Study Description

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.

Arms and Interventions

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

Outcome Measures

Primary Outcome Measures

  1. coronary collateral blod flow [4 weeks]

Secondary Outcome Measures

  1. plaque composition within the coronary artery [4 weeks]

    plaque composition measured by virtual histology intravascular ultrasound

  2. MACCE [4 week, 6 months, 12 months]

    major cardiovascular events (death, myocardial infarction, stroke, TIA, coronary revascularisation, hospitalisation)

  3. atherosclerosis parameter within the laboratory [4 weeks, 3, 6, 12 months]

    e.g. wie hs-CRP, HDL, LDL, ges. Cholesterin, Triglyceride, Zytokine, Adipokine, Endocannaboide
