AmericaElderly people can develop ischemic stroke in the first three days of contracting Covid-19, according to new research from the Centers for Disease Control and Prevention.
The study is scheduled to be published during the American Stroke Association’s International Stroke Conference, which will take place online from February 8 to February 11.
“Stroke is a complication that can occur soon after contracting Covid-19. Vaccinating and taking preventive measures against Covid-19 is very important, helping to reduce the risk of infection and complications such as stroke.” , said Dr. Quanhe Yang, lead author of the study at the CDC’s Heart and Stroke Institute.
The CDC study focused on ischemic stroke, a blood vessel blockage. Experts examined the health records of more than 37,000 people from April 1, 2020 to February 28, 2021. Strokes in the 7 days before and 28 days after the positive diagnosis are called the control period. Volunteers with an average age of 80.57% were women.
The analysis showed that the highest risk of stroke occurred in the first three days after nCoV infection, 10 times higher than in the control period. After day three, the risk of stroke rapidly decreased, but was still higher than in the control period. Specifically, from day 4 to day 7, the risk of stroke was 60% higher. From day 8 to day 14, the risk was 44% higher than in the control period.
“The new finding could be of interest in stroke diagnosis, treatment and care in people with Covid-19. However, further research is needed to clarify stroke-related factors such as age.” , Dr. Yang said.
The American Heart Association and the CDC support two shots of the vaccine and a booster dose. Experts say this is the best way to reduce the risk of nCoV infection, prevent severe disease or death, especially in people with underlying medical conditions.
Previous studies have assessed the risk of stroke in adults with nCoV. But their results were inconsistent, with little focus on older adults, a group at high risk of stroke.
