The aim of this study was to assess the effects on exercise performance of supplementing a standard cardiac rehabilitation program with additional exercise programming compared to the standard cardiac rehabilitation program alone in elderly patients after heart surgery.
In this prospective, randomized controlled trial, 60 patients (32 men and 28 women, mean age 73.1 +/- 4.7 years) completed cardiac rehabilitation (initiated 12.2 +/- 4.9 days postsurgery). Subjects were assigned to either a control group (CG, standard cardiac rehabilitation program [n = 19]), or an intervention group (IG, additional walking [n = 19], or cycle ergometry training [n = 22]). A symptom limited cardiopulmonary exercise test and 6-minute walk test (6MWT) were performed before and after 4 weeks of cardiac rehabilitation. The MacNew questionnaire was used to assess quality of life (QOL).
At baseline, no significant differences for peak oxygen uptake ((.)VO2), maximal power output, or the 6MWT were detected between IG and CG. Global QOL was significantly higher in IG. After 4 weeks of cardiac rehabilitation, patients significantly improved in absolute values of the cardiopulmonary exercise test, 6MWT, and QOL scores. Significant differences between groups were found for peak (.)VO2 (IG: 18.2 +/- 3.1 mL x kg x min vs. CG: 16.5 +/- 2.2 mL x kg x min, P < .05); maximal power output (IG: 72.2 +/- 16 W vs. CG: 60.7 +/- 15 W, P < .05); 6MWT (IG: 454.8 +/- 76.3 m vs. CG: 400.5 +/- 75.5 m, P < .05); and QOL global (IG: 6.5 +/- 0.5 vs. CG: 6.3 +/- 0.6, P < .05).
The supplementation of additional walking or cycle exercise training to standard cardiac rehabilitation programming compared to standard cardiac rehabilitation alone in elderly patients after heart surgery leads to significantly better exercise tolerance.
本研究旨在评估在心脏手术后的老年患者中，与单独进行标准心脏康复计划相比，在标准心脏康复计划中增加额外的运动方案对运动表现的影响。
在这项前瞻性、随机对照试验中，60 名患者（32 名男性和 28 名女性，平均年龄 73.1±4.7 岁）完成了心脏康复（术后 12.2±4.9 天开始）。受试者被分配到对照组（CG，标准心脏康复计划[n=19]）或干预组（IG，额外的步行[n=19]或循环测力计训练[n=22]）。在心脏康复 4 周前后进行了症状限制心肺运动试验和 6 分钟步行试验（6MWT）。使用 MacNew 问卷评估生活质量（QOL）。
在基线时，IG 和 CG 之间在峰值摄氧量（.VO2）、最大功率输出或 6MWT 方面没有显著差异。IG 的整体 QOL 明显更高。经过 4 周的心脏康复治疗，患者在心肺运动试验、6MWT 和 QOL 评分的绝对值上均有显著改善。在峰值 VO2（IG：18.2±3.1 mL x kg x min vs. CG：16.5±2.2 mL x kg x min，P<.05）、最大功率输出（IG：72.2±16 W vs. CG：60.7±15 W，P<.05）、6MWT（IG：454.8±76.3 m vs. CG：400.5±75.5 m，P<.05）和 QOL 整体（IG：6.5±0.5 vs. CG：6.3±0.6，P<.05）方面，两组之间存在显著差异。
与单独进行标准心脏康复计划相比，在心脏手术后的老年患者中，增加额外的步行或循环运动训练对标准心脏康复计划编程与单独进行标准心脏康复计划相比，可显著提高运动耐量。
