The purpose of the study was to identify factors characterizing a decrease in LV global systolic function in patients with ST-segment elevation myocardial infarction (STEMI) after revascularization using cardiac magnetic resonance imaging (MRI)-based ischemic injury pattern and laboratory parameters sensu left ventricular global systolic function. A total of 109 STEMI patients were examined. The patients underwent contrast-enhanced cardiac MRI with a 1.

First Observation of Neutral Bremsstrahlung Electroluminescence in Liquid Argon.

A recent discovery of additional mechanism of electroluminescence (EL) in noble gases due to the neutral bremsstrahlung (NBrS) effect led to a prediction that NBrS EL should be present in noble liquids as well. A theoretical model of NBrS EL in noble liquids was developed accordingly in the frameworks of Cohen-Lekner and Atrazhev. In this work, we confirm this prediction: For the first time, visible-range EL has been observed in liquid argon at electric fields reaching 90  kV/cm, using gas electron multiplier (GEM) and thick GEM structures.

[Non-compact right ventricular myocardium - diagnostic and clinical features: A review].

Non-compact right ventricular myocardium is a rare type of cardiomyopathy, it usually results from arrested myocardial development during embryogenesis. This disease can be characterized by excessive prominent trabeculations and deep inter-trabecular recesses in the ventricular wall. It might be a component of biventricular non-compact cardiomyopathy or an isolated form.

Prediction of Adverse Post-Infarction Left Ventricular Remodeling Using a Multivariate Regression Model.

Background. In order to provide personalized medicine and improve cardiovascular outcomes, a method for predicting adverse left ventricular remodeling (ALVR) after ST-segment elevation myocardial infarction (STEMI) is needed. Methods.

Diagnosis of coronary artery rethrombosis after effective systemic thrombolytic therapy in patients with ST-segment elevation myocardial infarction.

The aim of the study was to evaluate the diagnostic significance of ST-segment re-elevation episodes registered with telemetric ECG monitoring in patients with ST-segment elevation myocardial infarction (STEMI) treated with thrombolytic therapy (TLT). The study included 117 patients with STEMI following effective TLT. The elective coronary angiography followed by percutaneous coronary interventions was performed in the interval from 3 to 24 hours after a successful systemic TLT.

Relationship between electrical myocardial instability and postinfarction remodeling in patients with ST-segment elevation myocardial infarction.

Aim      To study the clinical value of markers for myocardial electrical instability in combination with echocardiographic parameters for predicting the risk of cardiovascular complications (CVC) in the postinfarction period.Material and methods  This study included 118 patients with ST segment elevation myocardial infarction (STEMI) and hemodynamically significant stenosis of one coronary artery. A percutaneous coronary intervention (PCI) with stenting of the infarct-related artery was performed for all patients.

Early Predictors of Heart Failure Progression in Patients After Myocardial Infarction.

Aim      To identify early predictors for progression of chronic heart failure (CHF) in patients with ST-segment elevation myocardial infarction (STEMI).Material and methods  The study included 113 patients with STEMI aged 52 (95 % confidence interval, 36 to 65) years. 24-h ECG monitoring was performed with assessment of ventricular late potentials, QT dispersion, heart rhythm turbulence (HRT), and heart rhythm variability (HRV); XStrain 2D echocardiograpy with determination of volumetric parameters, myocardial strain characteristics and velocities; and measurement of brain natriuretic peptide (BNP) concentrations.

[The myocardial infarction size measuring using modern methods].

An accurate quantitative assessment of myocardium necrosis area and the viable zone (stunned and hibernating) in patients with myocardial infarction is crucial for the preoperative patient selection and predicting the cardiac surgery effectiveness. Currently, researchers and clinicians are most interested in the problem of determining the viable myocardium zone. However, only the necrosis zone area directly correlates with the patients prognosis and determines the heart pathological remodeling processes.

A New Approach to Evaluating the Pumping Function of the Heart by the Myocardial Work.

The function of left ventricular (LV) contractility consists of two aspects, the force of myocardial contraction, which provides a sufficient pressure gradient to open the heart valves, and deformation, which determines the actual cardiac output [1, 2]. The relationship between the characteristics of LV deformation and LV volume parameters remains poorly understood. The LV work may reflect the dependence between the volume and deformation characteristics of the left ventricle.

Use of the Speckle tracking method for determining global parameters of heart contractility in healthy individuals.

The speckle tracking method allows one to quantify the temporal and spatial characteristics of myocardial contraction. Importantly, it does not depend on a scanning angle and allows one to record the movement of speckles in 2D mode in any direction, unlike tissue Doppler imaging. This examination is non-invasive, safe for patients, and economically more beneficial in comparison with other modern methods of assessing heart contractility: MRI and scintigraphy.
