Abstract
BACKGROUND: In the general population, C-reactive protein (CRP) in addition to low-density lipoprotein (LDL) cholesterol level is useful in predicting cardiovascular events. In hemodialysis patients, the additive value is unknown. The association between LDL cholesterol level and outcome previously was suggested to be inverse and confounded by inflammation. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: 1,255 hemodialysis patients with type 2 diabetes mellitus randomly assigned to atorvastatin versus placebo in the German Diabetes Dialysis Study. PREDICTORS: Baseline LDL cholesterol level. OUTCOMES & MEASUREMENTS: Combined vascular end point (cardiac death, myocardial infarction, and stroke), mortality, myocardial infarction, sudden death, and stroke. RESULTS: During 4 years, 465 combined vascular events, 612 deaths, 160 sudden deaths, 200 myocardial infarctions, and 99 strokes occurred. Median LDL cholesterol level was 123 mg/dL. LDL cholesterol level (millimoles per liter and quartiles) was not predictive of outcome. This was analyzed further in patients with and without inflammation. In patients with inflammation (CRP level>5 mg/L), the adjusted relative risk of combined vascular events was 29% greater compared with those without inflammation and a low LDL cholesterol level (LDL cholesterol
