A recent decline in heart failure-related deaths in the United States has reversed, and those types of deaths are now climbing nationwide, especially among adults ages 35 to 64.
The trend, which also revealed some racial disparities, was found in a research paper published in the Journal of the American College of Cardiology on Monday.
The paper points to an increase in the prevalence of obesity and diabetes as possibly driving a parallel rise in heart failure deaths.
The research demonstrates “that greater loss of life from heart failure is occurring, especially premature death in those under the age of 65,” said Dr. Sadiya Khan, an assistant professor of cardiology at Northwestern University’s Feinberg School of Medicine in Chicago, who was first author of the paper.
The paper doesn’t distinguish why this rise in heart failure deaths occurred – for instance, are more younger adults developing heart failure, or is heart failure more deadly now? “Our suspicion is that it is likely the former, because of the obesity, hypertension and diabetes epidemics,” Khan said.
About 5.7 million adults in the United States have heart failure, according to the US Centers for Disease Control and Prevention. Heart failure is more common in people who are obese or overweight, as excess weight can put strain on the heart, and those who have a history of heart attack, among other risk factors.
The reversal of a trend
The new paper involved analyzing heart failure-related mortality data in the CDC’s Wide-Ranging Online Data for Epidemiologic Research database. The researchers took a close look at deaths between 1999 and 2017 among adults aged 35 to 84.
Overall, the researchers found that rates for heart failure death dropped significantly from 1999 through 2012 but then increased through 2017.
The researchers also found disparities by age and race. Black men had a 1.16-fold higher heart failure death rate than white men in 1999, compared with a 1.43-fold higher heart failure death rate in 2017. Meanwhile, black women had a 1.35-fold higher heart failure death rate than white women in 1999, compared with a 1.54-fold higher heart failure death rate in 2017, the data showed.
Those disparities were more pronounced among adults 35 to 64 than those 65 to 84, according to the data.
All in all, “we are demonstrating for the first time that heart disease deaths from heart failure are increasing and that increase is disproportionately higher in young black men and women,” Khan said.
