- * Two major or one major and two minor criteria. BNP = brain natriuretic peptide; LCI = lung-cardiac-inferior vena cava; AHFS = acute heart failure syndromes; NPV = negative predictive value; PPV = positive predictive value; LVEF = left ventricular ejection fraction; IVC = inferior vena cava; MR = mitral regurgitation; TR = tricuspid regurgitation.
