The common heart failure (HF) symptoms-dyspnea, fatigue, and edema-often prompt emergency visits. Dyspnea notably affects activities of daily living (ADLs), making its assessment crucial for evaluating therapeutic success. This study assesses the reliability and validity of the European Portuguese version of the London Chest Activity of Daily Living (LCADL) scale, originally validated in 2010, to evaluate ADL limitations in patients with HF. Following international guidelines for translation and cultural adaptation, 46 patients with HF from two cardiology departments were enrolled. The Six Minute Walk Test (6MWT) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were used for construct validity. A significant correlation was found between the results of the 6MWT and the LCADL total score (r = -0.504; < 0.001) and the LCADL scale and the MLHFQ (r = 0.703; < 0.001), except for the domestic activities dimension (r = 0.278; = 0.062). Reliability revealed an α of 0.917. The study presents the validation of the European Portuguese version of the LCADL scale in patients with HF, emphasizing its reliability and cultural appropriateness. The LCADL scale has proven effective in assessing dyspnea-induced limitations in ADLs, and this study expands its utility by suggesting broader clinical setting applications. Future research should explore its adaptability in diverse healthcare settings, potentially enhancing personalized care strategies and patient outcomes. This work underscores the LCADL scale's role in facilitating more targeted and effective interventions for managing ADL limitations in patients with HF, suggesting a significant impact on clinical practices and patient care management.
常见的心力衰竭（HF）症状——呼吸困难、疲劳和水肿——常常促使患者前往急诊。呼吸困难对日常生活活动（ADL）有显著影响，因此对其进行评估对于评估治疗效果至关重要。本研究评估了2010年最初验证的《伦敦胸部日常生活活动（LCADL）量表》欧洲葡萄牙语版本的信度和效度，以评估HF患者的ADL受限情况。按照国际翻译和文化调适指南，招募了来自两个心脏病科的46名HF患者。使用六分钟步行试验（6MWT）和明尼苏达心力衰竭生活问卷（MLHFQ）进行结构效度评估。发现6MWT结果与LCADL总分（r = -0.504；<0.001）以及LCADL量表与MLHFQ之间存在显著相关性（r = 0.703；<0.001），家务活动维度除外（r = 0.278；= 0.062）。信度显示α为0.917。该研究展示了LCADL量表欧洲葡萄牙语版本在HF患者中的验证情况，强调了其信度和文化适宜性。LCADL量表已被证明在评估呼吸困难引起的ADL受限方面有效，本研究通过建议更广泛的临床应用场景扩展了其效用。未来的研究应探索其在不同医疗环境中的适应性，可能会增强个性化护理策略和患者预后。这项工作强调了LCADL量表在促进针对HF患者ADL受限进行更有针对性和有效干预方面的作用，表明对临床实践和患者护理管理有重大影响。
