Abstract

OBJECTIVE—The Treating to New Targets study showed that intensive lipid-lowering therapy with atorvastatin 80 mg/day provides significant clinical benefit beyond that afforded by atorvastatin 10 mg/day in patients with stable coronary heart disease (CHD). The objective of our study was to investigate whether similar benefits of high-dose intensive atorvastatin therapy can be achieved in patients with CHD and diabetes. RESEARCH DESIGN AND METHODS—A total of 1,501 patients with diabetes and CHD, with LDL cholesterol levels of <130 mg/dl, were randomized to double-blind therapy with either atorvastatin 10 (n = 753) or 80 (n = 748) mg/day. Patients were followed for a median of 4.9 years. The primary end point was the time to first major cardiovascular event, defined as death from CHD, nonfatal non–procedure-related myocardial infarction, resuscitated cardiac arrest, or fatal or nonfatal stroke. RESULTS—End-of-treatment mean LDL cholesterol levels were 98.6 mg/dl with atorvastatin 10 mg and 77.0 mg/dl with atorvastatin 80 mg. A primary event occurred in 135 patients (17.9%) receiving atorvastatin 10 mg, compared with 103 patients (13.8%) receiving atorvastatin 80 mg (hazard ratio 0.75 [95% CI 0.58–0.97], P = 0.026). Significant differences between the groups in favor of atorvastatin 80 mg were also observed for time to cerebrovascular event (0.69 [0.48–0.98], P = 0.037) and any cardiovascular event (0.85 [0.73–1.00], P = 0.044). There were no significant differences between the treatment groups in the rates of treatment-related adverse events and persistent elevations in liver enzymes. CONCLUSIONS—Among patients with clinically evident CHD and diabetes, intensive therapy with atorvastatin 80 mg significantly reduced the rate of major cardiovascular events by 25% compared with atorvastatin 10 mg.

  • Subgroup analyses of people with diabetes in larger trials and trials in people with diabetes showed significant primary and secondary prevention of ASCVD events and CHD death in people with diabetes.

    “Subgroup analyses of people with diabetes in larger trials (101-105) and trials in people with diabetes (106,107) showed significant primary and secondary prevention of ASCVD events and CHD death in people with diabetes.”

    From 10. Cardiovascular Disease and Risk Management: Standards of Care in Diabetes—2025 (2025) · cites this paper as [104]

    The Efficacy outcomes section reports a significant reduction in major cardiovascular events among patients with diabetes and established CHD, supporting secondary prevention. It does not study primary prevention, and the reduction in CHD death in the diabetes subgroup was not statistically significant (P = 0.203). (LLM, conf=0.90)

  • Subgroup analyses of people with diabetes in larger trials and trials in people with diabetes showed significant primary and secondary prevention of ASCVD events and CHD death in people with diabetes.

    “Subgroup analyses of people with diabetes in larger trials (94–98) and trials in people with diabetes (99,100) showed significant primary and secondary prevention of ASCVD events and coronary heart disease (CHD) death in people with diabetes.”

    From 10. Cardiovascular Disease and Risk Management: Standards of Care in Diabetes—2026 (2026) · cites this paper as [97]

    The Efficacy outcomes section (page unavailable) reports a significant reduction in major cardiovascular events among patients with diabetes and established CHD, supporting the secondary-prevention portion. This study did not assess primary prevention, and its reduction in CHD death in the diabetes subgroup was not statistically significant (P = 0.203). (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Statins are effective in type 2 diabetes, yet cardiovascular event rates remain high even after statin therapy.

    “Although statins are efficacious in patients with type 2 diabetes, rates of cardiovascular events remain elevated in such patients even after statin treatment.7–9”
  • Lowering low-density lipoprotein cholesterol via statins in type 2 diabetes is effective in reducing the risk of cardiovascular disease.

    “Lipid profile has long been considered among the most important risk factors for CVD in T2DM, and several trials have confirmed that lowering low-density lipoprotein cholesterol (LDL-C) via statins in T2DM was effective in reducing the risk of CVD [81, 82].”
  • A subgroup analysis of 1501 diabetic patients in the TNT study showed a reduction in risk of primary events, cerebrovascular events, and all cardiovascular events in the intensive statin therapy group.

    “A subgroup analysis of 1501 diabetic patients included in the Treating to New Targets (TNT) study, which compared intensive statin therapy (atorvastatin 80 mg) with standard statin therapy (atorvastatin 10 mg), showed a reduction in risk of primary events, cerebrovascular events, and all cardiovascular events in patients in the intensive statin therapy group.442”

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.
