To investigate the knowledge, attitude and practice (KAP) of patients with ischaemia with non-obstructive coronary arteries (INOCA) toward their condition.
A cross-sectional study using questionnaires to assess KAP scores among patients with INOCA.
Patients with INOCA from the Xinjiang region of China were enrolled between September 2023 and February 2024.
Data were collected via structured questionnaires covering demographic information and KAP metrics.
Mean KAP scores were analysed. Correlation analyses and path analysis examined relationships among KAP components, influencing factors and indirect effects.
A total of 498 questionnaires were analysed (mean age of participants 54.13±10.91, 59.04% women). The mean KAP scores were 4.41±1.78 (possible range: 0-7 points), 21.29±3.40 (possible range: 6-30 points) and 26.91±6.37 (possible range: 8-40 points), respectively. Spearman correlation analysis found significant correlations between knowledge and attitude (r=0.4954, p<0.001), knowledge and practice (r=0.4589, p<0.001) and attitude and practice (r=0.5959, p<0.001). Path analysis indicated that attitude, income and drinking had direct effects on practice. Knowledge influenced practice both directly and indirectly. Indirect effects on practice were also noted for family history of INOCA, residence, marital status, coronary vascular examination and smoking.
This study reveals suboptimal KAP levels among patients with INOCA in Xinjiang, China, highlighting an urgent need for improved patient education and disease management strategies to enhance understanding and coping with INOCA.
调查非阻塞性冠状动脉缺血（INOCA）患者对自身病情的知识、态度和行为（KAP）。
采用问卷调查的横断面研究，以评估INOCA患者的KAP得分。
2023年9月至2024年2月期间纳入了中国新疆地区的INOCA患者。
通过结构化问卷收集数据，内容涵盖人口统计学信息和KAP指标。
分析KAP平均得分。相关性分析和路径分析考察了KAP各成分、影响因素及间接效应之间的关系。
共分析了498份问卷（参与者平均年龄54.13±10.91岁，女性占59.04%）。KAP平均得分分别为4.41±1.78（可能范围：0 - 7分）、21.29±3.40（可能范围：6 - 30分）和26.91±6.37（可能范围：8 - 40分）。Spearman相关性分析发现，知识与态度之间存在显著相关性（r = 0.4954，p < 0.001），知识与行为之间存在显著相关性（r = 0.4589，p < 0.001），态度与行为之间存在显著相关性（r = 0.5959，p < 0.001）。路径分析表明，态度、收入和饮酒对行为有直接影响。知识对行为既有直接影响，也有间接影响。INOCA家族史、居住地、婚姻状况、冠状动脉血管检查和吸烟对行为也有间接影响。
本研究揭示了中国新疆INOCA患者的KAP水平欠佳，凸显迫切需要改进患者教育和疾病管理策略，以增强对INOCA的理解和应对能力。
