Despite sustained progress in cardiovascular disease survival across the United States, a new analysis highlights striking geographic disparities. Researchers examining national data found that county-by-county variation in heart disease outcomes is substantial—and in some cases larger than the gaps seen between states.
The findings, reported in the Journal of the American College of Cardiology, suggest that local factors such as healthcare access, socioeconomic conditions, and prevention efforts may play a powerful role in shaping survival. The study adds to a growing picture of U.S. cardiovascular health as unevenly distributed, even within the same state.
For clinicians and policymakers, the results underscore the need to look beyond state-level averages when targeting resources and interventions. Addressing local hotspots of poor outcomes could be key to narrowing the remaining gaps in heart disease survival.
