Key result
Black race is linked to ~24% lower EVT rates for acute ischemic stroke versus White race.
Why the study?
Access to and utilization of endovascular therapy for acute ischemic stroke may not have extended uniformly across racial and ethnic groups, requiring assessment of potential disparities.
Does race/ethnicity affect the utilization of endovascular therapy in patients with acute ischemic stroke?
Cohort (n=40,814)
Yes
Does race/ethnicity affect the utilization of endovascular therapy in patients with acute ischemic stroke?
Relative Risk: 0.76 (95% CI 0.66–0.88)
Absolute Event Rate: 4.1% vs 5.3%
p-value: p=<0.001
Black patients with acute ischemic stroke are significantly less likely to receive endovascular therapy compared to White patients, despite having similar or greater access to capable hospitals.

Observed racial disparity in EVT use warrants equity-focused investigation; leaves open mechanisms and solutions pending prospective data.
A 2022 study conducted a cohort in Acute ischemic stroke (n=40,814). Black race vs. White race was evaluated on Endovascular therapy (EVT) utilization (RR 0.76, 95% CI 0.66-0.88, p=<0.001). Black race was associated with lower rates of endovascular therapy for acute ischemic stroke compared with White race (4.1% vs 5.3%; adjusted RR 0.76; 95% CI 0.66-0.88; P<0.001).
