Echocardiographic parameters differentiating heart failure with preserved ejection fraction from asymptomatic left ventricular diastolic dysfunction.

Background: (LVDD) either remains latent or manifests as heart failure with preserved ejection fraction (HFpEF). Little is known about echocardiographic parameters associated with symptomatic phenotype.

Objective: To investigate echocardiographic parameters associated with symptomatic state in LVDD.
