After more than a decade of declines in heart failure-related deaths in the United States, more Americans are now dying from the condition as the obesity and diabetes epidemics rage on, according to a new study by Northwestern Medicine.
The increase in heart failure deaths was especially high in adults between the ages of 35 to 64, particularly in young black men.
"We've seen a lot of progress in the last two decades with certain medical advancements," said Dr. Sadiya Khan, who authored the study, but "these data are suggesting that we need to do more in the realm of prevention."
Khan said this trend is expected to get worse because of the number of Americans that suffer from obesity and diabetes, which negatively impact heart health. More than 93 million American adults are obese, while 30 million live with diabetes.
Heart failure is when the heart muscle doesn't pump blood as efficiently as it should. It can cause shortness of breath, swelling in the legs and feet, weakness, persistent coughing and death. About 5.7 million U.S. adults live with the condition.
The study, which examined more than 47 million death certificates from 1999 to 2017 using a Centers for Disease Control database, found the number of people dying from heart failure is slowly creeping up after years of reductions in death rates.
The number of Americans aged 35 to 84 that died from heart failure decreased from 79 deaths per 100,000 people in 1999 to 54 deaths per 100,000 people in 2012. But in 2017, there were 59 deaths per 100,000.
The increase in heart failure deaths was even more notable for young adults, but the study found black men and women were impacted much more than white men and women.
For black men, there were nearly 38 heart failure deaths per 100,000 in 2017, compared to 14 deaths per 100,000 for white men. Black women saw about 20 deaths per 100,000 that year, compared to 7 per 100,000 for white women.
Khan said young black adults were so much more likely to die from heart failure because they are more susceptible to adverse health conditions that can impact heart health, including high blood pressure. However, Khan also noted that "social determinants" may also contribute to black people's increased likelihood of dying from heart failure.
Khan said black people more often live in poverty and have less access to health care, meaning certain conditions can go "unrecognized and undertreated."
Though black people are more likely to die from heart failure, all young adults saw a rise in deaths related to the condition. For black men in 2012, there were about 29 deaths per 100,000, while there were 11 deaths per 100,000 for white men. For black women there were 17 deaths per 100,000, while there were 7 per 100,000 for white women.
To combat the rising rate of heart failure deaths, Khan said people need to focus more on maintaining a healthy weight and managing health blood pressure and glucose levels. She also noted that there needs to be increased health care for young adults because they "are kind of getting lost until they hit that Medicare age" at 65.
"There needs to be a safety net for these people," Khan said.
