Stroke with COVID-19 developing less frequently than previously thought - study
A major new study shows stroke is a relatively rare complication of coronavirus infection. But against the background of infection, it is extremely difficult.

The work, published in Stroke magazine, suggests that strokes associated with COVID-19 do not develop as often as stated in previous reports.
Fewer than 1% of hospitalized patients with confirmed COVID-19 develop stroke, according to new data. This is significantly lower than the figures demonstrated by small studies conducted in China and Italy (2-5%).
A new study has confirmed that, against the background of coronavirus infection, stroke progresses in younger patients, its course is worse, and the risk of death is seven times higher than in uninfected patients.
In the work, scientists analyzed data from 3,556 patients with COVID-19 from the Langon hospital network in the United States, who were treated between March 15 and April 19, 2020. During this period, stroke developed in 32 patients. They compared the characteristics of the disease with data on the course of strokes in people who are not infected with the coronavirus.
During the study, 63% of patients with stroke and COVID-19 died. The average death rate for ischemic stroke in the United States is 9%. The study also showed that at least 56% of strokes in COVID-19 develop due to increased blood clotting under the influence of infection.
“Our research shows that stroke is a rare but very important complication of coronavirus, given that these strokes are more severe than strokes in people who test negative for the virus,” said Shadi Yaghi, assistant professor at New York University., co-author of the study.
