Abstract 4138353: Disparities in coronary artery disease-related mortality among patients with obesity in the United States from 1999-2020

Introduction: Coronary artery disease (CAD) is the third leading cause of death in the US for adults aged >35 years. Almost half of the adult US population has obesity, which predisposes to atherosclerosis and may lead to poor prognosis in CAD. We aim to identify CAD-related mortality trends in patients with obesity in the US stratified by age, sex, race, and geographical location. Methods: The CDC-WONDER database was used to extract death certificate data for adults aged ≥25 years. Crude mortality rates (CMR) and age-adjusted mortality rates (AAMRs) per 100,000 persons were calculated, and temporal trends were delineated by calculating annual percent change (APC) and the average APC (AAPC) in the rates using JoinPoint regression analysis. Results: From 1999 to 2020, a total of 182,436 CAD-related deaths occurred in individuals with obesity. The AAMR increased consistently from 1999 to 2018 (APC: 4.48) and surged thereafter till 2020 (APC: 13.91). The AAMR for males (4.91) was almost double that of females (2.76). Non-Hispanic (NH) American Indians or Alaska Natives displayed the highest AAMR (5.37) while NH Asians or Pacific Islanders displayed the lowest (0.88). NH Blacks or African Americans displayed an AAMR of 5.06, followed by NH Whites (3.88) and Hispanics or Latinos (2.6). AAMRs also varied substantially by region (Midwest: 4.09; West: 4; Northeast: 3.67; South: 3.53). States with the highest AAMRs were Vermont and Oklahoma. Non-metropolitan regions exhibited a higher AAMR (4.42) than metropolitan regions (3.64). The adults aged 65-74 years exhibited the greatest CMR (8.99). Conclusion: We observed increasing trends in CAD-related deaths in adults with obesity throughout the study period. The highest mortality was exhibited by males and NH American Indians or Alaska Natives, residents of the Midwest and non-metropolitan areas, and individuals aged 65-74 years. Better healthcare practices and lifestyle modifications should be promoted in these high-risk populations to reduce the CAD-related mortality rates in adults with obesity.
