All differences tested using t test, except those noted by footnote symbols.

BMI = body mass index; BNP = brain natriuretic peptide; GFR = glomerular filtration rate; LVEF = left ventricular ejection fraction; NS = not significant; NYHA = New York Heart Association; SBP = systolic blood pressure.

  • Fisher exact test;
