Inclusion criteria

Inclusion criteria: Patients hospitalized for heart failure or patients with an implanted left ventricular assist device(LVAD)at our hospital Age >= 20 years Patients who have received an explanation of the study objectives and methods and have provided written informed consent

Exclusion criteria

Exclusion criteria: Patients with skin lesions on the forehead that make sensor attachment difficult Patients with severe activity limitation who cannot undergo exercise testing or rehabilitation Patients judged inappropriate for participation by the principal investigator

Design outcomes

Primary

MeasureTime frame
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).

Secondary

MeasureTime frame
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).
