New research has found that patients hospitalized for COVID-19 had a higher risk of stroke, compared to patients who had similar infectious conditions such as flu and sepsis in previous studies.
Those who had an ischemic stroke were more likely to be older, male, black or high blood pressure, type 2 diabetes, or irregular heartbeat (atrial fibrillation) compared to those who had had an ischemic stroke. other COVID-19 patients, according to late-breaking science presented. today at the American Stroke Association’s 2021 International Stroke Conference.
The meeting was held virtually from March 17-19, 2021 and is the first global meeting for researchers and clinicians dedicated to stroke science and brain health.
For this analysis, researchers accessed the American Heart Association’s COVID-19 Cardiovascular Disease Registry to study stroke risk in patients hospitalized with COVID-19, their demographics, medical history, and survival. to the hospital. COVID-19 registry data extracted for this study included more than 20,000 patients hospitalized for COVID-19 across the United States between January and November 2020.
“These results suggest that COVID-19 may increase the risk of stroke, although the exact mechanism is still unknown,” said lead study author Saate S. Shakil, MD, cardiology researcher at the University of Washington in Seattle. “As the pandemic continues, we are discovering that the coronavirus is not just a respiratory disease, but a vascular disease that can affect many organ systems.”
Two hundred and eighty-one people (1.4%) in the COVID-19 cardiovascular disease registry have had a stroke confirmed by diagnostic imaging while in hospital. Of these, 148 patients (52.7 percent) suffered an ischemic stroke; 7 patients (2.5 percent) had a transient ischemic attack (TIA); and 127 patients (45.2 percent) had a hemorrhagic stroke or an unspecified type of stroke.
Analysis of patients with COVID-19 also revealed: – Patients with stroke of any type were more likely to be male (64%) and older (65 years on average) than patients without stroke (61 years on average).
Forty-four percent of patients with ischemic stroke also had type 2 diabetes compared to about one-third of patients without stroke, and most patients with ischemic stroke had high blood pressure (80%) compared to those without stroke. patients without stroke (58 percent);
Eighteen percent of patients with ischemic stroke had atrial fibrillation, while 9 percent of those without stroke also had atrial fibrillation;
Patients with stroke spent an average of 22 days in hospital, compared to 10 days in hospital for patients without stroke; and
Hospital deaths were more than twice as high in stroke patients (37 percent) than in patients without stroke (16 percent).
In addition, the risk of stroke varied by race. Black patients represented 27 percent of patients in the COVID-19 cardiovascular disease registry pool for this analysis; however, 31 percent of ischemic stroke cases were in black patients.
“We know the COVID-19 pandemic has disproportionately affected communities of color, but our research suggests black Americans may also have a higher risk of ischemic stroke after contracting the virus,” said Shakil. “Stroke itself can have devastating consequences and recovering from COVID-19 is often a difficult road for those who survive. Together they can wreak significant havoc on patients who have had both conditions.”
Shakil added, “It is more important than ever to curb the spread of COVID-19 through public health interventions and widespread vaccine distribution.
