Association of Global Longitudinal Strain With Clinical Status and Mortality in Patients With Chronic Heart Failure

Importance

Global longitudinal strain (GLS) is an emerging echocardiographic biomarker of cardiac function in heart failure (HF). Evidence from large-scale studies comprehensively investigating GLS for its association with clinical phenotypes and mortality in asymptomatic and symptomatic chronic HF is limited.

Objective

To assess the factors associated with GLS and its prognostic value in patients with chronic HF.
