The review aims to present the chronological sequence of developing universal definitions of myocardial infarction, new ideas for improving the screening of post-infectious and sepsis-associated myocardial infarction (MI) (casuistic masks of myocardial infarction). The stages of the development of the common and global definition of myocardial infarction are outlined: 1 — by WHO working groups based on ECG for epidemiological studies; 2 — by the European Society of Cardiology and the American College of Cardio-logy using clinical and biochemical approaches; 3 — the Global Task Force consensus document of universal definition with subsequent classification of MI into five subtypes (spontaneous, dissonance in oxygen delivery and consumption; lethal outcome before the rise of specific markers of myocardial damage; PCI-associated; CABG- associated); 4 — review by the Joint Task Force of the above document based on the inclusion of more sensitive markers — troponins; 5 — the allocation of 17 non-ischemic myocardial damage, accompanied by an increase in the level of troponin; 6 — characteristic of the atrial natriuretic peptide from the standpoint of its synthesis, storage, release, diagnostic value as a biomarker of acute myocardial dama­ge; 7 — a clinical definition of myocardial infarction, presented in materials of the III Consensus on myocardial infarction 2017. The diagnosis of myocardial infarction using the criteria set in this document requires the integration of clinical data, ECG patterns, laboratory data, imaging findings, and, in some cases, pathological results, which are considered in the context of the time frame of the suspec­ted event. K. Thygesen et al. consider the additional use of: 1) cardiovascular magnetic resonance to determine the etiology of myocardial damage; 2) computer coronary angiography with suspected myocardial infarction. Myocardial infarction is a combination of specific cardio markers with at least one of the symptoms listed above. The formation of myocardial infarction can occur during/after acute respiratory infection. Causal relationships between these two states are established. Post-infectious myocardial infarction is strongly recommended to be individualized as a separate diagnostic entity. In sepsis, global myocardial ischemia with ischemic myocardial damage arises as a result of humoral and cellular factors, accompanied by an increase in troponins, a decrease in the ejection fraction of the left ventricle by 45 % and an increase in the final diastolic size of the left ventricle, the development of sepsis-associated multiple organ fai­lure, which is an unfavourable prognosis factor.

Aim. To assess the diagnostic value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in hemodialysis (HD) patients.Material and methods. A total of 80 patients over the age of 18 with an end-stage renal disease (ESRD) on HD were included in this study. NT-proBNP serum levels were measured for all patients in addition to traditional clinical and biochemical studies. Transthoracic echocardiography and bioimpedance spectroscopy using the Body Composition Monitor (BCM) device (Fresenius, Germany) were performed for all patients on HD. Patients were divided into two groups depending on the hydration status determined by BCM. Patients were also divided into three groups depending on the ejection fraction (EF) of the left ventricle: HF with reduced EF (less than 40%) (HFrEF), mid-range EF (from 40% to 49%) (HFmrEF), and HF with preserved EF (50% or more) (HFpEF). Three groups of patients were identified according to quartile level of NT-proBNP (<1095 pg/ml (n=20); 1095-4016 pg/ml (n=40); >4016 pg/ml (n=20).Results. The median of the NT-proBNP serum level was 2114,6 [1095; 4016] pg/ml. A significant increase in the NT-proBNP levels was found in HD patients with hyperhydration (p<0,05). Statistically significant differences were generally found between the concentration of NT-proBNP depending on the LVEF (n=80). However, in pairwise comparisons, significant differences were found only between the groups of patients with HFpEF and HFmrEF (p=0,02); a tendency to differences was revealed when comparing the groups of HFpEF and HFrEF (p=0,07). A proportional increase in the concentration of prohormone to the increase in systolic dysfunction was found while analyzing the median NT-proBNP, both among all patients and after separation into groups depending on the hydration status. A tendency to increase the frequency of new cardiovascular events, systolic and diastolic myocardial dysfunction in group of patients with prohormone increase was revealed.Conclusion. NT-proBNP serum levels in HD patients are significantly higher than the average population levels. A significant increase in the NT-proBNP levels was found in hemodialysis patients with hyperhydration. NT-proBNP should be used as an additional method for the diagnosis of heart failure on HD, including clarifying of the phenotype of heart failure depending on left ventricle EF. NT-proBNP high levels in patients on HD may be associated with a risk of developing cardiovascular events, systolic and diastolic myocardial dysfunction. It is necessary to use an examination algorithm for the differential diagnosis of heart failure and hyperhydration syndrome during dialysis: clinical examination, bioimpedansometry, transthoracic echocardiography, determination of serum NT-proBNP level.

Design Assessment

The purpose of the research was studying of clinical and diagnostic value of bronchial obstruction, hypoxemia, as well structural and functional condition of the left departments of heart in the patients with middle and severe degree of bronchial asthma. This research had prospective open design. Assessment of cardiac remodeling was carried out by means of the echocardiography with color Doppler mapping in period of exacerbation and after 12 months. Indicators of function of external respiration were estimated by means of the spirography and the bodyplethismography at the same periods. According to research data, it was revealed that with the severity of asthma is increasing the size of the left atrium and a decrease in the ratio of the AO/LA. The importance of early identification of a hypertrophy of a left ventricle in the patients with severe bronchial asthma is bound to the fre-quency of accompanying cardiac pathology and the correlation between hypertrophy of a left ventricle and the subsequent adverse clinical course of cardiovascular diseases. In patients with bronchial asthma parallel to the severity of the disease are formed changes of structural and functional state of myocardium of the left ventricle, causing diastolic dysfunction. The most significant risk factors in the formation of diastolic dysfunction of the left ventricle in patients with bronchial asthma are bronchial obstruction and hypoxemia.

Aim. To evaluate the informational and diagnostic significance of the myocardial Tei index.Patients and methods. The study assessed data of echocardiographic studies of 9,256 patients aged 1 month to 60 years, 1,350 healthy individuals, and 7,906 patients with various cardiovascular diseases with abnormal volume-capacitive characteristics of the heart (congenital heart defects, different types of cardiopathy, and hypertensive disease).Results. The cutting points of the normal values of the indicator were established. Data showed that the Tei index did not reflect changes in the pumping function of the left ventricle and did not depend on the contractility of the left ventricle (LV), but it had direct significant correlation with the left ventricular filling pressure, both in normal and pathological conditions. Correlation was more significant in adult patients.Conclusion. Normal values of the Tei index less than 0.5 were observed in more than 95% of practically healthy individuals of any age. The maximum sensitivity and specificity of the myocardial performance index was found in patients with restrictive and dilated cardiopathy and common atrioventricular connection.

Good Agreement

For years the separation of carcinoma and sarcoma and the subclassification of sarcomas has been based on the appearance of the tumor cells and their microscopic growth pattern and information derived from certain histochemical and special stains. Although this method of study has produced good agreement among pathologists in the separation of carcinoma from sarcoma, it has given less uniform results in the subclassification of sarcomas. There remain examples of neoplasms of different histogenesis, the classification of which is questionable because of similar cytologic and growth patterns at the light microscopic level; i.e. amelanotic melanoma versus carcinoma and occasionally sarcoma, sarcomas with an epithelial pattern of growth simulating carcinoma, histologically similar mesenchymal tumors of different histogenesis (histiocytoma versus rhabdomyosarcoma, lytic osteogenic sarcoma versus rhabdomyosarcoma), and myxomatous mesenchymal tumors of diverse histogenesis (myxoid rhabdo and liposarcomas, cardiac myxoma, myxoid neurofibroma, etc.)
