Abstract

Background: Despite the known benefits of cardiac rehabilitation (CR) for patients with stable coronary artery disease, it isneglected, especially in women. Home-based programmes may increase adherence to CR.

Aim: To compare the effectiveness of centre-based CR with a hybrid model of training, partly out-patient and partly home-basedand tele-monitored, in terms of physical capacity and adherence in post-myocardial infarction (MI) women with preservedleft ventricular function.

Methods: 53 post-MI female patients, aged 51.3 ± 7.6 years underwent an eight-week training programme (TP) consisting of 24 interval trainings. The first ten trainings were performed in a hospital, then 33 patients (Gruop A) continued themin the centre, the remaining 20 (Group B) did tele-monitored walking training at home (hybrid model). Before and after completing CR, all patients underwent a symptom-limited treadmill exercise stress test during which the analysis included: workload (METs), duration (min), heart rate (HR, bpm), double product (mm Hg/min) at rest and during effort, and HR recovery in the first minute after test. Adherence was reported as the number of trainings completed and the number of dropouts in two CR models.

Results: After CR, only workload (Group A: 6.5 ± 1.1 vs. 7.0 ± 1.4, p < 0.05; Group B: 7.4 ± 1.1 vs. 8.3 ± 1.4, p < 0.01) and duration (Group A: 4.7 ± 1.1 vs. 5.1 ± 1.2, p < 0.01; Group B: 8.1 ± 3.9 vs. 9.3 ± 4.2, p < 0.01) improved significantly in both groups. Comparing CR effects between both groups, no significant differences were observed. All patients completed TP.

Conclusions: In post-MI women, a hybrid model of training improved physical capacity and was a similarly effective form of CR as a centre-based approach. A home-based tele-monitored programme facilitated our patients’ adherence to CR.
