PRACTICAL ASPECTS OF EVALUATING THE EFFECTIVNESS OF THE INDUSTRIAL ENTERPRISE MANAGEMENT SYSTEM

It is necessary to differentiate when considering the effectiveness of the organization’s management system: the organizational structure of management as a formalized descriptive scheme for the distribution of tasks and responsibilities and the organizational management system as  approaches, methods used in the relationship between the object and the subject of management. The article provides assessment tools in the case of considering the efficiency of the functioning of the managed system as a whole or its elements: comparison of the market value of the organization and the book value of its assets or equity; comparison of the amount of revenue, net profit, industry average profitability indicators and indicators of a particular organization; comparison of non-financial indicators, for example, market share, labor productivity, employee satisfaction, etc. It is shown that index and coefficient methods are used to assess the effectiveness of management in the narrow sense as the effectiveness of the actual management activity. The method for assessing the effectiveness of an organization’s management system is proposed. The results of practical research on the proposed method are shown on the example of domestic and foreign industrial enterprises

Evolution of chronic heart failure syndrome in a patient with myocardial infarction and complex rhythm disturbances

Abstract: today the problem of chronic heart failure as a complication of myocardial infarction and other cardiovascular diseases continues to be relevant, due to the increase in the prevalence of heart failure, especially the severe stage of heart disease and the main causes of deaths of this cohort of patients. The article presents a clinical case of chronic heart failure syndrome with complex rhythm disturbances in the patient against the background of the transferred transmural myocardial infarction and hypertension. The authors demonstrated that after a thorough assessment of the risk and benefit of various treatment methods, the therapeutic and surgical tactics of management of the patient in this clinical situation were correctly chosen, which allowed not only to prolong life, but also to improve the quality of life of the patient. Thus, in this clinical case, we show the importance of personalized therapy in the progression of chronic heart failure syndrome in patients with combined cardiovascular disease.На сегодняшний день проблема хронической сердечной недостаточности, как осложнение инфаркта миокарда и другой сердечно-сосудистой патологии продолжает оставаться актуальной, связно это с увеличением распространенности сердечной недостаточности, особенно тяжелой стадии поражения сердца и основными причинами летальных исходов данной когорты пациентов. В статье представлен клинический случай синдрома хронической сердечной недостаточности со сложными нарушениями ритма у пациента на фоне перенесенного трансмурального инфаркта миокарда и гипертонической болезни. Авторами продемонстрировано, как после тщательной оценки риска и пользы различных методов лечения была правильно подобрана терапевтическая и хирургическая тактика ведения больного в данной клинической ситуации, что позволило не только продлить жизнь, но и улучшить качество жизни пациента. Таким образом, данным клиническим случаем мы показываем важность персонифицированной терапии при прогрессировании синдрома хронической сердечной недостаточности у пациентов с сочетанной сердечно-сосудистой патологией

NEUROPHYSIOLOGICAL EVALUATION OF THE EFFECTIVENESS OF EARLY CAROTID ENDARTERECTOMY IN ATHEROTHROMBOTIC STROKE

INTRODUCTION. At present, the advantages of surgical treatment over conservative methods in patients with hemodynamically significant stenosis of the carotid arteries are actively discussed. Nowadays, the main discussion issues are the time from the beginning of the stroke to the operation and the criteria for selecting patients for surgical intervention. In recent years, neurophysiological methods for studying spontaneous and evoked brain activity, which are able to identify functional disorders that have important prognostic significance, have become the most relevant.OBJECTIVE. To study the dynamics of spectral-coherent parameters of EEG and somatosensory evoked potentials in patients with ischemic atherothrombotic stroke of different severity, who were performed carotid endarterectomy on the heart attack side in an acute period.METHODS AND MATERIALS. We examined 105 patients with ischemic stroke who underwent carotid endarterectomy in the acute period, analyzed the dynamics of spectral, coherent characteristics of EEG and amplitude-latency parameters of somatosensory evoked potentials in the postoperative period.RESULTS. The dynamics of power spectra, intra-hemispheric EEG, latency and amplitude of somatosensory evoked potentials and clinical parameters were compared.CONCLUSION. It is shown that significant suppression of alpha activity power on the side of both hemispheres, decrease of intra-hemispheric coherence and amplitude of N20-P23 on the side of clinically intact hemisphere in the period up to 3 weeks after surgery determines a longer recovery of neurological deficit in the postoperative period

