Relationship of Lipoproteins to Cardiovascular Events: The AIM-HIGH Trial (Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides and Impact on Global Health Outcomes)
This study sought to examine the relationship between niacin treatment, lipoproteins, and cardiovascular (CV) outcomes in this secondary analysis of the AIM-HIGH (Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides and Impact on Global Health Outcomes) trial.Background: During a 3-year follow-up in 3,414 patients with established CV disease and low high-density lipoprotein cholesterol (HDL-C) levels, combined niacin + low-density lipoprotein cholesterol (LDL-C)–lowering therapy did not reduce CV events compared with LDL-C–lowering therapy alone.Methods: Subjects taking simvastatin and/or ezetimibe were randomized to receive extended-release (ER) niacin 1,500 to 2,000 mg or minimal immediate-release niacin (≤150 mg) as placebo at bedtime. LDL-C levels in both groups were maintained from 40 to 80 mg/dl. Hazard ratios were estimated by using Cox proportional hazards models for relationships between lipoproteins and the composite endpoint of CV death, myocardial infarction, acute coronary syndrome, ischemic stroke, or symptom-driven revascularization.Results: CV outcomes were not associated with ER niacin in any baseline lipoprotein tertile. In a subset of patients in both the highest triglyceride (≥198 mg/dl) and lowest HDL-C (
