  1. Maryland ACEP Chapter Educational Conference & Annual Meeting March 12, 2020 FACULTY: Tiffany C. Fong, MD, FACEP PRESENTATION HFrEF, HFpEF, what the (EF)? Point-of-Care Echo in the Evaluation of Heart Failure DESCRIPTION Decompensated heart failure is a commonly encountered clinical syndrome in the emergency department. Though emergency care providers have significant comfort with the diagnosis and management of patients with reduced ejection fraction, heart failure with preserved ejection fraction can be more enigmatic. This talk will provide an overview of the relevant pathophysiology, point-of-care echo findings, and management of HFrEF and HFpEF. OBJECTIVES • Recognize the clinical syndromes of heart failure with reduced and preserved ejection fraction (HFrEF and HFpEF). • Describe multiple techniques to estimate ejection fraction on point-of-care echocardiography. • Explain the basic physiology of left ventricular diastole. • Identify key sonographic findings in HFpEF. • Describe the management strategies for HFrEF and HFpEF. DISCLOSURE No significant financial relationships to disclose.
