Niacin Plus Statin to Prevent Vascular Events

This study has been terminated.
(AIM-HIGH was stopped on the recommendation of the DSMB because of lack of efficacy of niacin in preventing primary outcome events.)

The purpose of this study is to determine whether raising "good cholesterol" with a drug based on the vitamin niacin, while lowering "bad cholesterol" with a statin drug, can prevent more heart disease than the statin alone.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Men and women aged 45 and older with established vascular disease and atherogenic dyslipidemia
  • Established vascular disease defined as one or more of the following: (1) documented coronary artery disease (CAD); (2) documented cerebrovascular or carotid disease; (3) documented symptomatic peripheral arterial disease (PAD)
  • Atherogenic dyslipidemia defined as: (1) LDL-C of less than or equal to 160 mg/dL (4.1 mmol/L); (2) HDL-C of less than or equal to 40 mg/dL (1.0 mmol/L) for men or less than or equal to 50 mg/dL (1.3 mmol/L) for women; (3) TG greater than or equal to 150 mg/dL (1.7 mmol/L) and less than or equal to 400 mg/dL (4.5 mmol/L)
  • For patients entering the trial on a statin: (1) the upper limit for LDL-C is adjusted according to the specific statin and statin dose; (2) HDL-C of less than or equal to 42 mg/dL (1.1 mmol/L) for men or less than or equal to 53 mg/dL (1.4 mmol/L) for women; (3) TG greater than or equal to 125 mg/dL (1.4 mmol/L) and less than or equal to 400 mg/DL (4.5 mmol/L)

Exclusion Criteria:

  • Coronary artery bypass graft (CABG) surgery within 1 year of planned enrollment (run-in phase)
  • Percutaneous coronary intervention (PCI) within 4 weeks of planned enrollment (run-in phase)
  • Hospitalization for acute coronary syndrome and discharge within 4 weeks of planned enrollment (run-in phase)
  • Fasting glucose greater than 180 mg/dL (10 mmol/L) or hemoglobin A1C greater than 9%
  • For patients with diabetes, inability or refusal to use a glucometer for home monitoring of blood glucose
  • Concomitant use of drugs with a high probability of increasing the risk for hepatotoxicity or myopathy, such as those predominantly metabolized by cytochrome P450 system 3A4, including but not limited to cyclosporine, gemfibrozil, fenofibrate, itraconazole, ketoconazole, HIV protease inhibitors, nefazodone, verapamil, amiodarone; lipid-lowering drugs (other than the investigational drugs) such as statins, bile-acid sequestrants, cholesterol absorption inhibitors (e.g., ezetimibe), fibrates or high-dose, antioxidant vitamins (vitamins C, E, or beta carotene) that can interfere with the HDL-raising effect of niacin
