Brief Summary

High-intensity training (HIT) has repeatedly been documented to have superior positive effects compared to moderate exercise in patients with coronary heart disease and heart failure. Since heart transplant recipients (HTx), have a denervated heart with different respond to exercise, HIT has previously not been introduced among these patients. Rikshospitalet carried out a RCT to investigate this (the TEX study 2009-2012), and found that this form of exercise also was highly effective and safe in long term HTx with clinically significant improvement in VO2peak, muscular exercise capasity, general HRQoL, and even slower progression of CAV (coronary allograft vasculopathy). Based on these findings we ask the following questions in this follow-up study:

  1. 1.Would the effect on VO2peak, HRQoL,muscle capacity and CAV obtained during the study period continue during long term follow up (5 years)?
  2. 2.Is the intervention group more physical active after HIT compared to the control group?

Outcome Measures

Primary Outcomes (1)

  • mean VO2peak in the intervention group and control group

    We will use the same test protocol as the TEX- study.

    5 years after start of inclusion in RCT (TEX). One measurment.

Secondary Outcomes (4)

  • How many has progression of cardiac allograft vasculopathy in the intervention group and control group.

    5 years after inclusion in RCT (TEX study).

  • Mean muscle capacity in the intervention group and control group.

    5 years after inclusion in RCT, TEX study.

  • Quality of life

    5 years after inclusion in TEX- study.

  • Difference in activity level between groups

    5 years after inclusion i RCT, TEX study.

Study Arms (2)

Intervention group

Group that followed high- intensity interval training program in TEX study.

Control group

Followed up on a regular basis for HTx recipients in Norway.
