While the assessment of LV systolic dysfunction has been well investigated by the evaluation of ejection fraction (EF),
diastolic dysfunction characterization is evidently more difficult.
the importance of the assessment of diastolic dysfunction has been increased in last decades,
because is thought to play a crucial role in the pathophysiology of heart failure with preserved ejection fraction (HFpEF),
the previously described “diastolic HF”,
and it has prognostic implications even in the preclinical stage.
diastolic HF is a clinical entity and its diagnosis requires three conditions: the presence of signs or symptoms of HF,
a normal or slightly abnormal LV systolic function (EF >50%),
and the objective evidence of LV diastolic dysfunction.
