To assess the relationships between phase angle and muscle mass, strength, and physical function in patients with heart failure.
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.
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.
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.
评估心力衰竭患者的相位角与肌肉质量、力量及身体功能之间的关系。
本研究采用横断面设计。分析纳入了51例心力衰竭患者。测量了简短体能状况量表、单腿站立时间、握力、相位角和骨骼肌指数。为确定相位角的解释变量，进行了分层多元回归分析。
发现握力是相位角的一个解释变量，独立于年龄、性别和体重指数。该模型能够解释相位角模型方差的30.4%。
在心力衰竭患者中，改善肌肉力量而非肌肉质量或身体功能可能对改善相位角更为重要。握力是改善心力衰竭患者预后的一个重要指标。
