Following coronary artery bypass graft (CABG) surgery, some patients experience psycho-mental problems such as hopelessness. The Phase 2 cardiac rehabilitation (CR) program is an important element of the secondary prevention program in treating patients with cardiovascular disease (CVD). The present study aimed to determine the effect of the Phase 2 CR program on the level of hope in cardiac patients after CABG surgery.
A clinical trial was conducted from July 2017 to late January 2018 at the Heart Surgery Centre, Al-Zahra Hospital, Shiraz, Iran. The target population was patients who sought CR therapy after CABG surgery. A total of 104 cardiac patients were recruited and equally divided into control and intervention groups. The intervention group received 20 sessions of Phase 2 CR program combined with education and counselling during 8 weeks. The control group only received routine observations and education. The data were collected pre- and post-intervention using a demographic form and the Miller Hope Scale (MHS). Descriptive statistics were expressed as percentages, frequency distribution, mean and standard deviation. Paired -test and independent -test were used for statistical inference. Data were analyzed using the SPSS statistical software (version 23.0) and P values <0.05 were considered statistically significant.
There was no significant difference in the mean score of hope between the control and intervention groups before the intervention. However, a significant difference between the groups was observed post-intervention (P<0.001). The results showed a significant difference in the mean score of hope between pre-intervention (182.36±23.07) and post-intervention (216.94±23.05) in the intervention group (P<0.001), whereas the difference in the control group was not significant (P=0.095). The measured post-intervention effect size was high (1.05).
The Phase 2 CR program combined with education and counseling increased hope in CVD patients after CABG surgery.
冠状动脉旁路移植术（CABG）后，部分患者会出现诸如绝望等心理问题。心脏康复（CR）二期项目是心血管疾病（CVD）患者二级预防项目的重要组成部分。本研究旨在确定CR二期项目对CABG术后心脏疾病患者希望水平的影响。
2017年7月至2018年1月下旬在伊朗设拉子市阿尔-扎赫拉医院心脏外科中心进行了一项临床试验。目标人群为CABG术后寻求CR治疗的患者。共招募了104名心脏疾病患者，并将其平均分为对照组和干预组。干预组在8周内接受了20次CR二期项目，并结合教育与咨询。对照组仅接受常规观察和教育。干预前后使用人口统计学表格和米勒希望量表（MHS）收集数据。描述性统计以百分比、频率分布、均值和标准差表示。配对检验和独立检验用于统计推断。使用SPSS统计软件（版本23.0）进行数据分析，P值<0.05被认为具有统计学意义。
干预前，对照组和干预组的希望平均得分无显著差异。然而，干预后两组间观察到显著差异（P<0.001）。结果显示，干预组干预前（182.36±23.07）和干预后（216.94±23.05）的希望平均得分存在显著差异（P<0.001），而对照组差异不显著（P=0.095）。干预后测得的效应量较高（1.05）。
CR二期项目结合教育与咨询提高了CABG术后CVD患者的希望水平。
