Journal of Anatomy and Histopathology, Год журнала: 2020, Номер 9(3), С. 16 - 21

Опубликована: Окт. 10, 2020

The article highlights peculiarities of localization myocardial bridges. It is believed that the coronary arteries and their branches are located in subepicardial tissue. However, some researchers describe cases intramural sections. Myocardial bridges – a set fibers ventricular myocardium over certain area branch artery - represent variants such localization. aim study was to establish patterns macroscopic anatomy topography investigating anatomical sections human heart adult elderly people. Material methods. involved 65 formalin-fixed sample preparations people who died conditions were not associated with diseases. authors measured transverse longitudinal dimensions complex heart, calculated transverse-longitudinal index. Subepicardial vessels prepared without prior injection. number main counted length measured. type blood supply determined according three-member classification, depending on source discharge posterior interventricular branch. Results. observed 44 (67.6%) preparations. As rule, they left (91.5%). They typically proximal half anterior sulcus. ranged from 2.5 64 mm (Me = 13 mm).

Predictors of recurrent cardiovascular events in patients with a single-vessel coronary artery disease after ST-segment elevation myocardial infarction

Rational Pharmacotherapy in Cardiology, Год журнала: 2023, Номер 19(4), С. 331 - 340

Опубликована: Сен. 7, 2023

Aim . To determine the predictors of recurrent cardiovascular events in patients after ST-segment elevation myocardial infarction (STEMI) and hemodynamicallysignificant stenosis only infarct-related coronary artery. Material methods The present study involved 151 with STEMI. mean age was 51 (95% confidence interval (CI), 41–61 years) years. One inclusion criteria significant exclusively All underwent a 24-hour Holter electrocardiography (ECG) monitoring analysis heart rate turbulence (HRT), variability (HRV), ventricular late potentials chronotropic load; two-dimensional (2D) echocardiography volumetric parameters left ejection fraction; determination brain natriuretic peptide (BNP). follow-up duration 144 weeks. Repeated (acute failure, revascularization, repeated infarction, death) were analyzed as endpoints. Two groups identified depending on event endpoints: “RE” group — 26 (17.2%) registered cardiac events, “ST” 125 (82.8%) without stable post-infarction period. Results Initial BNP values lower (p48=0.0035, p96=0.004, p144=0.001). intergroup differences demonstrate higher concentration levels both initially (p=0,001) at 96th week (p=0,04). Left fraction 144th contrast to group: 48,9% (44,7-53,2) vs 44,2% (38,5-49,9) (p=0,009). Pathological HRT also significantly (p=0,003) by (p=0,007), while HRV demonstrated low initial slow tendency restoration. There following risk factors for period: weight relative (RR), 1.21 CI, 1,01-1,46) (p=0,03); body mass index RR, 0,56 0,325-0,96) (p=0,046); load 1,03 1,02-1,12) (p=0,04); 1,012 1,003-1,08) (p=0,01); end-systolic dimension (ESD) 1,04 1,01-1,13) (p=0,36).

Background: Internal diseases pose a significant public health concern due to their prevalence and impact on premature mortality disability. This study investigates the role of internal in morbidity structure Republic Kazakhstan’s population, focusing period from 2019 2021. Objective: The primary objective this is assess dynamics among adult population Kazakhstan during 2019-2021. Methods: We conducted comprehensive analysis medical records healthcare facilities across for years focused cardiovascular system, endocrine metabolic disorders, respiratory gastrointestinal tract, urinary system. Epidemiological indicators, including rates morbidity, were calculated each disease category using official data same period. Results: Our findings indicate noteworthy increase Diseases system most prevalent, with arterial hypertension coronary heart being particularly pressing concerns. Diabetes mellitus thyroid abnormalities common organ diseases. Among diseases, bronchitis had highest prevalence, followed by tracheitis, bronchial asthma, pneumonia. Additionally, tract increased 3% over two years. Conclusion: underscores urgent need effective prevention management Kazakhstan. increasing all leading categories highlight

Immunological indexes for assessing parameters of cardiovascular system in athletes of different qualification

Medical Immunology (Russia), Год журнала: 2023, Номер 25(6), С. 1423 - 1430

Опубликована: Окт. 17, 2023

Timely diagnosis and prevention of cardiovascular diseases is based on markers that detect changes in the athlete’s body at an early stage disease. To implement this task, it important to use novel laboratory techniques. We have carried out a comparative determination immunological markers, specific antibodies angiotensin, bradykinin, histamine, dopamine, serotonin functional indicators system athletes various qualifications. The object study included Russian national teams who underwent in-depth examination (IME) as part medical survey. participants were divided into groups depending sport arts Representatives group “Cyclic sports” without category 30 people 29 qualified (1 st step, Candidate Master, Master Sports, etc.). “Combat consisted 32 31 with qualifications similar those indicated above. Athletes “Speed-strength” sports are represented by parameters analysis heart rate, systolic blood pressure diastolic pressure, which compared control values established for athletes. indexes determined serum subjects from means solid-phase ELISA method using conjugated antigens absorption plates. compare indexes, symptoms was examined. Diastolic cyclic combat below values, and, speed-strength sports, higher than group. A decrease above subgroup may indicate characteristic adaptive physiological myocardium. levels immune-related serotonin, dopamine all corresponded values. only exception concerned significantly differed normal category. Significantly high histamine angiotensin did not depend qualification. In involved bradykinin differ they exceeded norm. shown different types activities affect performance their own way. reflect regulatory state system. Accordingly, simultaneous increase against participation development diseases. differences sporting show deeper systems associated duration level physical activities.
