Segmental phase angles can moderately predict frailty in older hospitalized men with cardiovascular disease, highlighting potential clinical utility.
Frailty was present in 28.66% of the 157 hospitalized patients, indicating a significant health concern in this population.
Lower phase angles were associated with frailty, alongside relevant biomarkers such as low hemoglobin and elevated CRP levels.
Further studies are needed to refine the usefulness of segmental phase angle cutoffs, particularly for women.
