Evaluation of the Effect of Long-term Lipid-lowering Therapy in STEMI Patients With Coronavirus Infection COVID-19
- Conditions
- STEMICovid19NSTEMI
- Interventions
- Drug: Atorvastatin-Ezetimibe
- Registration Number
- NCT04900155
- Lead Sponsor
- Penza State University
- Brief 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.
