The American Heart Association developed the Get With the Guidelines Heart Failure (GWTG-HF) score for predicting mortality in a patient with heart failure. Adherence to approved guidelines should improve patient outcome.
Parameters:
(1) systolic blood pressure on admission
(2) serum BUN in mg/dL on admission
(3) serum sodium in mmol/L on admission
(4) age in years
(5) heart rate in beats per minute on admission
(6) race
(7) COPD

Interpretation:
• minimum score: 0
• maximum score: 101
• The higher the score the greater the risk of in-hospital mortality.
