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.

  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.

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.

  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).
