One of the dangerous complications of COVID-19 is blood clotting, which must be monitored after an illness. Russian transfusiologist Andrei Zvonkov spoke about this in an interview with Sputnik radio station.
According to Zvonkov, an INR (international normalized ratio) test must be taken within at least six months, which will show the state of the blood coagulation system.
If the parameter is less than 1.5, then it is necessary to take drugs that thin the blood and reduce clotting. If more than 1.8-1.85 - everything is in order, blood clotting will be normal. “But if the parameter is more than 2, then you have drunk too many thinning drugs, you need to see a doctor and cancel or reduce the dosage,” Zvonkov said.
He explained that a blood test should be taken every six months if the person is not at risk. It includes the elderly, people with arrhythmias, coronary heart disease, chronic inflammatory diseases, smokers, people with varicose veins, overweight, obesity, diabetes mellitus. They need to be regularly tested for at least the blood coagulation system to avoid the risk of blood clots and thrombosis.
Earlier, the doctor Maryana Lysenko said that patients after coronavirus have a multisystem inflammatory syndrome. This is a complex of problems associated with the body's autoimmune aggression directed at itself. Target organs may be affected, including the kidneys or heart.
