Eighty percent of heart disease deaths can be prevented. So, why aren’t we doing more? Getty Images
Much research has been conducted showing the particularly high rates of heart-related health risks faced by black adults.
Now, new research from the American Heart Association (AHA) offers some explanation why blacks — especially women — seem to experience higher rates of sudden cardiac death than their white counterparts do.
The new research suggests cultural and socioeconomic disparities, such as income level and education, as well as risk factors such as hypertension and diabetes, account for these higher rates.
This was published earlier this month in the journal Circulation.
“The shocking thing about this is that this is the current situation in the United States, where given all the resources, all the technology, and all information we have, we shouldn’t be seeing this kind of health disparity,” Dr. Icilma Fergus, associate professor of medicine at Mount Sinai Medical Center in New York City, told Healthline.
Fergus, who is also a spokesperson for the AHA, said that this gap that opens up between racial lines in our current health system has to do with a lack of resources.
She said that more affluent, educated white communities have better access to information about heart health — education on everything from eating the right foods to recognizing the signs of a stroke to administering CPR — is prevalent and clear.
Fergus stressed this isn’t the case in poorer black communities.
“I think it’s something that can be remedied,” she added, pointing out that 80 percent of the heart disease issues in the groups they studied could have been prevented if they “had more access to the resources, education, and preventative measures.”
The data for the study came from the Atherosclerosis Risk in Communities (ARIC) study, which is a large-scale heart disease study that focused on four American communities — the Minneapolis suburbs; Jackson, Mississippi; Forsyth County in North Carolina; and Washington County in Maryland. It followed 11,237 white participants and 3,832 black participants for nearly three full decades.
In the new report, the ARIC study found that by age 85, 9.6 percent of people who suffered sudden cardiac death were black men and 6.6 percent were black women. These numbers were strikingly higher compared to their white male and female counterparts, whose numbers stood at 6.5 percent and 2.3 percent, respectively.
Sudden cardiac death is what it sounds like — an unexpected death that results from loss of heart function or cardiac arrest, according to Cleveland Clinic.
It causes about 325,000 adult deaths in the United States each year.
Most of these deaths occur in adults in their mid 30s to mid 40s. Sudden cardiac death affects men twice as often as it affects women, which mirrors the findings of this new study.
Sudden cardiac death is rare in children, affecting about one or two per 100,000 kids each year, the Cleveland Clinic reports.

irregular heartbeats, that resulted in these sudden cardiac deaths. More

“Low income and lack of education are associated with unhealthy behaviors, low disease awareness, and limited access to care, which could all contribute to poor outcomes,” said lead author of the study Eliseo Guallar, PhD, in a press release. “However, our understanding of the mechanisms for racial differences in sudden cardiac death is still incomplete and additional research is needed.”
