About this study

Study rationale: to evaluate clinical and prognostic relevance of microvascular dysfunction, coronary flow reserve and cardioprotective effects of iv administration of esmolol in patients with myocardial infarction. First substudy is an open randomized trial evaluating the efficacy and safety of early intravenous administration of esmolol in patients with acute ST-segment elevation myocardial infarction (MI) and relative contraindications to administration of other intravenous β1-adrenergic blocker (metoprolol etс.). Сomparison group will include patients who have not received intravenous β1-adrenergic blocker. Secondary outcome in this substudy is the degree of microvascular obstruction and infarct size according to MRI with gadolinium delayed enhancement. Second substudy examines the quantitative parameters of coronary physiology in patients with MI and multivessel disease. Changes of coronary physiology measurements over time ((iFR, Pd/Pa, FFR, delta FFR, gradient FFR per time unit (dFFR(t)/dt), pullback pressure gradient (PPG)) measured in the infarct-related artery and in non-infarct-related arteries with diameter stenosis of 50-85% immediately after the completion of a primary percutaneous coronary intervention and during a second hospitalization (30-45 days after STEMI) will be evaluated. The comparison changes of coronary physiology over time with presence of an MVO and infarct size determined by MRI. The model of calculating coronary flow reserve (CFR) based on tri…
