  1. Data are presented as the mean ± standard deviation or the number and corresponding percentage (%).*Defined as New York Heart Association functional class III or IV. Defined as requiring treatment with long-term bronchodilators or steroids. Defined and classified according to the highest RIFLE stage throughout the hospitalization. §Inotropic equivalent (mcg/kg/min) = dopamine + dobutamine + 100 × epinephrine + 100 × norepinephrine + 100 × isoprotenolol + 15 × milrinone. AKI, acute kidney injury; APACHE II, acute physiology and chronic health evaluation II score; BMI, body mass index; CAD, coronary arterial disease; CHF, congestive heart failure; CKD, chronic kidney disease; COPD, chronic obstructive pulmonary disease; CPR, cardiopulmonary resuscitation; CVA, cerebral vascular accident; CVP, central venous pressure; ECMO, extracorporeal membrane oxygenation; eGFR, estimated glomerular filtration rate; IABP, intra-aortic balloon pump; MAP, mean arterial pressure; SOFA, sequential organ failure assessment score; TPN, total parenteral nutrition.
