The purpose of this study was to explore adult women's unique and shared experiences of prodromal myocardial infarction fatigue.
Fatigue is the most prevalent symptom experienced by women in the weeks and months before myocardial infarction. However, dimensions of this fatigue, such as timing, distress, intensity, quality, patterns and associated characteristics have not been established through studies of this symptom. A lack of understanding of the characteristics of myocardial infarction fatigue and the context in which it occurs makes clinical decision-making difficult.
A qualitative, multiple case study guided by the Theory of Unpleasant Symptoms.
Women were purposively enrolled from a large hospital in the Midwestern USA. Semi-structured, audio-recorded interviews were conducted during hospitalisation and at 2-3 months postdischarge; women were also provided with a journal. A supplementary interview with family members and electronic health record review also assisted in data triangulation. Analysis was inductive and conducted within and across cases, using coding and categorisation, counting, clustering, visual displays of data and thematic development. The SRQR checklist was used in reporting the study.
Ten women, with a median age of 60, participated. Fatigue was described primarily using the terms tiredness and lack of energy, though some women described generalised weakness and cognitive fog. This fatigue was unusual and a notable change from baseline. Many women described significant difficulties performing activities of daily living due to fatigue.
The findings of this study will advance symptom science and an understanding of prodromal myocardial infarction fatigue. Future instrument development or selection of instruments for quantitative work will be aided by this study.
This study provides a clearer picture of prodromal myocardial infarction fatigue experienced by women, aiding healthcare professionals in understanding and identifying this symptom.
本研究旨在探讨成年女性在心肌梗死前驱期疲劳方面的独特和共同体验。
疲劳是女性在心肌梗死前数周和数月内最常经历的症状。然而，通过对该症状的研究，尚未确定这种疲劳的维度，如出现时间、痛苦程度、强度、质量、模式和相关特征。对心肌梗死疲劳的特征以及发生这种疲劳的背景缺乏了解，使得临床决策变得困难。
一项由理论指导的定性、多案例研究。
本研究从美国中西部一家大医院有目的地招募了女性。在住院期间和出院后 2-3 个月进行了半结构化、录音采访；还为女性提供了日记。对家庭成员进行补充访谈和电子病历回顾也有助于数据三角验证。分析是在案例内和案例间进行的，使用编码和分类、计数、聚类、数据的可视化显示和主题发展。使用 SRQR 清单报告研究。
10 名女性参与了研究，中位年龄为 60 岁。疲劳主要使用疲倦和缺乏能量来描述，尽管一些女性描述了全身无力和认知障碍。这种疲劳是不寻常的，与基线相比有明显的变化。许多女性因疲劳而难以完成日常生活活动。
本研究的结果将推进症状科学和对前驱期心肌梗死疲劳的理解。未来的仪器开发或定量工作中仪器的选择将得益于本研究。
本研究更清楚地描述了女性经历的前驱期心肌梗死疲劳，帮助医疗保健专业人员理解和识别这种症状。
