More patients with a stroke get rid of a mechanical clot, but racial differences remain

DALLAS, March 19, 2021 – Mechanical removal of blood clots causes a growing stroke, but racial differences in treatment persist, according to late science presented today at Co American Stroke Association International Stroke Conference 2021. The inaugural meeting is March 17, 1919, and is a major global meeting for researchers and clinicians dedicated to the science of stroke and brain health.

Mechanical clot removal is a non-surgical treatment or endovascular treatment that uses tiny tubes, or catheters, to remove a blood clot. In 2015, several major clinical trials confirmed that endovascular therapy effectively treated stroke caused by obstruction in a large blood vessel (ischemic stroke). In 2018, the American Heart Association’s stroke treatment guidelines were updated to recommend endovascular therapy to improve the perceptions some stroke patients may have of recovering from an operation. However, previous research has shown that members of some underrepresented ethnic / ethnic groups are less likely to receive recommended treatments such as endovascular therapy.

This study compared endovascular therapy use and stroke recovery among patients of different races / ethnicities before and after 2015. Between April 2012 and June 2019, researchers reviewed data in the Get With The program American Heart Association Guidelines®-Stroke, which includes a large database of information on stroke treatment at hospitals across the U.S. Since 2003, more than 2,000 hospitals have submitted more than 5 million patient records into the program database.

Searched by researchers:

  • Overall, 14% of 302,965 patients received potential endovascular treatment and, in all groups, endovascular treatment increased beyond the study.
  • However, black patients were 32% less likely to receive endovascular treatment by 2015 and still 17% less likely to receive it after 2015 compared to non-Hispanic white patients.
  • Differences also appeared in relation to stroke survival. In terms of short-term outcomes, patients from ethnic and ethnic groups were better represented than non-Hispanic white patients. In addition, Black, Hispanic, and Asian patients were more likely to return home and less likely to die while in hospital or being discharged to hospital care.
  • Three months later, however, black patients were 16% less likely and Asian patients 30% less likely to be able to function independently, compared to non-Hispanic white patients.

“We are encouraged that the treatment gap for Black patients has narrowed since 2015, but it remains important and worrying. The most striking finding was the difference between short-term and long-term outcomes in non-Hispanic white patients versus patients elsewhere. ethnic groups and ethnicity, “said lead study author Faheem G. Sheriff, MD, assistant professor of neurology at Texas Tech University Health Science Center in El Paso, Texas.” There is still a lot of work to be done in determining the key reasons for these differences and how best to improve access and equitable care for all patients. “

The Sheriff continued, “Once these key causes are identified, we can focus on an action plan to reduce these differences, both for accessing and overcoming endovascular treatment. after that, especially post – release care. “


According to the American Heart Association Heart and Stroke Statistics – Update 2021, when assessed separately from other cardiovascular disease, stroke ranks No. 5 among all causes of death in the U.S., causing 147,810 deaths in 2018. A stroke occurs when a blood vessel closes. to or in the brain either blocked or exploding, preventing blood and oxygen from reaching the entire brain. Treatment to restore blood flow to the brain is essential to improve results and survival.

To identify stroke symptoms that need immediate treatment, the American Stroke Association recommends that everyone remember the acronym FAST for facial drooping, arm weakness, speech difficulty, call time 9-1-1 . Fortunately, it is possible to prevent most strokes through healthy lifestyle choices: no smoking; eating healthy food; be physically active; maintaining a healthy body weight; and control high blood sugar, cholesterol and blood pressure.

Results in size and duration when a mechanical clot is removed for major heart strokes

Mechanical clot removal without clot busters can be enough of a stroke treatment

Removing clot longer than normal treatment time, still improves quality of life after stroke
