The purpose of this study was to review the link between COVID-19 and acute ischemic stroke.

41 cases and 82 control subjects, from 6 hospitals in Manhattan, Queens, and Brooklyn, were matched by age, sex, and risk factors.

Case subjects had confirmed ischemic stroke while control subjects did not have any evidence of ischemic stroke.

Of patients that had acute ischemic stroke, 46.3% had COVID-19 infection while in the control group, 18.3% had COVID-19.

It was found that COVID-19 had a significant, independent association with acute ischemic stroke after adjusting for age, sex, and risk factors.
