Higher than expected risk of stroke among COVID-19 patients

DALLAS, March 19, 2021 – A new study found that patients hospitalized with COVID-19 had a higher risk, compared to patients with infectious diseases such as influenza and sepsis in preclinical studies hand. Those who had an ischemic stroke were more likely to be older, male, black race, or with high blood pressure, Type 2 diabetes or irregular heartbeat (atrial fibrillation) compared with COVID-19 patients. another, according to the late breakout science presented today at the International Stroke Conference of the American Stroke Association 2021. The meeting is being held almost, March 17-19, 2021 and is a major global meeting for researchers and clinicians dedicated to the science of stroke and brain health.

For this analysis, researchers accessed the American Heart Association’s COVID-19 Cardiovascular Disease Index to study stroke risk among patients hospitalized for COVID-19, their demographic characteristics, medical history, and side survival. hospital interior. COVID-19 Table data extracted for this study included more than 20,000 hospitalized patients with COVID-19 across the U.S. between January and November 2020.

“These findings suggest that COVID-19 may increase the risk for stroke, although the exact mechanism for this is not known for sure,” said study lead author Saate S. Shakil, MD , a cartographer at the University of Washington in Seattle. “As the pandemic continues, we discover that coronavirus is not just a respiratory illness, but a viral infection that can affect many organ systems.”

Two hundred and eighty-one individuals (1.4%) in the COVID-19 CVD Table on stroke were confirmed by study imaging during hospitalization. Of these, 148 patients (52.7%) had an ischemic stroke; 7 patients (2.5%) had a transient ischemic attack (TIA); and 127 patients (45.2%) experienced a bloating stroke or an undiagnosed type of stroke.

The COVID-19 patient study also found:

  • Those with stroke of any type were more likely to be male (64%) and older (average age 65) than non-stroke patients (average age 61);
  • About one-third of non-stroke patients had Type 2 diabetes against about one-third of non-stroke patients, and most had high blood pressure (80%). ‘ischemic stroke patients compared with non-stroke patients (58%);
  • 18% of ischemic stroke patients had atrial fibrillation, and 9% of non-stroke patients had atrial fibrillation;
  • Patients who had a stroke spent an average of 22 days in hospital, compared with 10 days in hospital for non-stroke patients; and
  • In-hospital deaths were more than twice as high among stroke patients (37%) compared with non-stroke patients (16%).

In addition, the risk of stroke varied by race. Black patients made up 27% of the patients in the COVID-19 CVD Registry bath for this analysis; however, 31% of cases of ischemic stroke were among black patients.

“We know that COVID-19 pandemic disease has had a disproportionate impact on color communities, but our research shows that Black Americans may have a higher risk of ischemic stroke after get a virus, too, “Shakil said. “Stroke alone can have a devastating effect and overcoming COVID-19 is often a difficult path for those who survive. Together, they can impose a huge tax on patients who have acquired both conditions.”

Shakil said, “It is more important than ever that we prevent the spread of COVID-19 through public health interventions and widespread vaccination.”


In April 2020, the American Heart Association created the CVID-19 CVD Tablet within weeks of the rapid spread of the global pandemic and to provide sightings to hospitalized patients with the novel coronavirus. The Society’s Get With The Guide’s robust registration infrastructure has enabled rapid data collection, including over 37,000 patient records and over 135,000 laboratory reports, with more than 160 registered registration sites (data such as 2/23/21).
