Table 1: Diagnostic Requirements for Heart Failure According to the European Society of Cardiology 2012 Guidelines.

The diagnosis of HF-REF requires three conditions to be satisfied:

1. Symptoms typical of HF

2. Signs typical of HF^a

3. Reduced LVEF

The diagnosis of HF-PEF requires four conditions to be satisfied:

1. Symptoms typical of HF

2. Signs typical of HP^a

3. Normal or only mildly reduced LVEF and LV not dilated

4. Relevant structural heart disease (LV hypertrophy/LA enlargement) and/or diastolic dysfunction

HF = heart failure; HF-PEF = heart failure with ‘preserved’ ejection fraction; HF-REF = heart failure and a reduced ejection fraction; LA = left atrial; LV = left ventricular; LVEF = left ventricular ejection fraction. ^aSigns may not be present in the early stages of HF (especially in HF-PEF) and in patients treated with diuretics.
