Objective. Examining the effects of a pulmonary rehabilitation (PR) program applied to patients undergoing coronary artery bypass grafting (CABG) surgery with open heart technique on respiratory functions, functional capacity, and quality of life (QoL). Design. This randomised controlled study applied the Consolidated Standards of Reporting Trials statement. Methods. The study was conducted with two groups: the intervention group () and the control group (). The control group received standard care after coronary artery bypass grafting. On the contrary, the experimental group participated in a PR program created by the researchers in addition to standard care. After coronary artery bypass grafting, the respiratory functions (on the 4th day of clinical care) and QoL (at the 6^th week) of both groups were evaluated. The primary outcome measure was the respiratory function (forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC). The secondary outcome measure of this study was the QoL. Results. When the average pulmonary function test values of the patients were examined, the mean FVC and FEV1 values of the patients in the intervention group on the 4th day of clinical care were significantly higher with a medium level size effect than the control group (; effect size ; ; effect size , respectively). At the postoperative 6th week measurement of QoL, a decrease was observed in all subdimensions of the scale, albeit less in the intervention group (). There was a decrease in both the mental and physical component summary of QoL (). Conclusion. The results of this study revealed that pulmonary rehabilitation applied to patients who have undergone coronary artery bypass graft recover their functional capacity faster.

冠状动脉旁路移植术后肺康复对呼吸功能和生活质量的影响：一项随机对照研究

客观。检查肺康复 (PR) 计划应用于接受心脏直视技术进行冠状动脉旁路移植术 (CABG) 手术的患者对呼吸功能、功能能力和生活质量 (QoL) 的影响。设计。这项随机对照研究应用了报告试验综合标准声明。方法。该研究分为两组：干预组（)和对照组 (）。对照组在冠状动脉旁路移植术后接受标准治疗。相反，实验组除了标准护理外，还参加了研究人员创建的公关项目。冠状动脉旁路移植术后，评估两组的呼吸功能（临床护理第4天）和生活质量（第6周）^。主要结局指标是呼吸功能（一秒用力呼气量 (FEV1)、用力肺活量 (FVC) 和 FEV1/FVC）。本研究的次要结果测量是生活质量。结果. 检查患者平均肺功能检测值时，干预组患者在临床护理第 4 天的平均 FVC 和 FEV1 值显着高于对照组，具有中等大小效应（; 规模效应; ; 规模效应，分别）。在术后第 6 周的生活质量测量中，观察到量表的所有子维度都有下降，尽管干预组的下降幅度较小（）。QoL 的心理和身体成分汇总均有所下降（）。 结论。这项研究的结果表明，肺康复应用于接受冠状动脉旁路移植术的患者恢复其功能能力的速度更快。
