Asian Americans are the second fastest growing racial/ethnic group in the United States. Our current understanding of Asian American coronary heart disease (CHD) mortality patterns is distorted by the aggregation of distinct subgroups, which masks the heterogeneity of CHD and survival among diverse Asian American subgroups.
We examined CHD mortality rates (ICD-10 codes I20-I25 for ischemic heart disease) from 2003-2009. Proportional mortality ratios (PMRs) were calculated for each sex and ethnic group relative to the non-Hispanic White population. The PMR is the number of observed deaths from a specified cause (CHD) in a defined population (specific Asian subgroup) divided by the number of deaths that would be expected in a referent population (Non-Hispanic Whites). PMRs help to determine the relative importance of CHD as a cause of death in Asian subpopulations.
PMRs for CHD were highest in Asian Indian men (1.47) and women (1.45), followed by Filipino men (1.09) and women (1.10), Chinese women (1.08), and Korean (1.05) women, reflecting a higher CHD mortality burden compared to the NHW referent group. Japanese and Vietnamese men (0.95 and 0.76) and women (0.82 and 0.94), Chinese men (0.95), and Korean men (0.85) all had lower proportionate mortality due to CHD compared to the referent NHW population. PMRs were lower for Black men (0.85) and similar for Black women (1.00) compared to NHWs. When stratified by age group (25-44, 45-64, >65), Filipino men (1.32, 1.05, 1.07) and Asian Indian men (1.40, 1.60, 1.44), had even higher proportions of death due to CHD at younger ages. Asian Indian women (0.65, 1.32, 1.46) demonstrated higher PMRs from CHD with increasing age.
There is significant heterogeneity in CHD mortality patterns among Asian American subgroups, and calls attention to the need for more research to help direct treatment and prevention efforts in an effort to reduce health disparities among diverse communities. Special emphasis should be given to the Asian Indian and Filipino populations given the higher proportions of CHD mortality seen at younger ages.
