Researchers from academic institutions across the U.S. and Pakistan used CDC data between 1999 and 2023 to analyze age-adjusted cardiac arrest mortality rates in heart failure patients 25 and older.
Here are five things to know from the study:
- During the study period, there were 1,139,693 deaths in the U.S. from cardiac arrest among adults 25 and older.
- After adjusting for age, the overall mortality rate per 100,000 people fell from 25.3 in 1999 to 20.6 in 2023.
Among men, the rate fell from 29.5 in 1999 to 26.2 in 2023. Among women, the rate fell from 22.6 to 16.2.
- The overall decline in age-adjusted cardiac arrest mortality rate did not occur at a steady rate.
Between 1999 and 2011, there was a 2.95 decrease, followed by a 1.13 increase between 2011 and 2018.
A significant 5.10 increase occurred between 2018 and 2021, followed by a 4.05 decrease between 2021 and 2023.
- Researchers found racial and ethnic disparities in the data.
The overall age-adjusted cardiac arrest mortality rate for the non-Hispanic Black population in the U.S. was 28.8, compared to 22.8 for the Hispanic or Latino population, 19.5 for the non-Hispanic white population and 18.1 for non-Hispanic individuals from other racial or ethnic populations.
- Mortality from cardiac arrest varied significantly among geographic regions.
The Western U.S. experienced the highest mortality rate at 28.9, followed by 25.6 in the Northeast, 17.9 in the South and 12.5 in the Midwest.
The state with the highest cardiac arrest mortality rate was Mississippi at 52.8. Maryland had the lowest cardiac arrest mortality rate at 4.3.
