Heart failure with normal ejection fraction (HFNEF): is it worth considering?

A significant proportion of patients with heart failure happen to have a normal ventricular ejection fraction at echocardiography during examination. Previously called diastolic heart failure, it is nowadays referred to as heart failure with normal ejection fraction (HFNEF) or HF with preserved ejection fraction. The European Society of Cardiology, recognizing the importance of this type of heart failure, recently issued new definition criteria for it. This review will discuss the different steps that lead to such a diagnosis, as well as some new aspects of its pathophysiology. Finally, the management of this form of HF, that is not as straightforward as HF due to systolic dysfunction, will be discussed.
