Values are presented as percentages, except when indicated. SD: standard deviation; BMI: body mass index; IQR: interquartile range; LVEF: left ventricle ejection fraction; NYHA: New York Heart Association; COPD: chronic obstructive pulmonary disease; PASP: pulmonary arterial systolic pressure; TSH: thyroid-stimulating hormone; T4: thyroxine; eGFR: estimated glomerular filtration rate; BNP: B-type natriuretic peptide.
