According to new research results, patients with Covid-19 may suffer heart and brain damage.

SARS-CoV-2 is a corona virus, known for its attack on the respiratory system, causing common flu-like symptoms such as a dry cough and fever. Previous studies have shown that patients with Covid-19 will suffer long-term lung damage. However, the consequences of the disease did not stop there.

According to Gizmodo, many doctors and scientists report a series of cases of heart damage during SARS-CoV-2 infection, which can lead to cardiac arrest and death.

In an article published in the Journal of the American Medical Association, Matt Arentz, a graduate student at the University of Washington (USA) and colleagues reported that up to 1/3 of Covid-19 patients in intensive care (ICU) ) had a heart problem.

In addition, a few cases have symptoms of a nervous system attack, such as swelling of the brain, convulsions, stroke, loss of taste and smell. Even, a large proportion of Covid-19 patients with digestive disorders, evidence that the virus affects this organ system.

Gizmodo commented that the appearance of a series of injuries in various organs shows that the immune system’s response to the virus sometimes has a negative effect.

Covid-19 patients may experience Cytokine Release Syndrome, a phenomenon where the immune system produces too many immune cells throughout most of the body, attacks both healthy cells and worsens existing conditions. have.

However, the scientists did not rule out the possibility that SARS-CoV-2 virus could directly attack the patient’s heart and brain.

Facing the outbreak of Covid-19 globally, scientists are racing to find specific drugs and vaccines to prevent. Some drugs that have been effective against previous viruses such as hydroxychloroquine (antimalarial), avigan (influenza), ritonavir (HIV prevention), etc. have been studied and tested for treatment of SARS-CoV-2.
