Why the study?
Does early initiation of cardiac rehabilitation improve peak metabolic equivalents in coronary artery disease patients?
Does early initiation of cardiac rehabilitation improve peak metabolic equivalents in coronary artery disease patients?
Early initiation of cardiac rehabilitation (<114 days) significantly improves exercise capacity compared to late initiation in patients with coronary artery disease.
May support earlier CR referral to maximize MET gains in CAD; hypothesis-generating, requires RCTs to confirm.
Graded cardiopulmonary exercise tests were analyzed from 62 coronary artery disease patients (n = 48 males; age, 72 ± 10 years; body mass index, 27 ± 4 kg/m(2)) before and after 18 ± 2 months of cardiac rehabilitation (CR). Early initiation of CR (<114 days) produced greater increases in peak metabolic equivalents (METs) compared with the late (≥114 days) CR group (68% ± 51% vs. 41% ± 39%, p < 0.05). A negative correlation was found between CR delay and peak METs (r = -0.32; p = 0.02). Early initiation of CR may be important to maximize cardiorespiratory adaptations to chronic exercise training.
