diastolic heart failure
Last edited 11/2019 and last reviewed 06/2023
Heart failure with preserved ejection fraction is estimated to constitute up to half of heart failure diagnoses worldwide (1)
- originally thought to represent the clinical manifestations of diastolic
dysfunction (with the terms often used interchangeably)
- now clear that there are diverse pathological factors at work and even more diverse aetiologies behind this
HFpEF (Heart Failure with preserved Ejection Fraction) diagnosis:
- The American Heart Association (1) and European Society of cardiology (2) are broadly in agreement with their definitions of HFpEF as representing patients with signs and symptoms of heart failure, evidence of normal or preserved ejection fraction but objective evidence of other structural or functional alterations in cardiac structure
- ESC guidelines are more descriptive in terms of specifying particular markers of diastolic dysfunction and also taking into account stress testing, although both emphasize the importance of ruling out noncardiac causes of symptoms.
AHA criteria:
Notes:
- heart failure with a normal ejection fraction (HFNEF)
- according to population based epidemiology prevalence studies, a normal
left ventricular ejection fraction was observed in nearly 50% of patients
with HF symptoms (3). This is also known as heart failure with preserved
ejection fraction (HFPEF). Some claim that HFNEF/HFPEF is synonymous with
diastolic HF although this is controversial since:
- there is no universally accepted definition or agreed detection methods for diastolic HF (3)
- evidence point out that in these patients, the physiological abnormalities are not restricted to diastole only since there is an undetected impairment of systolic function as well (3,4)
