Long-term maintenance-phase cardiac rehabilitation provides clinically significant improvements in cardiorespiratory fitness regardless of the delay in enrolment following a cardiovascular event.
Purpose: This study investigated if associations exist between enrolment delay and VO 2 peak over five years of maintenance-phase cardiac rehabilitation (CR) in males and females. Method: Data were extracted from the records of participants who had enrolled for ≥ 1 year in CR and completed ≥ 2 cardiopulmonary exercise tests. Mixed model analyses examined VO 2 peak trajectories for up to five years of enrolment. Interactions between enrolment delay × enrolment duration, baseline age × enrolment duration, and baseline VO 2 peak × enrolment duration were explored for inclusion in the model. Results: The charts of 151 males (aged 63.9 ± 9.4 y) and 32 females (aged 65.3 ± 9.0 y) were included in the analyses. The enrolment delay following a cardiovascular event was 1.8 ± 3.0 years for males and 1.3 ± 1.7 years for females. No associations were found between enrolment delay × enrolment duration on VO 2 peak in males (β[SEj, 0.07[0.05]; 95% CI −0.02, 0.16, p = 0.12) or in females (β[SE], 0.07[0.13j; 95% CI −0.18, 0.33, p = 0.57), but predicted trajectories suggest clinically significantly improvements in VO 2 peak (range, 1.3 to 1.6 mL/kg/min). Conclusions: Early enrolment in CR is recommended and encouraged, but the benefits of long-term CR are possible despite delays.

Moncion et al. (2022) conducted a cohort in cardiovascular event (n=183). Enrolment delay was evaluated on VO2 peak trajectories over up to five years (β 0.07 (males); β 0.07 (females), 95% CI -0.02 to 0.16 (males); -0.18 to 0.33 (females), p=0.12 (males); 0.57 (females)). Enrolment delay in maintenance-phase cardiac rehabilitation was not associated with VO2 peak trajectories over five years in males or females.
