The Killip classification is a system used in individuals with an acute myocardial infarction (heart attack), taking into account physical examination and the development of heart failure in order to predict and stratify their risk of mortality. 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.
250 patients were included in the study (aged 28 to 94; mean 64, 72% male) with a myocardial infarction. Patients with a cardiac arrest prior to admission were excluded.
Patients were ranked by Killip class in the following way:
Within a 95% confidence interval the patient outcome was as follows:
Mortality rate was found to be 6%.(current 30-day mortality 2.8) |
Mortality rate was found to be 17%.(current 30-day mortality 8.8) |
Mortality rate was found to be 38%.(current 30-day mortality 14.4) |
Mortality rate was found to be 81%. |
Killip class 1 and no evidence of hypotension or bradycardia, in patients presenting with acute coronary syndrome, should be considered for immediate intravenous beta blocker.
