Diastolic heart failure (HF) has emerged over the last two decades as a separate clinical entity. Approximately half of the patients presenting with symptoms of congestive HF exhibit a near normal left ventricular (LV) systolic function at rest, which is thought to be caused by a predominant abnormality in diastolic function. It is generally considered to have a somewhat better prognosis than systolic HF, but frequency of hospitalisations is comparable in systolic and diastolic HF.¹ Prevalence of diastolic HF increases with age and is higher in women. It is associated with hypertension, hypertrophy, diabetes, ageing and ischaemia.² Despite the recognition of its importance, definition and diagnostic criteria of diastolic dysfunction and diastolic HF remain controversial.

DEFINITIONS

The cardiac cycle encompasses systole and diastole. Regardless of the exact time limits of these periods, it is generally accepted that systolic function relates with the ability of the ventricle to contract and . . . [Full text of this article]
