Applying the ESC 2016, H2 FPEF, and HFA-PEFF diagnostic algorithms for heart failure with preserved ejection fraction to the general population.

Unexplained dyspnoea is common in the middle-aged general population. The ESC 2016 algorithm and the H2 FPEF and HFA-PEFF scores detect different, discordant subpopulations of probands with breathlessness. Further classification of the HFpEF syndrome is desirable.
