Statin Treatment by Low-Density Lipoprotein Cholesterol Levels in Patients With Non–ST-Segment Elevation Myocardial Infarction/Unstable Angina Pectoris (from the CRUSADE Registry)

Elevated low-density lipoprotein cholesterol (LDL-C) is associated with increased risk of myocardial infarction and is a target for disease prevention. The association between initial LDL-C and statin treatment in patients with non–ST-segment elevation myocardial infarction (NSTEMI)/unstable angina pectoris (UAP) has not been well characterized. We explored detailed LDL-C levels and statin treatment in 22,938 patients with NSTEMI/UAP enrolled in the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines Registry (2003 to 2006). Patients reporting home statin use or previous cardiovascular disease were excluded. We examined statin receipt at discharge across 4 categories of baseline LDL-C: very low (
