The rate of hospitalization for myocardial infarction was examined in the Corpus Christi Heart Project (CCHP), a prospective population-based surveillance program in a biethnic community of Mexican-Americans and non-Hispanic whites. During 12 months of ascertainment, a total of 740 patients hospitalized with definite (217) or possible (523) myocardial infarction were identified. Of the 740 subjects, 334 were Mexican-Americans (150 females and 184 males), 348 were non-Hispanic whites (138 females and 210 males), and 58 were of other ethnic backgrounds. The 1-year age-adjusted rates of hospitalization per 100,000 population were 427.4 and 276.9 among Mexican-American and non-Hispanic white females, respectively, and 721.4 and 502.6 among Mexican-American and non-Hispanic white males, respectively. The age-adjusted hospitalization rate ratios for Mexican-Americans in relation to non-Hispanic whites were 1.55 (95% confidence interval [CI]: 1.23 to 1.95) and 1.40 (95% CI: 1.15 to 1.70) for females and males, respectively. These results suggest that Mexican-Americans may have a greater burden of coronary disease than non-Hispanic whites.
