. Heart failure with reduced ejection fraction (HFrEF) was defined as left ventricular ejection fraction (LVEF) ≤40% and heart failure with preserved ejection fraction (HFpEF) as LVEF >40%. Eligibility was assessed according to the major society guidelines or enrollment criteria from recent landmark clinical trials.

RESULTS

A total of 809 patients with documented LVEF were discharged alive from hospital: 455 with HFrEF and 354 with HFpEF; of these patients, 284 had a de novo presentation and 525 had chronic HF. In HFrEF patients, eligibility for therapies was 73.6% for angiotensin receptor-neprilysin inhibitors (ARNIs), 94.9% for beta-blockers, 84.4% for mineralocorticoid receptor antagonists (MRAs), 81.1% for sodium-glucose cotransporter-2 (SGLT2) inhibitors, and 15.6% for ivabradine. Additionally, 25.9% and 30.1% met trial criteria for vericiguat and omecamtiv mecarbil, respectively. Overall, 71.6% of patients with HFrEF (75.5% de novo, 69.5% chronic HF) were eligible for foundational quadruple therapy. In the HFpEF population, 37.6% and 59.9% were eligible for ARNIs and SGLT2 inhibitors based on recent trial criteria, respectively.

CONCLUSIONS

The majority of patients admitted with AHF are eligible for foundational quadruple therapy and additional novel medications across a spectrum of HF phenotypes.
