Research: When is the risk of stroke higher for seniors with covid?
The risk of developing an ischemic stroke in the elderly diagnosed with Covid-19 is higher within the first three days of diagnosis of infection
The risk of developing an ischemic stroke in the elderly diagnosed with Covid-19 is higher within the first three days of being diagnosed with the infection, according to a new US scientific study.
Researchers at the Centers for Disease Control and Prevention (CDC) in the United States, who made the announcement at an international conference on the American Stroke Association in New Orleans, analyzed data from nearly 37.400 people over the age of 65 (mean age 80). , who were diagnosed with coronavirus in 2020 and 2021 and were hospitalized.
It was found that the highest risk of stroke exists within the first three days of diagnosis, being ten times higher than either in the period before diagnosis Covid-19 or one month after diagnosis. After the first three days after diagnosis, the risk of stroke decreases rapidly, but remains relatively higher than in the period before diagnosis. Covid-19 or one month after diagnosis.
Analytically, the 4 to 7 days after the diagnosis the risk is 60% higher, the 8 to 14 days is 44% higher, while 15 to 28 days only 9% higher. People aged 65 to 74 have a higher risk of having a stroke after diagnosis Covid-19 compared to those over 85, as well as those who do not have a history of stroke.
