“…Причини виникнення ЦД 1 типу, який складає 10-15 % всіх випадків ЦД, вивчені недостатньо, тому запобігти захворюванню майже неможливо. Водночас з'ясовано, що виникнення ЦД 2 типу пов'язане переважно з надлишком ваги та браком фізичної активності і йому можна запобігти у 80 % випадків [2].

ST-segment elevation myocardial infarction, stenting of the infarct-related coronary artery, silent (painless) myocardial ischemia, diabetes mellitus, 24-hour electrocardiographic monitoring. Introduction. Currently, approximately 422 million people in the world have diabetes mellitus, and over 1.3 million individuals in Ukraine are diagnosed with diabetes mellitus. Diabetic neuropathy is known to contribute to the development of atypical and painless variants of ischemic heart disease in individuals with diabetes. This poses a challenge for timely diagnosis and obscures the course of ischemic heart disease, as the prevalence of silent myocardial ischemia is significantly high in these patients. Therefore, the aim of this study is to investigate the occurrence of myocardial ischemia episodes in patients with ST-elevation myocardial infarction within the first day following stenting of the infarct-related coronary artery. Furthermore, we aimed to demonstrate the painless nature of these episodes in the presence of type 2 diabetes mellitus through a clinical case presentation. Materials and methods. 30 patients with ST-segment elevation myocardial infarction were examined, and 24-hour electrocardiographic monitoring was performed during the first day after the infarct-related coronary artery stenting. Results. Episodes of transient myocardial ischemia were registered in 50% of people. We found that the majority of episodes (80%) were painless. In the presence of diabetes mellitus, only episodes of painless myocardial ischemia were noted that is supported by the example of a clinical case. The study highlighted the informativeness of 24-hour electrocardiographic monitoring in identifying episodes of myocardial ischemia, particularly in its painless variant. The results demonstrate that patients with ST-elevation myocardial infarction (STEMI) experience episodes of transient myocardial ischemia within the first day after coronary artery stenting, with a majority of these episodes being painless. Furthermore, in the presence of diabetes mellitus, ischemic episodes tend to be painless. Therefore, 24-hour electrocardiographic monitoring serves as a valuable method for the detection of myocardial ischemia.

To date, the issues of evaluating the course of silent myocardial ischemia (SMI) after a myocardial infarction (MI) taking into account risk factors (RF), evaluating the pathological turbulence of the heart rhythm, the state of activation of the body’s antinociceptive system, which necessitates an in-depth study of this pathology, remain unresolved, as well as new differentiated approaches to the treatment and rehabilitation of the modern category of patients. The objective: to analyze the features of the SMI course in patients with post-infarction cardiosclerosis depending on the RF. Identification of the interdependence between the degree of activation of the sympathoadrenal system and the features of the SMI course in patients with post-infarction cardiosclerosis, as well as the prognostic value for assessing the severity of the course of the disease. Materials and methods. The research was performed on the basis of the Ivano-Frankivsk Regional Clinical Cardiology Center (Ukraine). 154 patients with a silent form of coronary artery disease, which occurred in people with post-infarction cardiosclerosis, were examined. The diagnostic criteria were: episodes of SMI verified with the help of HM ECG and a test with dosed physical load. Results. Significant deviation of the ST segment which was detected during Holter monitoring of the ECG (HM ECG) in patients with SMI episodes does not mean that the absence of pain sensations in the presence of efferent nociceptive stimulation is a sign of the absence of ischemia and does not indicate an easier course of SMI compared to clinically manifest forms of CHD. The average concentration of β-endorphins in patients with lipid metabolism disorders was 4.01±0.02 ng/ml, in the presence of diabetes mellitus this indicator was equal to 4.68±0.03 ng/ml (р<0.01), and in persons with concomitant arterial hypertension it was 4.91±0.02 ng/ml (р<0.05). In subjects with two or more RFs, the similar indicator was the highest and amounted to 5.73±0.03 ng/ml (р<0.01). The point-biserial correlation coefficient was equal to 0.61 (р<0.05), which indicates a sufficiently high probability of the influence of the processes of activation of the antinociceptive system on the risk of myocardial infarction and unstable angina. Conclusions. It has been proven that the presence of postinfarction cardiosclerosis, type 2 diabetes mellitus, dyslipidemia, and arterial hypertension should be considered as factors that increase the risk of complications of coronary artery disease in patients with SMI. In the painless form of CHD, there is a probable increase in β-endorphins in the blood, which indicates the presence of pronounced afferent nociceptive stimulation, the intensity of which depends on the degree of myocardial ischemia. It has been proven that an increase of β-endorphins levels is associated with an increase in the risk of a complicated course of coronary heart disease in patients with silent myocardial ischemia. The presence in patients with SMI of myocardial ischemia, pathological turbulence of the heart rhythm, and activation of the antinociceptive system are extremely important for understanding the main links of the course of SMI and make it possible to base the approach to the therapy of such patients on a differentiated system algorithm that takes into account the discrepancy between the clinical manifestations of the disease and its real impact on coronary perfusion and the condition of the vascular wall.

Introduction: Arterial hypertension (AH) is a pervasive global health concern with multifaceted origins encompassing both genetic and environmental components. Previous research has firmly established the association between AH and diverse genetic factors. Consequently, scientists have conducted extensive genetic investigations in recent years to unravel the intricate pathophysiology of AH.Methods: In this study, we conducted a comprehensive bibliometric analysis employing VOSviewer software to identify the most noteworthy genetic factors that have been the focal point of numerous investigations within the AH field in recent years. Our analysis revealed genes and microRNAs intricately linked to AH, underscoring their pivotal roles in this condition. Additionally, we performed molecular docking analyses to ascertain microRNAs with the highest binding affinity to these identified genes. Furthermore, we constructed a network to elucidate the in-silico-based functional interactions between the identified microRNAs and genes, shedding light on their potential roles in AH pathogenesis.Results: Notably, this pioneering in silico examination of genetic factors associated with AH promises novel insights into our understanding of this complex condition. Our findings prominently highlight miR-7110-5p, miR-7110-3p, miR-663, miR-328-3p, and miR-140-5p as microRNAs exhibiting a remarkable affinity for target genes. These microRNAs hold promise as valuable diagnostic and therapeutic factors, offering new avenues for the diagnosis and treatment of AH in the foreseeable future.Conclusion: In summary, this research underscores the critical importance of genetic factors in AH and, through in silico analyses, identifies specific microRNAs with significant potential for further investigation and clinical applications in AH management.
