“…Дизайн упомянутого исследования не учитывал наличие или отсутствие хронических ССЗ, тогда как вегетативная регуляция сердечного ритма существенно различается у пациентов с COVID-19 без сопутствующей сердечно-сосудистой патологии и у больных с АГ и COVID-19. В другой работе было показано, что тонус симпатического компонента ВНС выше у пациентов с COVID-19 и АГ в сравнении с больными COVID-19 без сопутствующих ССЗ [41]. Согласно дизайну исследования Сказкиной В. В. и др., тяжелое течение COVID-19 было критерием исключения.…”

This review considers the risk factors for arterial hypertension (AH) progression, obstructive sleep apnea syndrome (OSAS) and novel coronavirus infection (COVID-19) as potential variables for the prognostic models of estimating the probability of destabilization of the mentioned conditions. The most published studies consider AH and OSAS as the risk factors influencing the course of COVID-19, while moderate and mild COVID-19 can be destabilizing factor regarding to AH and OSAS. In addition, COVID-19, AH and OSAS are interrelated with sleep quality. The worsening of sleep quality often can be both a consequence of these diseases and a factor aggravating their course, and also can cause the increased vulnerability to acute diseases. An increased body mass index is a universal risk factor for many diseases and clinical conditions, and the monitoring of body mass increases the degree of the control of the diseases associated with obesity. In addition, the worsening of sleep quality can be both a consequence of any of above-mentioned conditions and a factor aggravating their course. Also, a promising direction for improving prognostic models is the analysis of autonomic dysfunction in patients.

“…Отдельные параметры ВРС могут служить прогностическими критериями характера течения и осложнений заболевания в ранний и отдаленный периоды ОИМ [17]. Особенности ВРС у пациентов с ОИМ, перенесших COVID-19, недостаточно изучен, в связи с чем оценка параметров ВРС у больных ОКС, перенесших COVID-19, представляется крайне актуальной задачей клинической кардиологии [18].…”

Aim. To compare heart rate variability parameters in patients after a coronavirus disease 2019 (COVID-19) with acute ST elevation myocardial infarction (STEMI) during the inhospital and post-hospital periods.Material and methods. A total of 140 patients with STEMI were divided into 2 groups: I — patients with STEMI who had COVID-19 (n=52) in the period of 1,5-6 months before acute coronary syndrome, II — comparison group (n=88), which included patients with STEMI without prior COVID-19. All patients underwent infarct-related artery stenting within the first 24 hours from the onset. Heart rate variability (HRV) parameters were determined for all patients on days 2-3 and days 9-11 and 6 months after the hospitalization for STEMI.Results. Patients in group I showed more pronounced changes in HRV indicators on days 2-3 of STEMI: RMSSD (root square of successive RR intervals) by 21% (p=0,026), variations (Var) (the difference between the minimum and maximum RR intervals) by 33% (p=0,013), VLF (total very low-frequency HRV) by 7% (p=0,009) were higher, and HF (highfrequency HRV) by 40% (p=0,003), pNN50% (ratio of the number of consecutive RR interval pairs differing by >50 ms to the total number of RR intervals) by 66% (p=0,038) were lower than in the control group, respectively. On days 9-11 of the disease in patients with a history of STEMI and COVID-19, in contrast to the control group, there was a more pronounced increase in the SDNN (standard deviation of RR intervals) by 46% (p=0,005), VLF by 42% (p=0,031), whereas in the control group there were an increase of only 22% (p=0,004) and 11% (p=0,022), respectively. The HF value in the main group increased by 25% (p=0,007), while in the control group it decreased by 19% (p=0,030). Six months after STEMI in the main group, the RMSSD decreased by 19% (p=0,009), Var by 16% (p=0,041), VLF by 30% (p=0,025), LF (low-frequency component HRV) by 11% (p=0,005), while the control group these parameters decreased by 20% (p=0,006), 21% (p=0,001), 9% (p=0,011), and 7% (p=0,016), respectively.Conclusion. In patients with STEMI and prior COVID-19, the initial HRV values differ from similar HRV parameters in patients with STEMI without prior COVID-19. In the hospital and post-hospital periods, the changes of HRV in patients with and without COVID-19 are multidirectional as follows: pronounced sympathetic hyperactivity predominates, and slower recovery of HRV in patients after COVID-19 predominates.
