BACKGROUND AND AIM: Dividing patients with heart failure (HF) based solely on ejection fraction (EF) may over simplify the hemodynamic states of these patients. We describe a novel echo-derived hemodynamic HF model based on flow (stroke volume index [SVI]) and left atrial pressure (E:E') correlates.

METHODS: A retrospective analysis of patients admitted with HF with both reduced (HFrEF) and preserved EF (HFpEF). Patients were subdivided into four hemodynamic groups based on echocardiographic SVI (< or ≥35 mL/m

RESULTS: A total of 176 patients were enrolled, 123 patients had HFrEF and 53 patients had HFpEF. Baseline characteristics were not statistically significant in both groups. In HFrEF, most patients were in group D compared to a heterogeneous distribution in HFpEF (P

CONCLUSIONS: Hemodynamic subgroups differ between HFrEF and HFpEF. There is no difference in major adverse cardiovascular events between both groups with increased readmissions in HPpEF patients. Larger studies may help assess the impact of echo-derived hemodynamic state on clinical outcome.
