简要总结
Aim of this prospective, observational, multi-centered, randomized study is to detect cardiovascular complications in patients after coronavirus infection.
The study will include 100 patients who underwent confirmed by laboratory tests COVID-19 infection (polymerase chain reaction (PCR) testing, enzyme-linked immunosorbent assay (positive result at least 1 time)) 1-3 months ago with the degree of lung lesion more than 25%, who were admitted to the University Clinical Hospital No. 4 of I.M. Sechenov First Moscow State Medical University.
The study consists of 4 periods:
- Screening for up to 6 months.
- Inclusion in the study, undergoing of identical laboratory and instrumental testing.
- Re-examination of patients. After 6 months from the initial examination (9 months after discharge from the infectious diseases department), patients will be re-examined.
4 Determination of end points, statistical data processing.
Estimated result of the study is to confirm or refute the hypothesis:
- As a result of the analysis of ECG and pulse wave data and comparison with echocardiography data, identify cardiovascular complications of COVID-19 infection.
- To determine the diagnostic significance of pulse wave parameters for assessing cardiovascular complications in patients with a history of COVID-19 infection (sensitivity, specificity, positive and negative predictive value).
- Identify correlations between pulse wave parameters and biochemical markers of endothelial dysfunction (endothelin-1).
- As a result of the analysis of exhaled air by the proton mass spectrometry, to identify markers of cardiovascular complications in patients after COVID-19 infection.
- As a result of a cardiorespiratory stress test, determine the respiratory and cardiovascular causes of dyspnea, exercise tolerance of patients after infection with COVID-19.

Aim of this prospective, observational, multi-centered, randomized study is to detect cardiovascular complications in patients after coronavirus infection.
The study will include 100 patients who underwent confirmed by laboratory tests Coronavirus Disease 2019 (COVID-19) infection (polymerase chain reaction (PCR) testing, enzyme-linked immunosorbent assay (positive result at least 1 time)) 1-3 months ago with the degree of lung lesion more than 25%, who were admitted to the University Clinical Hospital No. 4 of I.M. Sechenov First Moscow State Medical University.
The study consists of 4 periods:
- Screening for up to 6 months. Performed by a pulmonologist. Patients meeting the inclusion criteria are selected.
- Inclusion in the study. If the patient meets the inclusion criteria, a discussion about the nature of the study is held with the patient. Further, consent to participate in the study and to process personal data is obtained. After, the epicrisis from the COVID-19 infectious diseases department is analyzed.
Patients are provided with medical care in accordance with the standards approved by the Ministry of Health of the Russian Federation, and local acts of the institution in which the study is carried out.

结局指标
主要结局
Changes in the diastolic function of the right and left ventricles (compared with initial indicators)
时间窗: In 9 months after the recovery from COVID-19
Transthoracic echocardiography (EchoCG) will be performed to assess the heart structure and function: unidimensional (M-mode), two-dimensional (B-mode) and Doppler. Diastolic function of the left ventricle will be assessed using pulse-wave, constant-wave, and tissue Doppler studies. Maximum velocity of early (E peak) and late (A peak) diastolic filling, E/A ratio, time of blood flow deceleration of early left ventricular diastolic filling (DT) will be determined at simultaneous recording of aortic and transmitral blood flow in constant-wave mode, left ventricular isovolumic relaxation time (IVRT) - interval from the end of aortic to the beginning of transmitral blood flow.
Change in speed indicators on the heart valves (compared with initial indicators)
时间窗: In 9 months after the recovery from COVID-19
Transthoracic EchoCG will be performed to assess the heart structure and function: unidimensional (M-mode), two-dimensional (B-mode) and Doppler.
Changes in endothelin-1 in dynamics (compared with initial indicators)
时间窗: In 9 months after the recovery from COVID-19
This outcome will be assessed by taking blood samples from a peripheral vein

时间窗: In 9 months after the recovery from COVID-19
Transthoracic EchoCG will be performed to assess the heart structure and function: unidimensional (M-mode), two-dimensional (B-mode) and Doppler. Ejection fraction will be assessed according to BIPLANE, TAPSE.
