What is the clinical evidence from this study?

Study design: Observational. Population: Patients enrolled in cardiac rehabilitation (n=778). Intervention: Supervised prescribed exercise (cardiac rehabilitation). Primary outcome: Change in functional capacity (peak MET levels).

What question did this study set out to answer?

To evaluate baseline exercise tolerance and functional capacity changes after supervised cardiac rehabilitation across age and gender strata, particularly in individuals with low initial exercise capacity (<5 METs).

Key result

Supervised cardiac rehabilitation yielded significant relative improvements in exercise tolerance across all age and gender subgroups (32% to 50%), particularly among those with initial peak METs <5.

Why the study?

Key Points

To evaluate baseline exercise tolerance and functional capacity changes after supervised cardiac rehabilitation across age and gender strata, particularly in individuals with low initial exercise capacity (<5 METs).
Prospective multicenter registry study of 778 patients undergoing baseline exercise testing with measurement of peak heart rate, blood pressure, estimated peak METs, and ischemic responses.
A total of 500 patients completed 10 ± 2 weeks of supervised prescribed exercise training and underwent follow-up exercise testing.
Baseline peak exercise tolerance was higher in men (8.6 ± 3.4 METs) than women (6.0 ± 2.6 METs) and declined with advancing age (<65: 8.9 ± 3.4; 65–75: 6.6 ± 2.6; >75: 5.7 ± 2.9 METs; P < 0.0001).
Relative post-training improvements ranged from 32% to 50% across cohorts (<65: men 36%, women 41%; 65–75: men 36%, women 50%; >75: men 36%, women 32%), with no significant net change in exercise-induced ischemia.
Patients starting with peak METs <5 (n=163) significantly improved exercise tolerance from 4.1 ± 0.7 to 8.3 ± 3.5 METs (P < 0.0001), showing the greatest relative gains on multivariate analysis.

Does supervised cardiac rehabilitation improve functional capacity in patients across different age and gender groups?

Population

778 consecutive patients enrolled in supervised cardiac rehabilitation, including 558 men (72%) and 220 women (28%), with 492 (63%) aged <65 years, 241 (31%) aged 65 to 75 years, and 45 (6%) aged >75 years.

Intervention

10 +/- 2 weeks of supervised prescribed exercise (cardiac rehabilitation)

Outcome

Change in functional capacity (estimated peak MET levels) after 10 +/- 2 weeks of supervised exercisesurrogate

Supervised cardiac rehabilitation significantly improves exercise capacity across all age and gender groups, particularly in those with the lowest baseline functional capacity.

Balady et al. (1996) conducted an observational in Patients enrolled in cardiac rehabilitation (n=778). Supervised prescribed exercise (cardiac rehabilitation) was evaluated on Change in functional capacity (peak MET levels). Supervised cardiac rehabilitation yielded significant relative improvements in exercise tolerance across all age and gender subgroups (32% to 50%), particularly among those with initial peak METs <5.
