Given that approximately one-third of individuals with coronary artery disease (CAD) remain severely fatigued after completion the cardiac rehabilitation, it is necessary to identify reliable intervention targets aimed at reducing fatigue. Perceived social support is closely linked to health outcomes and depressive symptoms in individuals with CAD. However, to our knowledge, the relationship between subjective fatigue levels and social support in those with CAD has not been analyzed. We aimed to examine the associations between perceived social support and subjective fatigue levels in individuals with CAD with and without depression symptoms. This cross-sectional study was comprised of 1,036 participants with CAD (57±9years, 77% men) 1-2weeks after acute coronary syndrome (ACS). Participants completed the Hospital Anxiety and Depression scale (HADS), Multidimensional Fatigue Inventory-20 (MFI-20), and the Multidimensional Scale of Perceived Social Support (MSPSS). In total, 12% (=129) of study participants had elevated depression symptoms (HADS score≥8). In individuals with CAD and depressive symptoms, after adjustment for sex, age, New York Heart Association (NYHA) functional class, and anxiety, linear regression analyses showed significant inverse associations between higher social support from others and general, physical fatigue as well as reduced activity and motivation (<0.001). Following the same method of statistical analysis and control in non-depressed individuals with CAD (88%), social support from family was inversely linked to mental fatigue ('s<0.05). Similarly, social support from friends was significantly associated with lower general, physical, and mental fatigue as well as reduced activity, while social support from others was significantly associated with lower general and mental fatigue ('s<0.001). The overall higher total support was linked with reduced motivation (<0.05) in the depressed study participants, while there was lower general and mental fatigue (<0.05) in non-depressed individuals. The results of this study suggest that fatigue and its features could be associated by the perceived social support in individuals with CAD following ACSs. While in individuals with CAD and depressive symptoms, greater subjective fatigue is associated with less perceived social support from others, higher levels of subjective fatigue in non-depressed individuals with CAD are significantly associated with reduced perceived social support from friends.
鉴于约三分之一的冠心病（CAD）患者在完成心脏康复后仍严重疲劳，有必要确定旨在减轻疲劳的可靠干预目标。感知到的社会支持与CAD患者的健康状况和抑郁症状密切相关。然而，据我们所知，CAD患者主观疲劳水平与社会支持之间的关系尚未得到分析。我们旨在研究有和没有抑郁症状的CAD患者中，感知到的社会支持与主观疲劳水平之间的关联。这项横断面研究由1036名急性冠状动脉综合征（ACS）后1 - 2周的CAD患者组成（年龄57±9岁，男性占77%）。参与者完成了医院焦虑抑郁量表（HADS）、多维疲劳量表-20（MFI - 20）和感知社会支持多维量表（MSPSS）。总共有12%（=129）的研究参与者有抑郁症状加重（HADS评分≥8）。在有CAD和抑郁症状的个体中，在对性别、年龄、纽约心脏协会（NYHA）功能分级和焦虑进行调整后，线性回归分析显示来自他人的更高社会支持与总体、身体疲劳以及活动和动力降低之间存在显著的负相关（<0.001）。在无抑郁症状的CAD患者（88%）中采用相同的统计分析和控制方法，来自家人的社会支持与精神疲劳呈负相关（P<0.05）。同样，来自朋友的社会支持与较低的总体、身体和精神疲劳以及活动减少显著相关，而来自他人的社会支持与较低的总体和精神疲劳显著相关（P<0.001）。在有抑郁症状的研究参与者中，总体社会支持较高与动力降低相关（P<0.05），而在无抑郁症状的个体中，总体和精神疲劳较低（P<0.05）。这项研究的结果表明，ACS后CAD患者的疲劳及其特征可能与感知到的社会支持有关。在有CAD和抑郁症状的个体中，更大的主观疲劳与来自他人的较少感知社会支持相关，而在无抑郁症状的CAD患者中，较高水平的主观疲劳与来自朋友的较少感知社会支持显著相关。
