Clinical Trial Summary
It is planned to include 200 patients hospitalized with primary myocardial infarction with
and without ST segment elevation (STEMI or NSTEMI) in combination with COVID-19 within the
first 15 days from the disease onset. The total follow-up period is 96 weeks.
Hypotheses:
1. An integrated approach in assessing myocardial contractility, regulation of the heart
and the structural and functional state of arteries will make it possible to more
accurately assess the heart pumping function; explain the mechanisms of the relationship
between left ventricular (LV) contractile function and its volumetric indices; to study
the mechanisms of ventriculo-arterial coupling and the influence of autonomic
regulation, the role of markers of the sudden cardiac death (late ventricular
potentials, pathological turbulence of the heart rate, dispersion of the QT interval).
2. In patients who have had myocardial infarction in combination with the new coronavirus
infection SARS-CoV-2 (COVID-19), long-term highly effective lipid-lowering therapy,
regardless of the drugs prescribed, has an antiarrhythmic effect and has a beneficial
effect on the autonomic regulation of the heart rate. Highly effective lipid-lowering
therapy leads to an improvement in LV contractility and structural and functional
properties of the large arteries.

10. Flow-mediated vasodilation
11. Six-minute walk test

13. Adherence to Treatment: Counting remaining pills and completing the Morisky-Green
Questionnaire

15. Assessment of physical activity: International Questionnaire On Physical Activity - IPAQ
16. Hospital Anxiety and Depression Scale (HADS)
Description:
It is planned to include 200 patients hospitalized in the cardiology department of the "Penza
Regional Clinical hospital Burdenko" with a STEMI diagnosis in combination with COVID-19.
Patients with STEMI and NSTEMI will be included in the study within the first 15 days from
the disease onset. The total follow-up period is 96 weeks.
Primary goals:
- achieving the target level of low-density lipoprotein cholesterol (LDL-C) on the
background of lipid-lowering therapy as monotherapy with atorvastatin or combined
treatment with atorvastatin plus ezetimibe;
- decrease in the incidence of major coronary events - percutaneous coronary interventions
(PCI) / coronary artery bypass surgery (CABG) for a new case of coronary
atherosclerosis, hospitalization for unstable angina or recurrent myocardial infarction;
- reduction of the frequency of life-threatening arrhythmias and markers of the risk of
sudden cardiac death according to the data of long-term ECG monitoring;
- increase in myocardial contractility by improving the deformation characteristics of the
peri-infarction zone.
Secondary goals:
1. Assess the effect of long-term effective lipid-lowering therapy:
- indicators of global and regional myocardial deformation, depending on the degree
of of coronary blood flow restoration according to TIMI scale;
- systolic and diastolic LV function in the presence of initial disturbances or the
absence of negative dynamics of these indicators with normal initial values;
- on clinical and diagnostic criteria for the development or progression of heart
failure (HF);
- on the dynamics of myocardial ischemia episodes according to the data of long-term
electrocardiography (ECG) monitoring;
- for the immediate and long-term prognosis of patients;
- on the structural and functional properties of large arteries.
2. Assess the dynamics of biochemical parameters against the background of double and
monotherapy with lipid-lowering drugs.
3. Assess the safety of treatment.
4. Assess the impact on the patient's well-being and quality of life.
5. Assess therapy compliance
6. Conduct a comparative analysis of the prognostic value of markers of myocardial
electrical heterogeneity, obtained from the data of long-term and 24-hour ECG
monitoring.
7. To determine the effect of markers of electrical instability and autonomic regulation of
cardiac activity, obtained during long-term ECG monitoring in patients at different
times after myocardial infarction, on the short-term and long-term prognosis.
8. Development of a multivariate model that takes into account the parameters of
electrophysiological heterogeneity and the main indicators of the cardiovascular system
condition (data of echocardiography, blood vessels ultrasound, laboratory test), which
allows predicting the development of repeated cardiac events.
Methods and variables
1. Office blood pressure
2. 12-lead ECG
3. Coronary angiography. Percutaneous coronary intervention
4. Chemistry blood test The lipid profile: total cholesterol (TC), high-density lipoprotein
cholesterol (HDL-C), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C),
non-HDL. Alanine aminotransferase (ALT), aspartat aminotransferase (AST), creatine
phosphokinase (CPK), glucose, C-reactive protein (CRP), brain natriuretic peptide (BNP),

determination of immunoglobulins to SARS-CoV-2.
5. 2D and 3D transthoracic echocardiography is performed with Vivid GE 95 Healthcare (USA).
The biplane ejection fraction is determined by the Simpson method, 3D ejection fraction,
EDV (end-diastolic volume), ESV (end-systolic volume) and their indexed parameters in 2D
and 3D mode. Left ventricular myocardial mass index (LVMI), LA volume. Myocardial
deformity is analyzed using specialized software - EchoPac Software Only (General
Electric Co., 2018)
6. Multi-day 3-lead ECG monitoring with assessment of the parameters of myocardial
electrical instability.
7. Ultrasound of common carotid arteries using high-frequency RF signal technology will be
carried out in B-mode on the MyLab 90 device (Esaote, Italy) by the following
indicators: IMT - thickness of the intima-media, loc Psys - local systolic pressure in
the carotid artery, loc Pdia - local diastolic pressure, P (T1) - pressure at a local
point, stiffness indices β and α, DC - coefficient transverse distensibility, CC -
transverse compliance coefficient, Aix - augmentation index, AR - amplification
pressure, PWV - local pulse wave velocity in the carotid artery.
8. Applanation tonometry The SphygmoCor device (AtCor Medical, Australia) includes two
software. The first allows to record indicators of central aortic pressure: systolic
aortic pressure - SBPao, diastolic - DBPao, pulse pressure - PPao, mean hemodynamic
pressure - MBPao. The PWV (pulse wave velocity) software is used to analyze the PWV in
the aorta (cfPWV).
