This study evaluates the usefulness of Killip classification as a method for early risk stratification of patients with acute myocardial infarction in the 1990s. We followed 1,873 consecutive patients with acute myocardial infarction for 1 year. Higher Killip class was associated with increased in- hospital and 1-year mortality whether or not patients were treated with thrombolytic agents. The overall mortality rate for these patients in the 1990s was found to be lower for each Killip class compared with a comparable patient population hospitalized in the 1980s. Thus, Killip classification continues to be a useful method for early stratification of risk for patients with acute myocardial infarction.
