Abstract 17415: Similar Improvements in Outcomes Following 36 Sessions of Cardiac Rehabilitation Irrespective of Duration
Background: Cardiac Rehabilitation (CR) improves functional capacity in patients with CAD. The standard program requires completion of 36 sessions most often in 12 weeks. For various reasons, many patients are unable to complete a CR program in this time. Data comparing outcomes from standard 12-week programs to those of a greater duration are sparse.
Hypothesis: We predicted that patients completing 36 sessions of CR in our standard 12-week program would achieve similar improvements in exercise capacity and risk factors as those taking longer than 12 weeks.
Methods: Between 2004 and 2013, 836 patients (mean age 63.3 ± 11.0 years, 222 females and 614 males) completed 36 sessions of CR in 12-15 weeks (n=507), 15-19 weeks (n=234), or 19-67 weeks (n=95). Exercise capacity in metabolic equivalents (METs) and risk factors were measured before and after CR. Analysis of variance was used to compare groups.
Results: All patients showed similar improvements in exercise capacity, weight, BMI, LDL, and HDL cholesterol (see table and figure). Systolic pressures decreased, though not significantly, but diastolic pressures remained unchanged.
Conclusion: Although standard of care for CR is usually to complete 36 sessions in 12 weeks, a longer program incorporating the same number of sessions may achieve similar outcomes in relation to exercise capacity and risk factors, with the exception of blood pressure. Such programs may be suitable for patients who are unable to complete a CR program within the standard time frame due to social, occupational, or medical constraints.
