Brief Summary:
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:
1. Screening for up to 6 months.
2. Inclusion in the study, undergoing of identical laboratory and instrumental testing.
3. 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:
1. As a result of the analysis of ECG and pulse wave data and comparison with echocardiography data, identify cardiovascular complications of COVID-19 infection.
2. 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).
3. Identify correlations between pulse wave parameters and biochemical markers of endothelial dysfunction (endothelin-1).
4. 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.
5. 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.
Detailed Description:
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:
1. Screening for up to 6 months. Performed by a pulmonologist. Patients meeting the inclusion criteria are selected.
2. 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.
Patients eligible for inclusion will undergo the following investigations:
* Anamnesis and complaints collection; physical examination;
* Assessment of the quality of life and psycho-emotional status using the Short Form-36 (SF36) and Hospital Anxiety and Depression Scale (HADS) questionnaires, as well as the six-minute walk test;
* General and biochemical blood tests , urine analysis, , determination of biochemical markers of endothelial dysfunction (endothelin-1) in the blood;
* Electrocardiography, a flow mediated dilatation procedure for endothelial function assessment, transthoracic echocardiography to identify the structural and functional features of the myocardium, spiroergometry to determine the patient's oxygen consumption.
* Electrocardiogram (ECG) in one lead with an assessment of the pulse wave using a portable cardiac monitor "CardioQvark"
* The analysis of exhaled air will be performed using the Compact proton mass spectrometer (PTR-MS) manufactured by Ionicon (Austria).
3. 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, In the interval between the initial and repeated examinations, the condition of all patients will be monitored, for this it is expected to make phone calls, the frequency of 1 time per month.
4 Determination of end points, statistical data processing. The statistical processing will be performed using the Python Software Foundation version 3.8 for Windows (Delaware, USA).
Estimated result of the study is to confirm or refute the hypothesis:
1. As a result of the analysis of ECG and pulse wave data and comparison with echocardiography data, identify cardiovascular complications of COVID-19 infection.
2. 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).
3. Identify correlations between pulse wave parameters and biochemical markers of endothelial dysfunction (endothelin-1).
4. 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.
5. 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.
