Black patients with acute ischemic stroke are 25% less likely to receive endovascular therapy compared to white or Hispanic stroke patients, according to research from The University of Texas Health Science Center at Houston (UTHealth Houston).

The study – led by Youngran Kim, PhD, postdoctoral research fellow in the Department of Neurology with McGovern Medical School at UTHealth Houston, andSunil A. Sheth, MD,associate professor of neurology with the medical school – also found that this difference occurred despite the fact that Black patients present at facilities where endovascular therapy is available just as often as white patients.

The authors’ findings were published last month inStroke,a peer-reviewed medical journal distributed on behalf of the American Heart Association.

“What this shows is that, even with advancements in technology and treatments, Black patients still have less of a chance of getting the most effective treatment,” Kim said. “Perhaps there is some institutionalized racism, but this persistent trend is something we need to address in the community and on the health care provider side.”

A data analysis of 40,814 acute ischemic stroke patients who were treated in Texas in 2019 revealed that, overall, rates of endovascular therapy were 4.1% among Black patients, 5.3% among white patients, and 4.8% among Hispanic patients, despite the fact that Black patients had similar admissions to endovascular therapy-performing hospitals and greater admissions to comprehensive stroke centers. The analysis of nationwide sample data also confirmed this finding of lower utilization of endovascular therapy for Black patients.

“The key follow-up question to our study is why this is happening,” Sheth said. “These treatments are incredibly effective at reducing disability after stroke and saving lives, so it is important that we make sure that everyone suffering from stroke has access to these treatments.”

Endovascular therapy is known to be an effective treatment for this type of stroke, but it relies on specialized capabilities that are not available in every hospital where acute ischemic stroke is treated.

Sheth hopes these findings will give medical professionals a target goal to address the 25% disparity he and Kim found between Black and white patients in terms of who received the treatment.
