Abstract Background The prognostic importance of the classification ‘heart failure (HF) with mid-range ejection fraction (EF)’ remains uncertain. Objective To analyze the clinical characteristics, comorbidities, complications, and in-hospital and late mortality of patients classified as having HF with mid-range EF (HFmrEF – EF: 40%-49%), and to compare them to those of patients with HF with preserved EF (HFpEF – EF > 50%) and with HF with reduced EF (HFrEF – EF < 40%) on admission for decompensated HF. Methods Ambispective […]

Heart Failure with Preserved Ejection Fraction (HFpEF) Diagnosis Current diagnostic recommendations require evidence of congestion or low cardiac output, considering a combination of clinical information, electrocardiogram, imaging, biomarkers, and, in selected cases, hemodynamic exercise testing. A pretest clinical approach (step 1) followed by a confirmatory score (step 2) is recommended to confirm or rule out the diagnosis of HFpEF. Hemodynamic exercise testing (step 3) is indicated for patients with an intermediate score (). […]