The influence of factors on five-year outcomes after acute coronary syndrome

Aim. To identify the factors of long-term adverse prognosis of patients with acute coronary syndrome as a result of five-year follow-up.Material and methods. The study included 280 patients with ACS hospitalized in the 1st cardiology Department of the Novosibirsk municipal CLINICAL hospital № 1 in 2010-2011. The study cohort included 145 patients with ACS (107 men and 38 women), 135 patients with ACS (93 men and 43 women). The average age of men was 56,3±5,2, women 52,1±5,3 years. The criteria of the European society of cardiology (2015, 2017) were used for the diagnosis of ACS. For five years, all patients included in the study were contacted through communication and annual medical examinations, to which patients were invited to the clinic. The examinations included the following clinical and instrumental examinations: clinical examination, electrocardiography, Holter monitoring of electrocardiogram, echocardiography, lipid profile, inflammatory cytokines and molecular genetic parameters. In the study, a mathematical model for predicting five-year outcomes Oxpt and Oxbt. Results. Five-year observation allowed using the constructed mathematical model to determine not only the place of each factor in the cardiovascular prognosis, but also to assess how the role of these prognostic markers changes over time. Conclusion. The use of a mathematical model for predicting long-term adverse outcomes of ACS allows to assess the value of specific risk factors and predictors, respectively, makes a significant contribution to the optimization of secondary prevention and personalized approach to treatment. At the same time, the influence of the identified predictors weakens in proportion to the increase in the number of years from a vascular accident. Thus, the identified risk factors have the maximum impact in the first year after ACS, in subsequent years, the role of these factors is reduced, which is probably due not only to the importance of the factors themselves, but also to the addition of other risk factors to the overall picture of the disease of patients. Nevertheless, the use of this model is necessary to solve the problem of reducing cardiovascular risk

Genetic markers of risk for ST-elevated myocardial infarction

Aim. To identify genetic markers of risk for ST-elevated myocardial infarction (STEMI).Material and methods. The study included 210 patients (119 men, 91 women) with STEMI, hospitalized from December 21, 2016 to June 16, 2017 The average age of men was 55,5±9,5 years, women — 57,5±9,1 years. The diagnosis of STEMI was verified according to the criteria of the European Society of Cardiology (2015, 2017). During hospitalization, patients underwent clinical and instrumental examination, stipulated by medical care standards and clinical guidelines We also conducted a genetic study of single nucleotide polymorphisms (SNPs), which showed their association with the risk of coronary artery disease (CAD) and acute myocardial infarction (AMI) according to the GWAS: rs2820315 of the LMOD1 gene (Leiomodin 1, mapped on chromosome 1), rs9349379 of the PHACTR1 gene (regulator 1 of actin and phosphotase, localized on chromosome 6p241), rs867186 of the PROCR gene (Protein C receptor, located on chromosome 20q11.22), rsi1799883 of the FABP2 gene (Fatty acid-binding protein 2, located on chromosome 4q26). Statistical data analysis was performed using the SPSS 170.5 software package and authorial odds ratio (OR) calculator.Results. Carriage of the CC genotype of rs2820315 polymorphism of the LMOD gene is associated with an increased risk of STEMI by 1,87 times (95% CI 1,2862,722, p=0,016). Carriers of the CT genotype of rs2820315 polymorphism have a reduced risk of STEMI (OR 0,633; 95% CI 0,436-0,918, p=0,016).Conclusion. In order to identify risk groups for STEMI development, the study of the rs2820315 polymorphism of the LMOD gene is recommended. This will define the high-risk group for STEMI for developing of personalized programs for primary and secondary prevention of cardiovascular events in practical health care, which will contribute to reducing of STEMI mortality

Genetic predictors of five-year outcomes of acute coronary syndrome

Aim. To determine the genetic predictors of five-year outcomes in patients with acute coronary syndrome (ACS).Material and methods. The study included patients admitted to the City clinical hospital № 1 (CCH №1) in Novosibirsk with a diagnosis of ACS in the period 2010-3 2011 (n=280). All patients were examined in accordance with clinical guidelines and standards of care, genetic markers were assessed. Genotyping included determination of single nucleotide polymorphisms (SNPs), confirming its association with the development of the ACS according to the results of an international genomeassociated studies: rs1376251, rs4804611, rs 1333049, rs619203, rs10757278, rs2549513, rs499818, rs17465637. All patients are kept in touch from the moment of initial contact to the present time, with the help of available means of communication and annual examinations in order to assess the end points. “End points” included: repeated nonfatal myocardial infarction (MI), hospitalization for myocardial ischemia, re-revascularization or chronic heart failure (CHF), nonfatal acute cerebrovascular accident (NACA), cardiovascular death.Results. We revealed SNPs, which play a role in predicting long-term outcomes of ACS: rs10757278, rs 4804611, rs 1333049, rs 2549513. The genotype of rs2549513 as 2,9-fold (95% CI 1,06-8,03; p=0,041) increases the risk of unfavorable long-term prognosis in the subgroup of men older than 55 years. The AA genotype rs10757278 and GG genotype rs1333049 are associated with a favorable long-term prognosis (OR=0,47, 95% CI 0,23-0,96; p=0,042 and OR=0,41, 95% CI 0,22-0,78; p=0,049, respectively) in the group of patients older than 55 years. For the GG genotype rs1333049 association was characteristic only for women. The AA genotype rs4804611 is associated with a favorable outcome of ACS at the age of 55 years (OR=0,036, 95% CI 0,14-0,96; p=0,053), significant differences were obtained in the group of men (p=0,36).Conclusion. The use of identified genetic predictors to assess the risk of five-year outcomes will strengthen a personalized approach to patients and, together with conventional prevention measures, will reduce cardiovascular mortality
