Abstract

Objectives 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 (<33 mg/dl) tertiles, ER niacin showed a trend toward benefit (hazard ratio: 0.74, p = 0.073). In-trial LDL-C levels, non-HDL-C levels, and the total cholesterol/HDL-C ratio were positively associated with CV events in the control group, but these relationships were absent in the ER niacin group. Conclusions Baseline lipoprotein tertiles did not predict differential benefit or harm with ER niacin added to LDL-C-lowering therapy, but a small dyslipidemic subgroup may benefit. ER niacin attenuated expected relationships of lipoprotein risk factors with CV events, raising the possibility that nonlipoprotein actions of niacin could affect risk.

  • Subgroup analyses suggested possible benefits to TG lowering in patients with dyslipidemia.

    The Results section reports a trend toward fewer cardiovascular events with ER niacin in a subgroup with high triglycerides and low HDL-C; the Discussion describes this as possible benefit. The analysis does not establish that triglyceride lowering itself produced the benefit: niacin also raises HDL-C, and the Discussion raises the possibility of nonlipoprotein effects.

  • Randomized data from large outcome studies across broad populations regarding pharmacological TG lowering and effect on CV outcomes have been mixed.

    “However, randomized data from large outcome studies across broad populations regarding pharmacological TG lowering and effect on CV outcomes have been mixed (Table 4).1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24”

    From Rationale and design of <scp>REDUCE‐IT</scp> : Reduction of Cardiovascular Events with Icosapent Ethyl–Intervention Trial (2017) · cites this paper as [5]

    The Introduction (page not provided) reports mixed cardiovascular outcomes across niacin trials: AIM-HIGH and HPS2-THRIVE found no benefit, while earlier trials reported fewer events. The Discussion (page not provided) also notes a possible benefit in a high-triglyceride subgroup and similar findings in fibrate trials. These passages support mixed results for drugs that lower triglycerides, but not the narrower characterization of the evidence as large outcome studies across broad populations specifically testing triglyceride lowering.

  • Any benefits to TG-lowering therapies may be most pronounced among statin-treated patients in the higher range of TG elevation (≥200 mg/dL), for whom randomized prospectively designed outcome studies have not been previously conducted prior to REDUCE-IT.

    “Finally, any benefits to TG‐lowering therapies may be most pronounced among statin‐treated patients in the higher range of TG elevation (ie, ≥200 mg/dL),4, 5, 6 for whom randomized prospectively designed outcome studies have not been previously conducted prior to the REDUCE‐IT study.”

  • Subgroup and post hoc analyses of outcome studies suggest possible reductions in major CV events with TG-lowering therapy.

    “Furthermore, TG reduction lowers several inflammatory markers associated with CV risk, and subgroup and post hoc analyses of outcome studies suggest possible reductions in major CV events with TG‐lowering therapy.3, 4, 5, 6, 7, 8, 9, 10, 11”
  • The subgroup data from ACCORD Lipid, AIM-HIGH, and JELIS trials further support a prospective study of EPA in a broader patient population with hypertriglyceridemia, as a potential add-on to statin therapy to reduce residual CV risk.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
