The aim of this study is to evaluate the validity and feasibility of sweat lactate threshold (sLT) measurement using a sweat lactate sensor in patients with heart failure and implanted left ventricular assist devices, in order to explore its utility as a non-invasive method for assessing exercise capacity.
Safety,Efficacy
Agreement between sweat lactate threshold (sLT) and ventilatory threshold (VT) in patients who underwent cardiopulmonary exercise testing (CPX), assessed by correlation coefficient and Bland-Altman analysis. The evaluation will be performed at baseline (registration).
Success rate of sweat lactate threshold (sLT) measurement in all subjects, determined by three independent evaluators. Evaluation at baseline (registration).
Association of sLT with exercise heart rate, Borg scale, and walking distance. Evaluation at baseline (registration).

This study will be conducted as an exploratory clinical study with the approval of the Ethics Committee of Tokyo Science University Hospital. The sweat lactate sensor (GI-1) used in this study is provided free of charge by Grace Imaging Inc., and the investigators have no financial conflicts of interest. Patient enrollment will begin after ethics committee approval.
