Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is presenteeism, which will be assessed using the Japanese version of the Work Limitations Questionnaire. The assessment will be conducted at baseline and at 12 weeks to evaluate changes over time. | — |
Secondary
| Measure | Time frame |
|---|---|
| Health-related quality of life will be assessed using the EQ-5D-5L. Exercise tolerance will be evaluated based on peak oxygen uptake and anaerobic threshold obtained from cardiopulmonary exercise testing. Physical function will be assessed through isometric knee extension strength using a muscle strength measurement device, and by evaluating balance, gait speed, and the five-time sit-to-stand test using the Short Physical Performance Battery (SPPB). Adherence will be assessed by the number of outpatient visits and the number of web-based guidance sessions during the study period. Cardiac disease control will be evaluated by measuring NT-proBNP levels in blood samples. | — |
