The Killip classification is a classification system used in individuals with an acute myocardial infarction (heart attack), in order to risk stratify them. Individuals with a low Killip class are less likely to die within the first 30 days after their myocardial infarction than individuals with a high killip class.1
The killip classification
- Killip class I includes individuals with no clinical signs of heart failure.
- Killip class II includes individuals with rales in the lungs, an S3 gallop, and elevated jugular venous pressure.2
- Killip class III describes individuals with frank pulmonary edema.
- Killip class IV describes individuals in cardiogenic shock.
