Who are Patients Classified Within the New Terminology of Heart Failure from the 2016 ESC Guidelines?

Patients with HFrEF, HFmrEF, and HFpEF share the same cardiovascular risk factors, medical history, and prognosis. Patients with HFmrEF have a different clinical profile, which is nearly the same as patients with HFpEF, except for sex. These results question the relevance of this new classification of HF to stimulate research into this new group of patients.
