Heart failure may be classified based on the left ventricular ejection fraction.
|
Term |
Also Known As |
|
heart failure with reduced ejection fraction (HFrEF) |
systolic heart failure |
|
heart failure with preserved ejection fraction (HFpEF) |
diastolic heart failure |
Parameters:
(1) current left ventricular ejection fraction (LVEF)
(2) previous left ventricular ejection fraction
|
Current LVEF |
Previous LVEF |

<= 40% |
HFpEF, improved (from HFrEF) |
|
41 to 49% |
> 40% |
HFpEF, borderine |
|

where:
• Several additional categories could be described based on the patterns of current and previous LVEF.
Criteria for HFpEF (see also 06.11.20):
(1) clinical signs and symptoms of heart failure
(2) preserved LVEF
(3) abnormal left ventricular diastolic dysfunction (on cardiac catheterization or Doppler echocardiography)
(4) exclusion of noncardiac causes
Purpose: To classify a patient with heart failure based on left ventricular ejection fraction (LVEF).
Specialty: Cardiology
Objective: imaging studies, laboratory tests, criteria for diagnosis
