SUMMARY
Introduction/Aim. Cardiovascular rehabilitation (CVR) is of utmost
importance in primary and (especially) in secondary prevention of
coronary artery disease (CAD). The aim of our paper was to examine
whether elderly patients with CAD benefit equally from CVR program as
CAD patients of younger age.
Methods. The study involved 1,697 patients referred to the CVR program
after surviving myocardial infarction, percutaneous coronary
intervention or surgical myocardial revascularization. Patients were
divided in two groups: group I involved patients younger than 65 years
(1099 patients, 64.76%), whereas group II comprised patients 65 years
old or older (598 patients, 35.24%). At the beginning and at the end of
CVR, exercise stress tests were done (EST1 and EST2). Also, the quality
of life (QOL) was assessed at the beginning and at the end of CVR by
validated questionnaire Short-Form 36 Health Status Survey (SF-36). The
results were compared between the groups.
Results. Younger patients showed better exercise tolerance on EST1 and
EST2. However, both groups showed better exercise tolerance on EST2.
Namely, in both groups, patients achieved higher strain level and longer
duration on EST2 compared to EST1.
Also, higher percentage of patients finished the test by
achieving submaximal heart rate on EST2 compared to EST1. Also, our
patients showed a significant improvement in all QOL areas except
emotional health of patients ≥ 65 of age due to borderline statistically
significant limitation.
Conclusion. Our study showed that CVR improves the quality of life and
physical exercise tolerance in elderly CAD patients. This is why the
utilization rate and adherence of these patients to CVR programs should
be vigorously encouraged.
