Brief Summary

Introduction: Regular exercise training improves prognosis in patients with coronary artery disease (CAD). This study investigates whether the beneficial effects of exercise can be partly explained by favourable changes in haemostasis and inflammation. Methods: 150 CAD patients are randomised to a supervised long-term exercise program (3 months) or usual care. Blood samples are obtained at baseline, 1.5 months, and 3 months after randomisation. Results: The investigators will evaluate platelet turnover and aggregation, coagulation, fibrinolysis, and inflammatory markers before and after short- and long-term exercise, and the two randomised groups will be compared. Perspectives: The present study will increase our knowledge of the beneficial mechanisms underlying the effect of exercise in CAD patients, potentially paving the way for improved exercise recommendations.

Outcome Measures

Primary Outcomes (4)

  • Changes in fibrinolytic biomarkers: tissue plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1).

    Changes in fibrinolytic biomarkers in coronary artery disease patients who are randomised to long-term exercise compared with patients randomised to usual care (control group). Moreover, the investigators will compare fibrinolytic biomarkers assessed at baseline and after three months of supervised exercise for every patient.

    3 months

  • Changes in clot maximum absorbance using the clot lysis assay.

    Changes in maximum absorbance in coronary artery disease patients who are randomised to long-term exercise compared with patients randomised to usual care (control group). Moreover, the investigators will compare clot maximum absorbance assessed at baseline and after three months of supervised exercise for every patient.

    3 months

  • Changes in clot lysis time using the clot lysis assay.

    Changes in clot lysis time in coronary artery disease patients who are randomised to long-term exercise compared with patients randomised to usual care (control group). Moreover, the investigators will compare clot lysis time assessed at baseline and after three months of supervised exercise for every patient.

    3 months

  • Changes in area under the curve using the clot lysis assay.

    Changes in area under the curve in coronary artery disease patients who are randomised to long-term exercise compared with patients randomised to usual care (control group). Moreover, the investigators will compare area under the curve assessed at baseline and after three months of supervised exercise for every patient.

    3 months

Secondary Outcomes (9)

  • Changes in platelet aggregation using arachidonic acid (ASPI) as agonist.

    3 months

  • Changes in platelet aggregation using adenosine diphosphate (ADP) as agonist.

    3 months

  • Changes in platelet aggregation using thrombin receptor activating peptide-6 (TRAP) as agonist.

    3 months

  • Changes in thrombin generation assessing lag-time until initial thrombin generation.

    3 months

  • Changes in thrombin generation assessing maximum concentration of thrombin.

    3 months

  • +4 more secondary outcomes

Other Outcomes (4)

  • Changes in cardiorespiratory performance: maximal oxygen uptake

    3 months

  • Changes in cardiorespiratory performance: maximal power output

    3 months

  • Changes in physical health and mental health (quality of life) assessed by the SF-36v2 questionnaire.

    3 months

  • +1 more other outcomes

Study Arms (2)

Long-term exercise

EXPERIMENTAL

Supervised exercise training three times a week for three months.

Other: Long-term exercise

Usual care

NO INTERVENTION

Patients are not offered supervised exercise.

Interventions

All patients randomised to long-term exercise will perform exercise training at least three times a week for three months. The exercise is supervised and individualised.
