H2FPEF Score for Heart Failure with Preserved Ejection Fraction

Probability that unexplained exertional dyspnoea represents HFpEF.

H2FPEF Score for Heart Failure with Preserved Ejection Fraction
Body mass index >30 kg/m2 (Heavy)
>=2 antihypertensive medications (Hypertensive)
Atrial fibrillation (paroxysmal or persistent)
Echo pulmonary artery systolic pressure >35 mmHg (Pulmonary hypertension)
Age >60 years (Elder)
Echo E/e' ratio >9 (Filling pressure)
Result0 points

Low probability of HFpEF.

Probability category
Low probability

When to use

  • Evaluating unexplained exertional dyspnoea with a preserved ejection fraction to estimate the likelihood of HFpEF before invasive testing.

Formula

Weighted additive score (0-9): atrial fibrillation = 3, obesity (BMI >30) = 2, age >60 / >=2 antihypertensives / E/e' >9 / PASP >35 mmHg = 1 each. Score 0-1 = low, 2-5 = intermediate, 6-9 = high probability of HFpEF.

Pearls and pitfalls

  • Derived against invasive exercise haemodynamics as the reference standard, outperforming prior expert-consensus algorithms.
  • Intermediate scores (2-5) benefit most from further objective testing (exercise echo or invasive catheterisation).
