Table 1. Inclusion and exclusion criteria.

Criteria	Detail
Inclusion criteria	Patients willing and capable of providing informed consent, and who agree to follow the study protocol
	Age >20 years
	Hospitalized patients with acute decompensated HF: the following criteria should be met for the diagnosis of HF:
		1) HF with reduced EF (i.e., EF <40%): presence of the signs and/or symptoms of HF
		2) HF with preserved ejection fraction (i.e., EF ≥40%) requires that all of the following parameters are met: a) presence of the signs and/or symptoms of HF, b) elevated levels of natriuretic peptides (defined as BNP >100 pg/mL and/or NT-proBNP >300 pg/mL), and c) any structural heart disease (left atrial volume index ≥34 mL/m2, left atrial dimension ≥50 mm, posterior or septal wall thickness ≥11 mm)
Exclusion criteria	Any severe condition limiting the life expectancy to <3 months
		1) The patient does not provide permission to be contacted by telephone at the end of the study

HF = heart failure; EF = ejection fraction; BNP = B-type natriuretic peptide; NT-proBNP = N-terminal pro-brain natriuretic peptide.
