Title: Collaborative Atorvastatin Diabetes Study (CARDS)


1
Collaborative Atorvastatin Diabetes Study (CARDS)
Atorvastatin 10 mg (n1428)
Patient Population
  • Type 2 diabetes mellitus
  • Men and women 4075 years of age
  • Primary CHD and stroke prevention
  • LDL-C ?160 mg/dL (?4.14 mmol/L)
  • TG ?600 mg/dL (?6.78 mmol/L)
  • ?1 additional RF
  • HTN (or on HTN treatment)
  • Retinopathy
  • Albuminuria
  • Current smoking

2838 patients
4-year follow-up
Double-blind placebo (n1410)
  • Primary endpoint time to first major CV event
    (CHD death, nonfatal MI, unstable angina,
    resuscitated cardiac arrest, coronary
    revascularization, stroke
  • Secondary endpoints total mortality, any CV
    endpoint, lipids, and lipoproteins
