Evaluation of 2 Existing Diagnostic Scores for Heart Failure With Preserved Ejection Fraction Against a Comprehensively Phenotyped Cohort.

Classification of the total sample (n=156) according to the HFA-PEFF algorithm (A) and the H 2 FPEF score (B), along with corresponding rates of invasively defined heart failure with preserved ejection fraction (HFpEF inv).
