Racial disparities exist among the population of individuals who use aspirin as a primary prevention for coronary heart disease (CHD). In 2000-2002, aspirin use among those at an increased risk of CHD was 25% among Caucasians, 14% among African Americans, 12% among Hispanics, and 14% among Chinese. After new guidelines for the use of aspirin to prevent CHD were established in 2002, the racial disparities still persisted. Regardless of race, the overall use of aspirin among all populations are low.
