Brief Summary:

Exercise training in patients with coronary artery disease is able to correct several risk factors. Furthermore endothelial function can be improved.

There are some hinds for improved collateral circulation after exercise training, nevertheless there is no study showing significant improvement/ increase in coronary collaterals. This might be due to technique of collateral measurement. Therefore we conduct a study were coronary blod flow before and after 4 weeks of exercise training were measured.

Arm Intervention/treatment
No Intervention: control
standard care of coronary artery diseases incl. recommended home based exercise 3x/week
Active Comparator: Exercise training
exercise training for 4 weeks at 70% of ischemia free individual threshold within a rehabilitation care center
Behavioral: exercise training
exercise training min. 4 times a day for at least 30 min

Active Comparator: intensive exercise training
intensive exercise training incl. interval training
Behavioral: Intensive exercise training
Intensive exercise training for 4 times / day incl. interval training at 95% individual threshold

Primary Outcome Measures :
  1. coronary collateral blod flow [ Time Frame: 4 weeks ]

Secondary Outcome Measures :
  1. plaque composition within the coronary artery [ Time Frame: 4 weeks ]
    plaque composition measured by virtual histology intravascular ultrasound

  2. MACCE [ Time Frame: 4 week, 6 months, 12 months ]
    major cardiovascular events (death, myocardial infarction, stroke, TIA, coronary revascularisation, hospitalisation)

  3. atherosclerosis parameter within the laboratory [ Time Frame: 4 weeks, 3, 6, 12 months ]
    e.g. wie hs-CRP, HDL, LDL, ges. Cholesterin, Triglyceride, Zytokine, Adipokine, Endocannaboide
