What are the different characteristics of HFpEF and HFrEF?

HF could be reduced, midrange or preserved (HFpEF, HFmrEF and HFrEF) HFpEF (dysfunction is diastolic, LVEF >50%, concentric LV remodeling, increased wall thickness and mass with high ratio of mass:volume and no prognostic improvement with HF therapy) HFmrEF (mild systolic and features of diastolic, LVEF 40-49%) HFrEF (dysfunction is systolic, LVEF <40%, eccentric LV remodeling, increased EDV, decreased wall thickness and low mass:volume ratio, and improves with HF therapy (but same mortality)
