- W4386993502 abstract "Aim Hemodialysis (HD) patients have a high prevalence of frailty. The association between frailty and exercise capacity in HD patients has not been established. This study aimed to clarify the relationships between frailty and exercise capacity in HD patients. Methods This two‐center cross‐sectional study included HD patients who performed cardiopulmonary exercise testing. Participants were divided by frailty phenotype into robust, pre‐frail, and frail using the revised Japanese version of the Cardiovascular Health Study criteria. Peak oxygen uptake (peakVO 2 ) measured by cardiopulmonary exercise testing was compared with each frailty phenotype. The association between peakVO 2 and frailty phenotype was analyzed using multivariate linear regression analysis adjusted for age, sex, body mass index diabetes mellitus, cardiovascular disease, cancer, history of fracture, hemoglobin, left ventricle ejection fraction, and percentage of heart rate reserve. Results The study included 136 patients (median age, 71.0 years; female, 23.5%), with 15.4%, 44.9%, and 39.7% with frailty phenotypes robust, pre‐frail, and frail, respectively. PeakVO 2 decreased with deterioration of the frailty phenotype (robust, median 15.1 [13.7–18.3] mL/min/kg; pre‐frail, median 12.2 [10.5–14.4] mL/min/kg; frail, median 10.6 [9.2–12.5] mL/min/kg, P < 0.05). PeakVO 2 decline was significantly associated with frail ( B = −2.19, P = 0.004). Modeling individual frailty components showed a significant association between peakVO 2 , usual gait speed ( B = 2.38, P = 0.04), and low physical activity ( B = −1.44, P = 0.004). Conclusion Frailty in HD patients was associated with a decline in exercise capacity. HD patients with frailty need to improve exercise capacity, gait speed, and physical activity.
