Coronary artery disease is one of the main causes of mortality and morbidity among chronic heart diseases worldwide. Patients reported chronic chest pain as the primary symptom of coronary artery disease. Due to its progressive nature, it affects the health status and functional capacity of the patients. The current study was planned to compare the effects of prehabilitation resistance training in mild to moderate clinically frail patients awaiting coronary artery bypass graft (CABG). A randomized controlled trial was conducted on 74 patients awaiting CABG at the Faisalabad Institute of Cardiology, Faisalabad, Pakistan. A Modified Healthy Heart Questionnaire was used for screening of the patients. Interventions applied were resistance training by using cuff weights/dumbbells at light intensity (40%-50%) of a maximum of one repetition (10-15 repetitions for one to three times a day) per major muscle groups of upper and lower limbs of the body on weekly basis. The main outcome measures were the 6-minute walk test (6MWT), the New York Heart Association (NYHA) for heart failure, the clinical frailty score, and the essential frailty toolset. Significant differences between group A (resistance training group) and group B (conventional physical therapy group) patients were observed. The mean ranks for 6MWT in group A and group B were 1.70 and 1.55, respectively. The mean ranks of NYHA in group A and group B were 1.68 and 2.84, respectively. Clinical frailty scores in group A and group B were 2.68 and 2.74, respectively, with the essential frailty toolset in group A and group B were 1.14 and 1.11, respectively. There were significant (p < 0.05) differences within and between groups for prehabilitation resistance training after CABG. The study showed that the resistance training group had improved the clinical frailty score, strength, endurance, and functional capacity in patients who underwent elective CABG.
冠状动脉疾病是全球慢性心脏病中导致死亡和发病的主要原因之一。患者报告慢性胸痛是冠状动脉疾病的主要症状。由于其渐进性，它会影响患者的健康状况和功能能力。本研究旨在比较术前康复抗阻训练对等待冠状动脉旁路移植术（CABG）的轻度至中度临床虚弱患者的影响。在巴基斯坦费萨拉巴德的费萨拉巴德心脏病学研究所，对74名等待CABG的患者进行了一项随机对照试验。使用改良的健康心脏问卷对患者进行筛查。干预措施为每周对身体上下肢的主要肌肉群进行一次轻强度（40%-50%）的抗阻训练，使用袖带重物/哑铃，每组最多重复一次（每天一到三次，每次10-15次重复）。主要结局指标为6分钟步行试验（6MWT）、纽约心脏协会（NYHA）心力衰竭分级、临床虚弱评分和基本虚弱工具集。观察到A组（抗阻训练组）和B组（传统物理治疗组）患者之间存在显著差异。A组和B组6MWT的平均秩分别为1.70和1.55。A组和B组NYHA的平均秩分别为1.68和2.84。A组和B组的临床虚弱评分分别为2.68和2.74，A组和B组的基本虚弱工具集分别为1.14和1.ll。CABG术后术前康复抗阻训练在组内和组间均存在显著（p<0.05）差异。研究表明，抗阻训练组改善了接受择期CABG患者的临床虚弱评分、力量、耐力和功能能力。
