Observational Study
[Diagnosis of heart failure with preserved or reduced ejection fraction in a one-stop clinic].
a) To assess the usefulness of a one-stop clinic for the diagnosis of outpatients with new onset heart failure; b) to characterize these patients comparing preserved (HF-PEF) versus reduced ejection fraction (HF-REF), and c) to determine brain natriuretic peptide (BNP) cut-off limit to identify HF in outpatients. ⋯ The one-stop HF clinic has diagnosed and characterized outpatients with new onset HF and high prevalence of HF-PEF. The cut-off value of 60.12 pg/ml for BNP provides high sensitivity and specificity to identify HF in this population.
