The aim of the work is to assess the features of the clinical course of AF against the background of COVID-19 according to the registry of cardiac patients. Materials and methods. The work involved 36 people suffering from AF (mean age was 67.89±3.39 years). There were 2 groups: main and control. The main group consisted of patients suffering from AF and having had a coronavirus infection - 14 people (mean age - 67.23 ± 3.36 years), the control group - patients suffering from CVD without a history of COVID-19 - 12 people (mean age - 68, 66±3.43 years). In the main group, most of the patients had a permanent form of AF - 8 people (57.14%); persistent form - 4 people (28.57%); paroxysmal form - 2 people (14.29%). In the control group, 7 people (58.33%) had a permanent form of AF, persistent - 4 people (33.33%) and paroxysmal - 1 person (8.34%), respectively. In the work, a survey was conducted of patients on complaints that bother them after suffering a COVID-19 infection. The data obtained were analyzed using the STATISTICA program. The results were recognized as significant at p<0.05. Results. Thromboembolic complications were significantly (p<0.05) more often verified among patients of the 1st group (in 14.29% - with a permanent form of AF; in 21.43% of cases - with paroxysmal and persistent forms of AF). Patients who underwent COVID-19 more often complained of palpitations (in 78.57% of cases), interruptions in the work of the heart (in 64.29% of cases), shortness of breath (in 64.29% of cases), general weakness (in 78 .57% of cases). In addition, they were more likely to experience feelings of anxiety and fear. Conclusion. The clinical course of AF worsens significantly after a COVID-19 infection, which is manifested by an increase in the number of complaints and an increase in the incidence of thromboembolic complications.
