Study shows socioeconomic status linked to heart failure mortality in US

Heart failure is a medical condition that results when the heart muscle is not strong enough to effectively circulate blood. A variety of treatments exist to address this disease, yet it continues to carry a poor prognosis. A new study from University Hospitals showed that a person's address can help predict their chance of mortality from heart disease.

The study found that the variability in heart failure mortality in the United States is at least partially explained by measures of wealth and socioeconomic status. In the United States, counties that have high rates of poverty and other measures of social deprivation also have higher rates of death from heart failure. Socioeconomic status may play an important role in heart failure because access to expensive medications and other therapies can be more available in affluent communities. Furthermore, areas with higher poverty levels may have reduced access to quality healthcare in general.

The study analyzed 1,254,991 heart failure deaths across 3,048 counties between 1999 and 2018. The investigators used multiple indicators of employment, poverty, income, housing and education to determine a person's level of socioeconomic deprivation.

This study highlights the importance of addressing socioeconomic factors to improve heart failure outcomes nationally.

"Analysis of trends in heart failure mortality shows that these disparities have persisted throughout the last two decades" said Graham Bevan, MD, a resident physician at University Hospitals and the first author of the study.

"Living in a particular county should not mean you're more likely to die from heart failure," said Sadeer G. Al-Kindi, MD, cardiologist with UH Harrington Heart & Vascular Institute. "University Hospitals has a history of addressing health care disparities in underserved communities and armed with the information from this study, we can thoughtfully create solutions to better serve these populations."
