Title: Effect of High Intensity Aerobic Interval Training in Cardiac Rehabilitation
Brief Summary: The purpose of the study is to compare home-based aerobic interval training with supervised interval training performed in groups or on a treadmill at the hospital.


Options:
A: Inclusion Criteria:

* coronary artery disease
* age over 18
* referred to cardiac rehabilitation
* exercise tolerance demonstrated

Exclusion Criteria:

* severe arrhythmia
* heart failure
* drug abuse
* pregnancy
B: Inclusion Criteria:

* Patients with an acute coronary syndrome treated with primary or elective PCI or coronary surgery (CABG), with a stable medical condition and providing written informed consent are eligible to participate.
* Men and women who signed informed consent.
* Patients are eligible to participate in the study if they are: able to regularly attend a supervised exercise programme and able to complete Dutch language questionnaires.

Exclusion Criteria:

* Patients with heart failure
* Impaired left ventricular function (LVEF\<40%)
* Psychic or cognitive impairments
* Severe arrhythmias
* Heart valve disease
* Congenital disease
* Severe co-morbidities which limit the CR (e.g. severe COPD, severe diabetes or locomotive disorder) and patients with an ICD will be excluded.
C: Inclusion Criteria:

* Diagnosis of Coronary Heart Disease (CHD)
* Eligibility for Cardiac Rehabilitation (CR) in North Carolina
* Capacity to give informed consent and follow study procedures

Exclusion Criteria:

Exclusion Criteria:

* significant illness during the last 6 weeks
* known severe ventricular arrhythmia with functional or prognostic significance
* significant myocardial ischemia, hemodynamic deterioration or exercise-induced arrhythmia at baseline testing
* cardiac disease that limits exercise tolerance (valve disease with significant hemodynamic consequences, hypertrophic cardiomyopathy etc.)
* co-morbidity that may significantly influence one-year prognosis
* functional or mental disability that may limit exercise
* acute or chronic inflammatory diseases or malignancy, the use of anti-inflammatory drugs or immune suppression
* GFR \<25ml/min/1.73m2
