*Calculated using Cox’s proportional hazards regression.
†Unplanned hospital admission for worsening heart failure only.
Hazard ratios indicate the increased hazard of an event with a doubling of plasma NT-proBNP concentration at time of first presentation.
Hospital admission†16/5514/551.03 (0.79 to 1.35)0.83
All cause mortality without prior hospital admission†3/5514/551.54 (1.08 to 2.19)0.016
