Figure. Comparison of H₂FPEF and HFA-PEFF Scores for Diagnosis of Heart Failure With Preserved Ejection Fraction (HFpEF).

H₂FPEF and HFA-PEFF scores of 0 to 1 indicated a low probability of HFpEF; H₂FPEF scores of 6 to 9 and HFA-PEFF scores of 5 to 6 indicated a high probability of HFpEF. Intermediate probability of HFpEF required additional exercise testing for diagnosis. C, The P value is for the difference in area under the curve between scores. ROC indicates receiver operating characteristic.
