Covid-19 and stroke

According to Associate Professor Nguyen Huy Thang – Head of Cerebrovascular Disease Department – 115 People’s Hospital in Ho Chi Minh City, based on recent evidence, people see an association between Covid-19 and stroke.

Through many publications, the rate of stroke patients during Covid-19 infection ranged from 0.9 to 2.7% (average 1.2%). Compared with other viral infections like Influenza, the chance of having a stroke related to a Covid-19 infection is seven times higher.

Research published at the American Stroke Conference 2022 shows that the risk of having a stroke is highest in the first 3 days after being diagnosed with Covid-19 (increased 10 times). The risk of stroke decreased gradually over periods of 4 – 7 days, 8 – 14 days, and 15 – 28 days. After 1 year, although the risk of stroke in patients with a history of Covid-19 infection was significantly lower, but higher than that of the general population.

Associate Professor Thang said that after recovering from Covid-19, patients can have an ischemic stroke by 3 main mechanisms:

firstdue to the mechanism of increased inflammatory response, leading to inflammation of the blood vessels.

Second, causes hypercoagulability, leading to thrombus formation in the arterial, venous and organ systems.

Prevention of stroke

For patients suffering from acute Covid-19 infection, Associate Professor Thang said that the stroke-causing mechanism of Covid-19 is very much related to the formation of blood clots, causing blood vessel embolism.

However, recently published clinical trials have not demonstrated the benefit of routine use of anticoagulants or antiplatelet agents in patients with Covid-19 for stroke prevention.

For the post-Covid-19 situation, Associate Professor Thang said that people in the high-risk group may have a stroke after being infected with Covid-19 because there are many other risk factors such as high blood pressure, diabetes, and metabolic disorders. lipids, smoking, obesity…

Stroke prevention in post-Covid-19 patients includes only tight control of risk factors.

The patient still has to adhere to taking all kinds of medication, enough time. Currently, all diseases that cause stroke require lifelong medication maintenance. For example, high blood pressure cannot be completely cured, but only medications can be used to control blood pressure levels. Similarly, blood sugar too, to be effective, patients need to adhere to treatment and use long-term drugs, if only treatment for a few months and then stop, it will return to the same level, increasing the risk of stroke. .

In addition to managing the underlying disease, patients need to change their lifestyle, quit smoking, limit alcohol, and exercise to reduce diseases such as hypertension, diabetes, thereby reducing the risk of stroke. stroke in the future.

For healthy people without the above factors, there is no need for post-Covid-19 screening for stroke and no need to screen with expensive modern imaging equipment unless the person himself disease with symptoms of stroke, transient stroke.
