MOSCOW, 4 Mar - PRIME. Those who have undergone COVID-19 need to monitor the state of the blood coagulation system for some more time, transfusiologist Andrei Zvonkov advised in an interview with Sputnik radio. According to him, a clotting disorder is one of the most serious complications of this disease.
The doctor noted that this can only be done with the help of tests - it is advisable to periodically take an analysis for the INR for at least six months, that is, the international normalized ratio. It shows the state of the blood coagulation system: if the parameter is less than 1.5, then this is alarming, and you need to take drugs that thin the blood and reduce clotting. If more than 1.85 1.85, then this is normal blood clotting and a minimum risk of developing blood clots. "If the parameter is more than 2, it means that you have drunk too many thinning drugs, you need to consult a doctor and cancel or reduce the dosage," Zvonkov said.
He also explained how often you need to take a blood test for healthy people and those who are at risk.
"Everything should be within reasonable limits. Periodically, you can take blood tests, once every six months, if you do not belong to the risk group. The risk group is the elderly, people suffering from arrhythmias, coronary heart disease, some kind of chronic inflammatory diseases, smokers, people with varicose veins, overweight, obesity, diabetes mellitus. All these are aggravating situations. Therefore, you just need to regularly take tests at least for the blood coagulation system to avoid the risk of blood clots, thrombosis, "said the doctor.
