Summary:

      1. Statement of Problem

           According to the National Fire Protection Association (NFPA), 43.7% of all firefighters
           that died on the job experienced sudden cardiac death. The job also affords an
           incredible amount of stress. Cholesterol therapy has been well demonstrated to reduce
           coronary plaque progression. However is certainly not the only factor in evaluating for
           progression of coronary artery disease (CAD), and other factors must play a role. Garlic
           therapy has been shown to retard atherosclerosis independently.

        2. Hypothesis and Specific Aims The hypothesis of this proposal is: In comparison to the
           placebo group, Aged Garlic Extract (AGE) therapy + Coenzyme Q10 (CoQ10) will be
           effective in slowing progression of coronary artery calcification (CAC) in firefighters
           with established atherosclerosis, independent of baseline blood pressure, statin use or
           other cardiovascular risk factors.

      Specific Aims:

        1. Compare the effects of cholesterol lowering effects in a firefighter population of
           patients under the influence of Aged Garlic Extract + CoQ10 or placebo.

        2. Compare whether degree of change in atherosclerotic coronary artery plaque burden will
           change at a different rate under the influence of Aged Garlic Extract + CoQ10 compared
           to placebo treatment.

        3. Compare whether Aged Garlic Extract + CoQ10 therapy induces changes in baseline values
           including biological and biochemical parameters, such as LDL cholesterol, homocysteine,
           C-reactive protein (CRP), and endothelial function.
