This study aimed to investigate knowledge, attitude, and practice (KAP) toward coronary heart disease (CHD) secondary prevention among CHD patients.
This web-based cross-sectional study enrolled patients with CHD who visited the Yangpu District Central Hospital in Shanghai (China) between October 18, 2022, and March 25, 2023. The administered questionnaire assessed demographic information and KAP; factors associated with good practice were identified by multivariate logistic regression.
A total of 507 participants were included in the study, with 361 (71.2%) being male. In terms of education, 125 (24.7%) had a junior high school level or below. The mean scores for knowledge, attitudes, and practices were 31.28 ± 7.30 (possible range: 0-42), 54.09 ± 3.33 (possible range: 12-60), and 35.48 ± 3.36 (possible range: 11-55), respectively. For specific knowledge items on CHD, 57.6% of participants correctly identified that women are more susceptible to CHD. Physical labor and emotional excitement as triggers for CHD were correctly recognized by 94.1%. The need for long-term medication and follow-up after a CHD diagnosis had the highest correctness rate at 98.8%. Additionally, 84.6% correctly understood that recurrence of CHD is possible after PCI surgery. Multivariate analysis indicated that smoking and diabetes status were significantly associated with Practice scores. Current smokers reported lower practice levels than never smokers (OR = 2.858, 95% CI: 1.442-5.662, P = 0.003). Participants with diabetes reported higher practice levels than those without diabetes (OR = 4.169, 95% CI: 2.329-7.463, P < 0.001).
Patients with CHD in Shanghai, China, demonstrated good knowledge and positive attitudes toward CHD secondary prevention, although there were some gaps in actual practice behaviors. Enhancing targeted educational interventions and support systems in clinical settings may help bridge these gaps and improve adherence to recommended preventive practices.
本研究旨在调查冠心病（CHD）患者对冠心病二级预防的知识、态度和实践（KAP）情况。
这项基于网络的横断面研究纳入了2022年10月18日至2023年3月25日期间在中国上海杨浦区中心医院就诊的冠心病患者。所发放的问卷评估了人口统计学信息和KAP；通过多因素逻辑回归确定与良好实践相关的因素。
本研究共纳入507名参与者，其中361名（71.2%）为男性。在教育程度方面，125名（24.7%）为初中及以下学历。知识、态度和实践的平均得分分别为31.28±7.30（可能范围：0 - 42）、54.09±3.33（可能范围：12 - 60）和35.48±3.36（可能范围：11 - 55）。对于冠心病的具体知识项目，57.6%的参与者正确识别出女性更容易患冠心病。94.1%的参与者正确认识到体力劳动和情绪激动是冠心病的诱发因素。冠心病诊断后需要长期用药和随访的正确率最高，为98.8%。此外，84.6%的参与者正确理解经皮冠状动脉介入治疗（PCI）手术后冠心病有可能复发。多因素分析表明，吸烟和糖尿病状况与实践得分显著相关。当前吸烟者的实践水平低于从不吸烟者（比值比[OR]=2.858，95%置信区间[CI]：1.442 - 5.662，P = 0.003）。患有糖尿病的参与者的实践水平高于未患糖尿病者（OR = 4.169，95% CI：2.329 - 7.463，P < 0.001）。
中国上海的冠心病患者对冠心病二级预防表现出良好的知识和积极的态度，尽管在实际实践行为方面存在一些差距。在临床环境中加强针对性的教育干预和支持系统可能有助于弥补这些差距，并提高对推荐预防措施的依从性。
