[Effects of a cardiac rehabilitation programme in coronary patient according to age]

Benefits of cardiac rehabilitation (CR) are well established in coronary heart disease. The effects according to age are less known, especially in France.

Evaluation at 6 months of a CR programme in three groups of patients with different age.

Two hundred and two coronary patients were included in the CR department in Machecoul between 2007 and 2009. They attended the CR programme and were examined at six months. Patients were divided into three groups: group 1, n=103 (<65 years), group 2, n=71 (65 to 75 years) and group 3, n=28 (>75 years). We analysed the exercise capacity (exercise stress testing and six minutes walk-test or 6MWT), two questionnaires (dietary and physical activity) and bio-clinical data.

Exercise capacity improved respectively by 24, 27 and 18% (P<0.004 between G2 and G3). The 6MWT improved by 19, 22 and 25% (P<0.01 between G1 and G3). At 6 months, the 6MWT remain stable, the dietary and physical activity scales improved in the three groups, the body mass index (BMI) was unchanged, HDL cholesterol increased, smoking prevalence was respectively 16, 0 and 0% and medical treatment were optimal in 90, 82 and 79% (NS).

If the impact of CR was almost similar in the three groups, a more prolonged physical training seems desirable in patients over 75 years.
