Fatigue after myocardial infarction (MI) has been found to be distressing. A person's self-efficacy will influence his/her health behavior and plays an active role in tackling illness consequences. This study investigated associations between fatigue, disturbed sleep, general self-efficacy, and health-related quality of life (HRQoL) in a sample of 145 respondents admitted to hospital for MI two years earlier. The aim was to identify the predictive value of general self-efficacy and to elucidate mediating factors between self-efficacy and HRQoL. General self-efficacy measured four months after MI was positively related to HRQoL after two years. In tests of indirect effects, fatigue meditated the effects between self-efficacy and the physical and the mental dimension of HRQoL, respectively. The indirect effect of disturbed sleep went through that of fatigue. To conclude, patients who suffer from post-MI fatigue may need support aimed at helping them increase their self-efficacy as well as helping them adapt to sleep hygiene principles and cope with fatigue, both of which will have positive influences on HRQoL.
心肌梗死后的疲劳一直被认为是令人痛苦的。一个人的自我效能感会影响他/她的健康行为，并在应对疾病后果方面发挥积极作用。本研究调查了 145 名两年前因心肌梗死住院的患者的疲劳、睡眠障碍、一般自我效能感与健康相关生活质量（HRQoL）之间的关联。目的是确定一般自我效能感的预测价值，并阐明自我效能感与 HRQoL 之间的中介因素。心肌梗死后四个月测量的一般自我效能感与两年后 HRQoL 呈正相关。在间接效应检验中，疲劳分别介导了自我效能感与 HRQoL 的身体和心理维度之间的关系。睡眠障碍的间接效应通过疲劳起作用。总之，患有心肌梗死后疲劳的患者可能需要支持，旨在帮助他们提高自我效能感，帮助他们适应睡眠卫生原则，并应对疲劳，这两者都会对 HRQoL 产生积极影响。
