Abstract

Objective: To assess the relationships between phase angle and muscle mass, strength, and physical function in patients with heart failure.

Methods: This study used a cross-sectional design. The analysis included 51 patients with heart failure. The Short Physical Performance Battery, one-leg standing time, handgrip strength, phase angle, and skeletal muscle index were measured. To identify explanatory variables of phase angle, hierarchical multiple regression analysis was performed.

Results: Handgrip strength was found to be an explanatory variable of phase angle independent of age, sex, and body mass index. This model was able to explain 30.4% of the model variance for phase angle.

Conclusion: In patients with heart failure, improving muscle strength rather than muscle mass or physical function might be more important for improving phase angle. Handgrip strength is an important outcome for improving prognosis in patients with heart failure.

相位角与老年心力衰竭患者握力的关系

目的:探讨心力衰竭患者的相位角与肌肉质量、力量和身体功能的关系。方法:本研究采用横断面设计。该分析包括51例心力衰竭患者。测量短时体能测试、单腿站立时间、握力、相位角和骨骼肌指数。为了确定相位角的解释变量，进行了层次多元回归分析。结果:握力是相位角的解释变量，与年龄、性别、体质指数无关。该模型能够解释相位角模型方差的30.4%。结论:对于心力衰竭患者，改善相位角可能更重要的是改善肌力而不是肌肉质量或身体功能。握力是改善心衰患者预后的重要指标。
