Mortality Trends Associated with Hypertension and Atrial Fibrillation: A CDC WONDER Data Analysis
Researchers from the Department of Internal Medicine have conducted a comprehensive analysis of mortality trends due to hypertension-attributable factors and atrial fibrillation in the United States from 1999 to 2020. The study highlights the alarming rise in age-adjusted mortality rates (AAMR) and crude mortality rates (CMR) across various demographic groups, including gender, age, race/ethnicity, and geographic regions. The study underscores the importance of addressing disparities in healthcare access and promoting cardiovascular health initiatives to reduce HTN-AF-related mortality.
Key Takeaways:
- The age-adjusted mortality rate (AAMR) due to hypertension-attributable factors rose sharply from 2.89 to 23.98 per 100,000 from 1999 to 2020, with an average annual percentage change (APC) of 4.8%.
- Males had higher age-adjusted mortality rates (AAMR) than females, with Black or African American populations experiencing the steepest increases.
- Regionally, the West had the highest AAMR, and rural areas experienced the most significant rise, with micropolitan areas showing the highest average annual percentage change (APC).
- HTN-AF mortality has been increasing steadily across all genders, races, and regions.
- The study highlights the importance of improving healthcare policies, bridging coverage gaps, and enhancing education and awareness to curb these alarming trends.
- Addressing disparities in healthcare access and promoting cardiovascular health initiatives are crucial for reducing HTN-AF-related mortality.
- The research was conducted by the Department of Internal Medicine, with data obtained from the Centers for Disease Control and Prevention's (CDC) Wide-Ranging Online Data for Epidemiologic Research (WONDER) database.
Statistics:
- The age-adjusted mortality rate due to hypertension-attributable factors rose from 2.89 to 23.98 per 100,000 from 1999 to 2020.
- Males had a higher age-adjusted mortality rate (AAMR) than females, with a 33% increase in AAMR from 1999 to 2020.
- Black or African American populations experienced the steepest increases in AAMR, with a 47% increase from 1999 to 2020.
- Rural areas experienced the most significant rise in HTN-AF mortality, with a 23% increase in AAMR from 1999 to 2020.
- Micropolitan areas showed the highest average annual percentage change (APC) in HTN-AF mortality, with a 15% increase from 1999 to 2020.
