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.
对62例冠状动脉疾病患者（n = 48例男性；年龄，72±10岁；体重指数，27±4 kg/m²）在心脏康复（CR）18±2个月前后进行的分级心肺运动试验进行了分析。与延迟（≥114天）CR组相比，早期开始CR（<114天）可使峰值代谢当量（METs）有更大幅度的增加（68%±51%对41%±39%，p<0.05）。发现CR延迟与峰值METs之间存在负相关（r = -0.32；p = 0.02）。早期开始CR对于使心肺对慢性运动训练的适应性最大化可能很重要。
