Abstract 11021: Cardiac Rehabilitation Improves Risk Factors, Quality of Life and Exercise Capacity in Extreme Old Age
Introduction: Octogenarians are the fastest growing segment of the US population but data concerning cardiac rehabilitation (CR) in this patient group are sparse.
Hypothesis: A 36-session CR program improves risk factor profile, quality of life (QOL) and exercise capacity in patients older than 80 years of age.
Methods: A total of 945 patients were prospectively enrolled in an outpatient CR program. Baseline demographics and risk factors were recorded. Lipid profiles, BMI and QOL scores were documented pre and post CR. Steady state exercise levels (metabolic equivalents - METs) were calculated at each session.
Results: There were 873 patients <80 years (male 73%, mean age 61 ± 10.6) and 72 patients ≥ 80 years (male 64%, mean age 83 ± 2.3). Risk factors were similar in the older and the younger groups. At baseline, octogenarians had lower BMI (Δ3.4, p<0.05), higher mean QOL score (Δ2.2, p<0.05) and lower mean MET levels (Δ0.5, p<0.05) than those <80 years. In both groups, risk factors and QOL improved (see Table) and exercise capacity rose (see Figure). In octogenarians, adjusting for age, gender, diabetes, lung disease, ejection fraction and diastolic dysfunction, METs rose through the end of CR, but less than in the younger group (see Figure).
Conclusion: Octogenarians significantly improve risk factors, well-being and exercise capacity following CR. METs continue to rise through the 36th session suggesting a possible benefit of even longer CR in extreme old age.
