Abstract 10110: Sex and Ethnic/Racial Disparities in Ischemic Heart Disease Related Mortality Rates Among Older Adults

Abstract

Introduction: Ischemic heart disease (IHD) accounts for significant morbidity and mortality in the elderly population. The aim of this study was to examine the trends in IHD related deaths in elderly population in the United States from 1999 to 2019. Methods: We used CDC Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) to access National Vital Statistics System data from 1999 to 2019. IHD related deaths, age >/=75 years were identified from multiple causes of death and were represented as age-adjusted mortality rates (AAMR) per 10,000 population. Joinpoint regression was used to examine changes in trend and annual percentage change (APC) overall and stratified by sex and racial/ethnic groups. Results: AAMR related to IHD decreased from 271.9 in 1999 to 137.3 in 2019 (average APC-3.4[95% CI, -3.7 to -3.0]). AAMR was higher in men (241.3) than women (156.9). Among the racial/ethnic groups, AAMR was highest in non-Hispanic whites (NHWs) (195.1) followed by non-Hispanic blacks (NHBs) (185.6), non-Hispanics American Indian or Alaska Natives (NH-AIAN) (152.7), Hispanics (147.4), and lastly non-Hispanics Asian or Pacific Islanders (NH-APIs) (110.5). AAMR was highest in NHW males (250.6). APC in AAMR decreased across all the subgroups. After initial decline, the decrease in APC in AAMR decelerated in both women (-2.7) and men (-2.0) since 2014, NHBs (-2.4) since 2014, Hispanics (-2.9) since 2012 and NH-API (-2.2) since 2015. After initial decline, AAMR remained stable in NHWs (APC -1.5) since 2016. After initially remaining stable, AAMR decreased in NH-AIAN (APC -3.3) since 2004. Conclusion: IHD related mortality in elderly has been decreasing at a variable pace across various sex and racial/ethnic groups. The causes of these disparities need to be examined and targeted interventions are required to address these disparities.
