Abstract

BACKGROUND: Deficit in the regulation of emotional stress is considered as an important factor in the development of coronary heart disease (CHD). The functions of assessment and regulation of emotions are performed by the structures of the prefrontal cortex and amygdala, the activation and interaction of which differs in men and women. In this regard, the question of the gender specificity of the cortical mechanisms of emotional regulation associated with coronary artery disease is relevant. AIMS: to find out the significance of self-assessment of emotional control of behavior (EC) in the frequency-spatial organization of brain activity in men and women with CHD. METHODS: To analyze the frequency-spatial organization of the resting EEG, we used 64-channel EEG recording and calculation of the power of rhythms in six frequency ranges from 4 to 30 Hz using a fast Fourier transform. Spearman's non-parametric correlation analysis was used to determine the correlation of EC as a personality trait according to the questionnaire of emotional intelligence and EEG power indicators. RESULTS: The study was performed in a cardiology clinic involving 56 men (61.2 8.5 years) and 19 women (67.4 4.8 years) diagnosed with CAD. Correlation analysis of EC and average EEG power indicators revealed positive relationships in the range of 4-13 Hz in the group of men and negative in the group of women (0.19Rs0.28 and -0.20Rs-0.40, respectively; p0.030). The regional specificity of the detected effect was characterized by a significant relationship between EC and the power of theta2, alpha1, 2, presented in the anterior part of the cortex with the dominance of the left hemisphere in men, but in the posterior part of both hemispheres - in women, and the latter effect was limited by theta 2 and alpha 1 frequency. CONCLUSIONS: The results of the performed analysis of the relationship of EC and regional indicators of resting EEG power in the 6-13 Hz range indicate different forms of control of the emotional state in women and men with CHD.

冠心病患者大脑活动频率-空间组织的特异性与男性和女性情绪控制自我评估相关

背景:情绪应激调节不足被认为是冠心病(CHD)发生的重要因素。评估和调节情绪的功能是由前额叶皮层和杏仁核的结构完成的，其激活和相互作用在男性和女性中是不同的。在这方面，与冠状动脉疾病相关的情绪调节皮质机制的性别特异性问题是相关的。目的:探讨行为情绪控制自评(EC)在男女冠心病患者脑活动频率空间组织中的意义。方法:为了分析静息脑电图的频率-空间组织，我们使用64通道脑电图记录并使用快速傅立叶变换计算4 ~ 30 Hz 6个频率范围内的节奏功率。根据情绪智力问卷和脑电图功率指标，采用Spearman非参数相关分析确定人格特质与情商的相关性。结果:该研究在一家心脏病学诊所进行，涉及56名男性(61.2 - 8.5岁)和19名女性(67.4 - 4.8岁)诊断为CAD。电导率与平均脑电功率指标的相关分析显示，男性组在4 ~ 13 Hz范围内呈正相关，女性组为负相关(分别为0.19 rs ~ 0.28和-0.20 rs ~ 0.40);p0.030)。检测到的效果的区域特异性表现为EC与θ 2， α 1， α 2的功率之间存在显著的关系，在男性中，θ 2， α 1， α 2的功率主要出现在左半球的皮质前部，而在女性中，θ 2， α 1的功率主要出现在两个半球的后部，后者的效果受到θ 2和α 1频率的限制。结论:对6 ~ 13 Hz静息脑电功率区域指标与EC的关系进行分析，提示男女冠心病患者的情绪状态控制形式不同。

期刊介绍： “Genes and Cells” (the old name is “Cell Transplantology and Tissue Engineering”) is a peer-reviewed scientific and practical journal recommended by the Higher Attestation Commission of the Ministry of Education and Science of the Russian Federation for publishing basic materials of dissertation research. Originally conceived as a highly specialized publication, the Journal has now gained an ever wider target audience. If at the beginning of its journey — from September 2005 — the target audience of the journal were biotechnologists, specialists in the field of molecular and cell biology, by now it has expanded with medical practitioners. Such progressive dynamics are absolutely natural — over the last 7-10 years, biomedical technologies have come out of the exotic category, lack of understanding of the inhabitants and mistrust of clinicians have been replaced by interest and awareness of the need to use biotechnology tools in medicine no longer tomorrow, but today. The sections of the journal are formulated to fully disclose the target topics of the publication, convey to readers the opinions of leading experts in the field of biomedical technologies on topical issues of concern, acquaint them with the most significant recent foreign and domestic research, materials of thematic conferences, present analytical information on fundamental issues of biomedical technologies trends in the biotech business. The journal includes the following headings: “expert opinions”, “cell technology news”, “reviews”, “original research”, “clinical experience”, “discussion and general theoretical work”, “stem cell business”.
