Title: Rehabilitation After Coronary Bypass Grafting: Home Based Rehabilitation Versus Rehabilitation in Institution and Rehabilitation in Institution Versus Out-patient Rehabilitation at the Hospital
Brief Summary: The purpose of this study is to compare different types of rehabilitation after coronary bypass surgery. The investigators wish to compare rehabilitation in an institution for four weeks with a home based rehabilitation. They also wish to compare rehabilitation in an institution for four weeks with a rehabilitation program were the patients live at home but visit the hospital twice a week for twelve week. The investigators will measure the patients' physical capacity by measuring their maximal oxygen consumption. The investigators will also analyze their blood and their endothelian function (how well their arteries dilate).


Options:

C: Inclusion Criteria:

* Patients aged 60 years and older, undergoing elective isolated coronary artery bypass grafting (CABG), aortic valve repair/replacement for moderate aortic stenosis or severe regurgitation, mitral valve repair/replacement for moderate stenosis or severe regurgitation or combined CABG/valve procedures
* Patients with Clinical Frailty Score (CFS) ≥3 (vulnerable) and \< 7 (8 = very severely frail, approaching end-of-life or 9 = terminally ill) at time of acceptance for cardiac surgery
* Patients with an estimated ≥ 6 week wait time

Exclusion Criteria:

* Patients who have unstable or recent unstable cardiac syndrome as defined by:

  1. Severe heart failure (NYHA IV) or angina (CCS class IV) symptoms
  2. Critical left main (LM) coronary disease
  3. Hospitalization for arrhythmias, congestive heart failure or acute coronary syndrome prior to randomization
* Patients who have severe left ventricular obstructive disease as defined by:

  1. Severe aortic or mitral stenosis (aortic or mitral valve area \<1.0cm2 or mean gradient \> 40 mmHg or \> 10 mmHg respectively)
  2. Dynamic left ventricular (LV) outflow obstruction
* Patients who have demonstrated exercise induced ventricular arrhythmias or have experienced a recent hospitalization for arrhythmias
* Patients who have cognitive deficits that would preclude rehabilitation

* Ability to read and speak English to a level allowing satisfactory completion of written questionnaires and to understand instruction during the exercise programme.

Exclusion Criteria:

* Acute coronary syndromes or recent myocardial infarction (\<2 months)
* Left main coronary artery stenosis \>25% or high-grade proximal left anterior descending artery stenosis
* Known reduced left ventricular function (ejection fraction \<40%)
* Significant valvular heart disease
* Insulin-dependent diabetes mellitus
* Occupational, orthopedic, and other conditions that preclude regular exercise
* Patients whose ECG prevents interpretation of an exercise test (LBBB, RBBB, pacemaker implantation).
* Patients who already perform greater than 30min continuous exercise three times weekly (self-reported).
