Coronavirus infection doubles the risk of certain strokes

While initially the focus was on the respiratory complaints in infections with the new SARS-CoV-2 coronavirus, it is now clear that COVID-19 can have numerous other consequences. According to a recent study, these apparently also include strokes with a occlusion of the large blood vessels (LVO stroke; LVO = large vessel occlusion)

Other studies have already shown evidence of a connection between COVID-19 and the risk of stroke. For example, an increase in the frequency of acute ischemic strokes was observed in COVID-19 sufferers with acute neurological symptoms. In the current study, researchers at the Icahn School of Medicine at Mount Sinai have now identified possible connections between coronavirus infection and the occurrence of an LVO stroke. The study was published in the specialist journal “American Journal of Roentgenology”

329 people with stroke were examined

The retrospective case-control study included a total of 329 people (175 men, 154 women; average age 66.9 years), all of whom were hospitalized in a clinic in New York from March 16 to April 30, 2020 for a stroke were. Of the participants, 35.3 percent (116 people) had an acute ischemic stroke, 21.6 percent (71 people) had an LVO stroke, and 14.6 percent (48 people) had a small vascular occlusion (SVO stroke) ; SVO = small vessel occlusion) found.

Significantly more LVO strokes

Of the study participants, 38.3 percent (126 people) had COVID-19 and 61.7 percent (203 people) tested negative for the virus. The latter served as a control group for stroke risk. An LVO stroke was present in 31.7 percent of those infected, but only in 15.3 percent of the people in the control group, the researchers report. SVO strokes occurred in 15.9 percent of those infected and in 13.8 percent of the control group.

Risk more than doubled

Even after adjusting the results for possible distorting factors, it was clear that the risk of an LVO stroke in people with COVID-19 was more than twice as high as in the control group, the researchers report. COVID-19 was clearly associated with the risk of an LVO stroke, but not with the risk of an SVO stroke. Dabi formed this “the first study that describes a connection between COVID-19 and strokes of the large blood vessels,” emphasizes Shingo Kihira from the Icahn School of Medicine at Mount Sinai.
