The primary objective of this study is to determine the degree of additional reduction in cardiovascular risk that was accrued to patients by lowering their LDL-C beyond the currently accepted minimum target level for patients with pre-existing CHD. Secondary objectives include the safety profile of this treatment strategy, its cost-effectiveness, effect on other atherosclerotic-related events and procedures, and total mortality.

  • cardiovascular event, defined as the composite outcome of the
  • following clinical endpoints
  • CHD death
  • Non-fatal/Non-procedure related MI
  • Resuscitated cardiac arrest or fatal/non-fatal stroke

Secondary Outcome Measures:
  • The occurrence of the following clinical events
