Killip classification

The Killip classification is used for risk assessment in patients with acute myocardial infarction . People with a low Killip class are less likely to die in the next 30 days.

• Killip Class I - no signs of heart failure .
• Killip class II - fine bubble rattling noises of the lungs, 3rd heart sound or jugular vein congestion.
• Killip Class III - Pulmonary Edema
• Killip Class IV - Cardiogenic shock or pronounced hypotension ( blood pressure below 90 mmHg) and signs of peripheral vasoconstriction ( oliguria , cyanosis ).

The study

The classification was developed from a retrospective evaluation of 250 patients in a cardiological intensive care unit at a university hospital in the USA. It has not been validated on an independent group of patients .

The following results were found:

Killip class I:	81/250 patients	Mortality rate 6%.
Killip class II:	96/250 patients	Mortality rate 17%.
Killip class III:	26/250 patients	Mortality rate 38%.
Killip class IV:	47/250 patients	Mortality rate 81%.

The Killip classification has since played an important role in risk stratification in cardiological studies.
