Impact of Updated Guidelines on Diastolic Dysfunction in Patients with Preserved Ejection Fraction

摘要

Left ventricular (LV) diastolic dysfunction (DD) is regarded as a process of aging in the general population1) and plays a role in progression to heart failure with preserved ejection fraction (HFpEF). Because the past 2009 guidelines for DD used multiple diastolic parameters, these were difficult to apply to various types of cardiac patients. Relatively new 2016 guidelines use fewer parameters, and the classification of DD is easier than with the previous 2009 guidelines. The updated 2016 American Society of Echocardiography/ European Association of Cardiovascular Imaging guidelines committee emphasized the need to simplify the diagnosis and classification of DD in daily clinical practice, and recommended using the most feasible and reproducible parameters of diastolic function and hierarchically organized algorithms.
