INTRODUCTION<br />

The leading cause of mortality in both men <strong>and</strong><br />

women in the United States is cardiovascular<br />

disease (CVD) due to atherosclerosis.<br />

Atherosclerosis involves chronic inflammation <strong>and</strong> a<br />

progressive buildup of lipids <strong>and</strong> fibrous elements<br />

in the arterial walls. It begins with the formation<br />

of “fatty streaks”. Fatty streaks can be found in<br />

the aorta by 10 years of age, in the coronary<br />

arteries by age 20, <strong>and</strong> in the cerebral<br />

vasculature by the age of 40. 1<br />

Early intervention<br />

is imperative. Preventive interventions focused on<br />

managing cholesterol, blood pressure, <strong>and</strong> weight,<br />

have been found to favorably alter atherosclerotic<br />

progression. Unfortunately, less that 50% of the<br />

cardiovascular events are prevented in the<br />

treatment groups of the most successful clinical<br />

trials. 1,2<br />

In fact, most myocardial infarctions (MI)<br />

occur in individuals with normal cholesterol levels. 3<br />

Greater focus on contributing factors (i.e.,<br />

inflammation) involved in the atherosclerotic<br />

disease process may be helpful in preventing<br />

cardiovascular events.<br />

Biological data now demonstrate that most MIs<br />

occur after atherosclerotic plaque rupture <strong>and</strong><br />

thrombosis (clot) formation. Inflammation can<br />

threaten plaque stability <strong>and</strong> increase its propensity<br />

to rupture <strong>and</strong> in turn cause thromboses that<br />

trigger a cardiovascular event. Approximately twothirds<br />

to three quarters of all fatal coronary<br />

thromboses are due to rupture of the fibrous cap. 4<br />

Autopsies show that rupture is more likely to<br />

occur in plaques with a soft lipid core <strong>and</strong> a thin<br />

inflamed fibrous cap. 5 Therefore, the contributing<br />

factors that lead to the lipid core <strong>and</strong> inflamed<br />

cap need to be addressed in an intervention.<br />

Nutrition therapy can play an integral role in the<br />

prevention of atherosclerosis <strong>and</strong> should aim to<br />
