The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is a well-validated, commonly-used tool to assess quality of life in patients with heart failure. However, it lacks specific information concerning breathlessness during daily activities.
To determine the validity of the London Chest Activity of Daily Living (LCADL) scale for use in patients with heart failure.
Forty-seven patients with heart failure (57% males, mean age 50 years (standard deviation 9), mean left ventricle ejection fraction 29% (SD 6), New York Heart Association (NYHA) functional class I-III) were included. All subjects first performed a cardiopulmonary exercise test and then responded to the LCADL and the MLHFQ, with guidance from the same investigator. The re-test for the LCADL was applied one week later.
LCADL was correlated with MLHFQ (r = 0.88; p < 0.0001). LCADL and MLHFQ were also correlated with exercise capacity (r = -0.75 and r = -0.73, respectively; both p < 0.0001). The LCADL was shown to be reproducible (ri = 0.98). There was a significant difference (p < 0.05) in the LCADL scores between NYHA functional classes I and II, as well as classes I and III, but not between classes II and III.
The LCADL was shown to be a valid measurement of dyspnoea during daily activities in patients with heart failure. This scale could be an additional useful tool for the assessment of patients' dyspnoea during activities of daily living.
明尼苏达心力衰竭生活质量问卷（MLHFQ）是一种经过充分验证、常用于评估心力衰竭患者生活质量的工具，但它缺乏有关日常活动时呼吸困难的具体信息。
确定伦敦日常活动呼吸困难量表（LCADL）在心力衰竭患者中的有效性。
纳入 47 例心力衰竭患者（57%为男性，平均年龄 50 岁（标准差 9），平均左心室射血分数 29%（标准差 6），纽约心脏协会（NYHA）心功能 I-III 级）。所有患者首先进行心肺运动试验，然后由同一位研究者指导他们回答 LCADL 和 MLHFQ。一周后对 LCADL 进行复测。
LCADL 与 MLHFQ 呈高度相关（r = 0.88；p < 0.0001）。LCADL 和 MLHFQ 也与运动能力相关（r = -0.75 和 r = -0.73，均 p < 0.0001）。LCADL 具有良好的可重复性（ri = 0.98）。NYHA 心功能 I 级和 II 级、I 级和 III 级之间的 LCADL 评分存在显著差异（p < 0.05），但 II 级和 III 级之间无显著差异。
LCADL 是评估心力衰竭患者日常活动时呼吸困难的有效工具。该量表可能是评估患者日常活动时呼吸困难的另一个有用工具。
