Provided are methods for predicting survival outcome of an individual suffering from congestive heart failure. In accordance with the method, a patient's survival outcome is determined by taking into consideration the levels of two markers in combination, the combination being more predictive of survival than either marker alone. The markers include endothelin, atrial natriurctic peptide and brain natriurctic pcptidc, their precursors and fragments thereof. Individuals with congestive heart failure identified as having increased risk of mortality using the methods of the invention are appropriately targeted for more aggressive therapy.
