    Abstract:
    BACKGROUND: Standard cardiac rehabilitation (CR) is insufficient to help patients achieve an active lifestyle. The effects of two advanced and extended behavioral CR interventions on physical activity (PA) and sedentary behavior (SB) were assessed. METHODS: In total, 731 patients with ACS were randomized to 1) 3months of standard CR (CR-only); 2) 3months of standard CR with three pedometer-based, face-to-face PA group counseling sessions followed by 9months of aftercare with three general lifestyle, face-to-face group counseling sessions (CR+F); or 3) 3months of standard CR, followed by 9months of aftercare with five to six general lifestyle, telephonic counseling sessions (CR+T). An accelerometer recorded PA and SB at randomization, 3months, 12months, and 18months. RESULTS: The CR+F group did not improve their moderate-to-vigorous intensity PA (MVPA) or SB time compared to CR-only (between-group difference=0.24% MVPA, P=0.349; and 0.39% SB, P=0.529). However, step count (between-group difference=513 steps/day, P=0.021) and time in prolonged MVPA (OR=2.14, P=0.054) improved at 3months as compared to CR-only. The improvement in prolonged MVPA was maintained at 18months (OR=1.91, P=0.033). The CR+T group did not improve PA or SB compared to CR-only. CONCLUSIONS: Adding three pedometer-based, face-to-face group PA counseling sessions to standard CR increased daily step count and time in prolonged MVPA. The latter persisted at 18months. A telephonic after-care program did not improve PA or SB. Although after-care should be optimized to improve long-term adherence, face-to-face group counseling with objective PA feedback should be added to standard CR.
