Patients were assigned to either the usual care group (April-May 2022) or the multidimensional digital CR intervention group (May-June 2022). The intervention group received rehabilitation through a nurse-led, multidisciplinary team, using a customized digital CR program. This program encompassed 7 key rehabilitation components: exercise, medication management, nutritional guidance, psychological support, sleep management, health education, and smoking cessation assistance. The usual care group received standardized treatment and routine nursing care. To minimize selection bias, propensity score matching was applied between the 2 groups. The primary outcomes included changes in the 6-minute walk test (6MWT), 12-item Short Form Health Survey (SF-12) scores, and frailty phenotype scores at 3 months. Secondary outcomes assessed differences in gait speed, 30-second chair stand test (30-s CST), grip strength, waist circumference (WC), BMI, and lipid profiles at 3 months.</jats:p>\n                  </jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results</jats:title>\n                    <jats:p>\n                      A total of 136 patients were included in the final analysis.
