Abstract
Background—The present study aimed to assess use of lipid-lowering medication at discharge in a current national sample of patients hospitalized with acute myocardial infarction and to evaluate factors associated with prescribing patterns. Methods and Results—Demographic, procedural, and discharge medication data were collected from 138 001 patients with acute myocardial infarction discharged from 1470 US hospitals participating in the National Registry of Myocardial Infarction 3 from July 1998 to June 1999. Lipid-lowering medications were part of the discharge regimen in 31.7%. Among patients with prior history of CAD, revascularization, or diabetes, less than one half of the patients were discharged on treatment. In multivariate analysis, factors independently related to lipid-lowering use included history of hypercholesterolemia (odds ratio [OR] 4.93; 95% CI 4.79 to 5.07), cardiac catheterization during hospitalization (OR 1.29; 95% CI 1.24 to 1.34), care provided at a teaching hospital, (OR 1.26; 95% ...
