Eksperimentel: Frailty-specific prehabilitation program
A comprehensive prerehabilitation program which includes 4 components: 1) structured preoperative education; 2) nutritional optimization; 3) stress management; and 4) exercise training or usual care, respectively.
The prehabilitation will last for at least 4 weeks, continuing throughout the waiting period.
From Week 5 until the day of the surgery, the coach will offer support to encourage the participants to maintain self-practice by prescribing exercises that have previously been learned.

Sham-komparator: Attention placebo control
A sham stretching exercise intervention to neutralize the attention effects given by the intervener.
The exercise protocol consists of light-intensity stretching exercises.
The frequency and delivery format will be the same as the prehabilitation for the intervention group, but the duration is shortened to 30-minute per session.

|
Functional Capacity
Tidsramme: Baseline (T0), one-day before surgery (T1), postoperative 1 month (T2) and postoperative 3 months (T3)
|
Short Physical Performance Battery (SPPB) will be used to assess lower limb functional capacity.
It is well validated and has been widely adopted in clinical and research settings.
It consists of three timed-tasks: standing balance, walking speed, and chair-stand.
The timed results will be scaled to a score from 0 to 12, with higher scores indicating better functional capacity.
A hydraulic dynamometer (Jamar) will be used to evaluate grip strength of the dominant hand by maximal isometric contraction, taking the highest reading from at least two trials.

Tidsramme |
|---|---|---|
|
Frailty Status
Tidsramme: Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3).
|
The Edmonton Frail Scale (EFS) will be used to evaluate the level of frailty.
It consists of nine domains with performance-based and self-reported items scored from 0 to 17, with a higher score indicating a higher level of frailty.
|
Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3).

|
Cardiac-specific functional status
Tidsramme: Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3)
|
The Seattle Angina Questionnaire (SAQ-7) will be used to measure cardiac-related physical functioning.
It has seven items measuring three domains: physical limitation, angina frequency, and disease perception, scored on a 1-5 or 1-6 sequentially coded scale.
Subscale scores are transformed to a scale of 0-100, with higher scores indicating higher levels of functioning and fewer limitations.

|
Cardiac-specific HRQoL
Tidsramme: Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3)
|
The MacNew instrument will be used to measure cardiac-specific HRQoL.
It has 27 items scored on a scale of 1-7, and the global score is calculated by summing the item scores, with higher scores representing better HRQoL.
|
Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3)
|
|
Psychological distress
Tidsramme: Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3)
|
The Patient Health Questionnaire-4 will be used to measure psychological distress.
It consists of four items assessing anxiety and depression, with responses given on a 4-point Likert scale.
The composite total score ranges from 0 to 12, with higher scores indicating a greater level of anxiety and depression.

Biomarkers (serum albumin)
Tidsramme: Baseline (T0), 1 day before surgery (T1), 1 month after surgery (T2), and 3 months after surgery (T3)
|
Serum albumin (g/L) will be assayed according to standard laboratory guidelines in clinical settings
|

Major adverse cardiovascular and cerebral events (MACCEs) and hospital readmission rates
Tidsramme: From the time of enrollment in the study until 12 months after completing the intervention
|
MACCEs and hospital readmission rates will be monitored from the time of enrollment in the study until 12 months after completing the intervention through the review of the medical records.
MACCEs are defined as an acute myocardial infarction, stroke, heart failure, or any-cause mortality, using diagnosis codes from the International Classification of Diseases, Clinical Modification, tenth Revision.
