Similar predictive value of six-minute walking distance and B-type natriuretic peptide in heart failure with reduced to mid-range ejection fraction
{{output}}
The prognostic insights of heart failure (HF) with mid-range (40-49%) ejection fraction (HFmrEF) are not fully elucidated. We investigated whether the six-minutes walking test (6MWT) and brain natriuretic peptide (BNP) are predictive of outcome across the spec... ...
