H2FPEF_Score_for_Heart_Failure_with_Preserved_Ejection_Fraction v.1
Estimates probability of underlying heart failure in patients with preserved ejection fraction on echo.
To calculate H2FPEF Score and thereby, estimate the probability of underlying heart failure in patients with preserved ejection fraction on echo.
Use in euvolemic patients with unexplained exertional dyspnea who have had an echo, to assess for heart failure with preserved ejection fraction (HFpEF). HFpEF is difficult to diagnose, and historical diagnostic criteria have been consensus-based. This score offers an evidence-based way to identify patients likely to have HFpEF. Probability of heart failure with preserved EF = (Z / (1 + Z)) x 100 where Z = e^y where, y = -9.1917 + 0.0451 x age + 0.1307 x BMI + 0.0859 x E/e' ratio + 0.0520 x pulmonary artery systolic pressure + 1.6997 x atrial fibrillation (1 for Yes and 0 for No).
