Coronary heart disease (CHD) is a leading cause of mortality worldwide. Coronary artery bypass grafting (CABG) is a recognized effective treatment, particularly for patients with complex multivessel disease. However, there is limited research on the knowledge, attitudes, and practices (KAP) of CHD patients toward this surgery.
This study aimed to investigate the KAP of CHD patients regarding CABG.
A cross-sectional study was conducted from September 13, 2023 to January 25, 2024 at the Cardiology and Cardiothoracic Surgery Departments of Zhengzhou Seventh People's Hospital through the dissemination of a self-designed KAP questionnaire, which demonstrated good internal consistency with a Cronbach's α coefficient of 0.921 in the pilot test.
A total of 427 participants (mean age 58.05 ± 13.2 years; 62.53% male) were enrolled. Among them, 151 (35.36%) had undergone or are scheduled for CABG. The mean knowledge, attitude, and practice scores were 6.03±2.16, 43.03±6.61, and 37.7±5.51, respectively. Participants with CABG experience or plans exhibited significantly higher attitude and knowledge scores compared to those without. Correlation analyses showed that there were significant positive correlations between knowledge and attitude (r = 0.128, P = 0.008) as well as practice (r = 0.202, P < 0.001). Also, there was a correlation between attitude and practice (r = 0.654, P < 0.001). Multivariate analyses showed that attitude score (OR = 1.294, 95% CI: [1.226-1.367], P < 0.001), marital status other than married (OR = 2.32, 95% CI: [1.048-5.136], P = 0.038) were independently associated with proactive practice.
CHD patients exhibited insufficient knowledge, positive attitudes and proactive practices regarding CABG. Healthcare professionals should prioritize patient education initiatives aimed at enhancing knowledge regarding CABG, while also reinforcing and leveraging positive attitudes and proactive behaviors to optimize patient outcomes and treatment adherence.
冠心病（CHD）是全球主要的死亡原因之一。冠状动脉旁路移植术（CABG）是一种公认的有效治疗方法，尤其适用于患有复杂多支血管病变的患者。然而，关于冠心病患者对该手术的知识、态度和实践（KAP）的研究有限。
本研究旨在调查冠心病患者对冠状动脉旁路移植术的KAP情况。
2023年9月13日至2024年1月25日，在郑州市第七人民医院心内科和心胸外科进行了一项横断面研究，通过发放自行设计的KAP问卷进行调查，该问卷在预试验中的Cronbach's α系数为0.921，显示出良好的内部一致性。
共纳入427名参与者（平均年龄58.05±13.2岁；男性占62.53%）。其中，151人（35.36%）已经接受或计划接受冠状动脉旁路移植术。知识、态度和实践得分的平均值分别为6.03±2.16、43.03±6.61和37.7±5.51。有冠状动脉旁路移植术经验或计划的参与者在态度和知识得分上显著高于没有的参与者。相关性分析表明，知识与态度之间存在显著正相关（r = 0.128，P = 0.008）以及与实践之间存在显著正相关（r = 0.202，P < 0.001）。此外，态度与实践之间也存在相关性（r = 0.654，P < 0.001）。多变量分析表明，态度得分（OR = 1.294，95%CI：[1.226 - 1.367]，P < 0.001）、非已婚婚姻状况（OR = 2.32，95%CI：[1.048 - 5.136]，P = 0.038）与积极实践独立相关。
冠心病患者对冠状动脉旁路移植术的知识不足，但态度积极且实践主动。医疗保健专业人员应优先开展患者教育活动，以增强对冠状动脉旁路移植术的了解，同时加强和利用积极态度及主动行为，以优化患者治疗效果和治疗依从性。
