| Patient-reported health-related quality of life assessed by using the European Quality of Life 5 Dimension 5 Level (EQ-5D-5L) questionnaire | Baseline | EQ-5D-5L consists of five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each with five levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The total score ranges from -0.025 to 1, and higher scores reflect better health status. |
| Patient-reported health-related quality of life assessed by using the Hospital Anxiety Depression Scale (HADS) | Baseline | HADS is an anxiety and depression assessment scale consisting of seven items (rated 0, 1, 2, or 3) related to anxiety (subscale A) and seven other items related to depression (subscale D). The total score ranges from 0 to 14, and higher scores reflect a worse health status. |
| Patient-reported health-related quality of life assessed by using the Kansas City Cardiomyopathy Questionnaire (KCCQ) | Baseline | The KCCQ is a 23-item questionnaire developed to assess HRQoL in patients with congestive heart failure. The KCCQ consists of five domains: physical limitation, symptoms (frequency, severity, and recent change over time), QoL, social interference, and self-efficacy. The total score ranges from 0 to 100, and higher scores reflect better health status. |
