Abstract
Background and Objectives: Extracellular water is increased in patients with edema, such as those with chronic heart failure, and it is difficult to assess skeletal muscle mass with the skeletal muscle mass index when extracellular water is high. We investigated the relationship between phase angle and physical function, nutritional indices, and sarcopenia in patients with cardiovascular diseases, including chronic heart failure. Methods and Study Design: In 590 patients with cardiovascular diseases (372 men), handgrip strength, gait speed, and anterior mid-thigh muscle thickness by ultrasound were measured, and the skeletal muscle mass index, phase angle, and the extracellular water: total body water ratio were measured with a bioelectrical impedance analyzer, and presence of sarcopenia was evaluated. Results: Phase angle, but not the skeletal muscle mass index, was correlated with serum albumin (r = 0.377, p < 0.001) and hemoglobin values in women. Multivariate regression analysis showed that at the extracellular water: total body water ratio below 0.4, both phase angle and skeletal muscle mass index were independent determinants of handgrip strength and log mid-thigh muscle thickness in men, after adjustment for age and presence of chronic heart failure. In contrast, for the ratio of 0.4 or greater, after adjustment for age and presence of chronic heart failure, phase angle was a stronger independent determinant of handgrip strength and log mid-thigh muscle thickness than the skeletal muscle mass index in men. Conclusions: Phase angle is a good marker of muscle wasting and malnutrition in patients with cardiovascular disease, including chronic heart failure.
期刊介绍:
The aims of the Asia Pacific Journal of Clinical Nutrition
(APJCN) are to publish high quality clinical nutrition relevant research findings which can build the capacity of
clinical nutritionists in the region and enhance the practice of human nutrition and related disciplines for health
promotion and disease prevention. APJCN will publish
original research reports, reviews, short communications
and case reports. News, book reviews and other items will
also be included. The acceptance criteria for all papers are
the quality and originality of the research and its significance to our readership. Except where otherwise stated,
manuscripts are peer-reviewed by at least two anonymous
reviewers and the Editor. The Editorial Board reserves the
right to refuse any material for publication and advises
that authors should retain copies of submitted manuscripts
and correspondence as material cannot be returned. Final
acceptance or rejection rests with the Editorial Board
