Novel monitoring method for the management of heart failure: combined measurement of body weight and bioimpedance index of body fat percentage

摘要

Although body weight scales are most commonly used to evaluate body fluid status during follow-up of definite heart failure (HF) patients, bioimpedance measurement methods have become increasingly available in the clinical setting. These monitoring methods, however, are typically used separately to evaluate body fluid status in HF patients. Kataoka developed a novel method for monitoring HF patients using a digital weight scale that incorporated a bioelectrical impedance analyzer. This method combines the well-known advantages of body weighing with a refined bioimpedance technique to monitor HF status and provides valid information regarding a change in a patient’s body fluid status during follow-up for HF, such as predominant fluid versus fat weight gain or loss. This special report describes examples of the practical use of this method for monitoring and treating definite HF patients.
