Review of progression in diagnosis and treatment of heart failure with preserved ejection fraction

Heart failure with preserved ejection fraction (HFPEF), formerly known as diastolic heart failure or heart failure with normal systolic function, is an increasing health problem. It is characterized by a normal or nearly normal left ventricular ejection fraction compared with HFREF, but with clinical manifestations of heart failure. The 2013 ACCF/AHA Guideline for the Management of Heart Failure has greatly improved the degree of attention to HFPEF. If left ventricular ejection fraction (LVEF) is ≥50%, it is defined as HFPEF. The incidence of this type increases gradually, and prognosis is poorer than for HFREF. However, there are no definite diagnostic standard and treatment methods. This paper mainly summarizes recent research of HFPEF.
