Description

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.
