  1. Prediction model includes age, gender, NYHA functional class, left ventricular ejection fraction, and serum BNP levels.
  2. BNP, brain natriuretic peptide; CI, confidence interval; IDI, integrated discrimination improvement; NRI, net reclassification improvement; NYHA, New York Heart Association.
