Dallas, TX – People living in counties with high rates of poverty are more likely to die from heart failure compared to people living in more affluent areas, according to new research published in Journal of the American Heart Association, the Open Access Journal of the American Heart Association.
“When you look at a map of the United States, you will see that the poorer counties have the highest death rates from heart failure,” said Khansa Ahmad, M.D., the study’s lead author and a preventive cardiology fellow at the Alpert Medical School of Brown University in Providence, Rhode Island.
Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood to meet the body’s needs for blood and oxygen.
To explore geographical differences, the researchers reviewed data from 3,000 United States counties looking for potential links between heart failure deaths and county-level poverty, education, unemployment and health insurance status. Data was pulled from the Centers of Disease Control and Census Bureau databases.
- County-level poverty had the strongest correlation with heart failure deaths.
- Heart failure deaths increased by about five deaths per 100,000 for each 1% increase in county poverty status.
- A difference of approximately 250 deaths per 100,000 between the poorest and the most affluent counties was observed.
- About two thirds of the relationship between country poverty and heart failure deaths was explained by the prevalence of diabetes and obesity across the counties.
- The link between poverty and heart failure deaths was the strongest in counties in the southern census region.
“Interventions to help people in poor areas, where obesity is more common, to attain and maintain a healthy body weight should be investigated in developing policies to improve heart failure outcomes across the US counties,” said Wen-Chih Wu, M.D., study co-author and chief of cardiology and research health science at the Providence VA Medical Center and associate professor of medicine at Brown University.
The American Heart Association is working to break these links through community action plans that address specific issues, like obesity, food deserts and access to care in poor communities across the U.S.
