Objective: Present study examines the prevalence of type 2 diabetes
(DM2) in patients attending cardiac rehabilitation (CR) compared to the
general population utilising data from the Icelandic Heart Association
population study. The study also examined the efficacy of CR for pro-
moting health behaviors.
Material and methods: A prospective study among DM2 patients
attending CR at Reykjalundur Rehabilitation centre. The DM2 group was
compared to other cardiac patients, with respect to obesity and exercise
capacity at the beginning and end of 4-6 weeks of CR. Additionally, in
the DM2 group, weight, smoking cessation, physical activity and walking
capacity were assessed at 3 and 6 months follow-ups.
Results: The prevalence of DM2 was 2-4 times higher in CR particip-
ants than in the general population. Compared to other CR participants,
the DM2 group was heavier, with increased waist circumference and
less exercise capacity. During the CR both groups lost weight and waist
circumference decreased to similar extent, but the exercise capacity
increased less in the DM2 group. In follow up after 6 months the DM2
group´s weight and glucose values were back to same level as before
CR, but waist circumference was still decreased and they retained
increased physical activity and walking capacity.
Conclusion: DM2 is more prevalent among patients in cardiac rehabi-
litation than in the general population. The DM2 group was more obese,
had lower exercise capacity and responded somewhat less to CR than
other cardiac patients. Follow up after 6 months did however show that
they continued their regular exercise and walking capacity was still
retained.
