Use of speckle tracking to assess heart failure with preserved ejection fraction

Abstract

Heart failure with preserved ejection fraction (HFpEF) currently represents approximately 50% of heart failure (HF) cases in the USA and is increasingly recognized as a leading cause of morbidity and mortality. Recent data suggest that the prevalence of HFpEF relative to HF with reduced ejection fraction (HFrEF) is increasing at a rate of 1% per year. With an aging population and increasing risk factors such as hypertension, obesity, and diabetes mellitus, HFpEF will soon be the most prevalent HF phenotype. Two-dimensional speckle-tracking echocardiography (STE) has been used to diagnose HFpEF specifically by focusing on the longitudinal systolic function of the left ventricle (LV). Yet there are many patients with HFpEF in whom there are no differences in LV global longitudinal systolic strain, but there are changes in left atrial function and structure. There are several proposed pathophysiological mechanisms for HFpEF such as endothelial dysfunction, interactions among proteins, signaling pathways, and myocardial bioenergetics. Yet only one specific therapy, mineralocorticoid receptor antagonist, spironolactone, is recommended as a treatment for patients with HFpEF. However, spironolactone does not address many of the pathophysiologic changes that occur in HFpEF, thus new novel therapeutic agents are needed. With the limited available therapies, clinicians should use STE to assess for the presence of this syndrome in their patients to provide effective diagnosis and management.
