Abstract 4147150: <u>Geographic, Gender,&amp;Racial Trends in Mortality Due to Coronary Artery Disease in Hypertensive Adults Aged 25 and Older in the United States, 1999-2020: A CDC WONDER Database Analysis</u>

Background: Coronary artery disease (CAD) in patients with hypertension is a significant health concern among adults in the United States. This study investigates trends and demographic disparities in mortality rates due to CAD in hypertensive patients aged 25 and older from 1999 to 2020. Methods: The CDC WONDER database's mortality data from 1999 to 2020 was used for a retrospective analysis. Average Annual Percentage Change (AAPC) and Annual Percent Change (APC) were used to evaluate trends and calculate age-adjusted mortality rates (AAMRs) per 100,000 people. The year, sex, race/ethnicity, and geographic regions were used to stratify the data. Results: Between 1999 and 2020, CAD in hypertension caused 1,512,89 medical facilities, accounting for 37.9% of all deaths. With an AAPC of 1.88 (95% CI: -0.81 to 4.36, p = 0.118), the overall AAMR grew from 7.7 in 1999 to 36.0 in 2020. There was a notable increase between 1999 and 2001 (APC: 30.07, p = 0.040) and a minor growth between 2001 and 2020 (APC: 0.85, p = 0.030). Adult men had higher AAMRs than women (men: 40.2; women: 25.2), with increases for both sexes [Men: AAPC: 4.75, p = 0.002; Women: AAPC: 2.70, p = 0.058]. AAMRs varied significantly by race, highest among Black individuals (39.9), followed by Whites (31.4), American Indians (30.4), Hispanics (27.7), and Asians (21.3). The AAMR increased for all races from 1999 to 2020, most notably in American Indians (AAPC: 4.91, p = 0.004). AAMRs varied by state, from 16.4 in Utah to 51.4 in West Virginia. The Midwest had the greatest regional death rate (33.6), followed by the West (31.1), Northeast (31.0), and South (30.9). Nonmetropolitan areas had higher AAMRs than metropolitan areas (34.7 vs. 31.0), with a greater increase in nonmetropolitan areas (AAPC: 6.22, p &lt; 0.000001). Conclusion: This analysis reveals significant demographic and geographic disparities in mortality rates due to CAD in hypertensive adults in the U.S. The AAMR has increased fivefold over the past two decades, particularly among certain racial groups and geographical regions. These findings underscore the urgent need for targeted interventions and equitable healthcare access to mitigate these disparities and improve outcomes.
