To assess the clinical impact of a cardiac rehabilitation program in an older population.This is a retrospective analysis of 731 coronary patients who attended phase 2 of a cardiac rehabilitation program between January 2009 and December 2016. We compared the response to the program of older (≥65 years) and younger (<65 years) patients, analyzing changes in metabolic profile (including body mass index, waist circumference and lipid profile), exercise capacity, cardiac autonomic regulation parameters (such as chronotropic index and resting heart rate), and health-related quality of life scores.Older patients represented 15.9% of our cohort. They showed significant reductions in waist circumference (male patients: 98.0±7.9 cm vs. 95.9±7.9 cm, p<0.001; female patients: 90.5±11.4 cm vs. 87.2±11.7 cm, p<0.001), LDL cholesterol (102.5 [86.3-128.0] mg/dl vs. 65.0 [55.0-86.0] mg/dl, p<0.001) and triglycerides (115.0 [87.8-148.5] mg/dl vs. 97.0 [81.8-130.0] mg/dl, p<0.001). Post-training data also showed a noticeable improvement in older patients' exercise capacity (7.6±1.8 METs vs. 9.3±1.8 METs, p<0.001), along with a higher chronotropic index and lower resting heart rate. Additionally, health-related quality of life indices improved in older subjects. However, our overall analysis found no significant differences between the groups in changes of the studied parameters.Older coronary patients benefit from cardiac rehabilitation interventions, similarly to their younger counterparts. Greater involvement of elderly patients in cardiac rehabilitation is needed to fully realize the therapeutic and secondary preventive potential of such programs.
