BACKGROUND
This study aimed to assess the effectiveness of an interactive avatar application in enhancing self-care behaviors and improving recognition and response to heart attack symptoms among patients with Acute Coronary Syndrome (ACS).
METHODS
A non-blinded, two-arm, randomized controlled trial was conducted with 78 ACS patients randomly allocated to either an intervention group or a control group. The control group received conventional education, while the intervention group received conventional education supplemented with training via an interactive avatar application. The application provided guidance on self-care practices, recognition of heart attack symptoms, and appropriate responses. Data were collected at baseline, 1 month, and 3 months post-discharge using demographic questionnaires, the Self-Care of Coronary Heart Disease Inventory, and the ACS Response Index. Statistical analyses included chi-square tests, independent samples t-tests, and Mann-Whitney U tests.
RESULTS
At the 3-month follow-up, participants in the intervention group exhibited significantly higher scores on both the Self-Care of Coronary Heart Disease Inventory and ACS Response Index compared to the control group (P < 0.05). Furthermore, during the 3-month follow-up period, all patients in the intervention group (100%) ceased activity and took sublingual nitroglycerin upon experiencing heart attack symptoms, compared to 80% in the control group.
CONCLUSIONS
The interactive avatar application proved effective in improving knowledge, attitudes, beliefs, and self-care behaviors among ACS patients. This innovative educational tool holds promise for enhancing patient outcomes in ACS management.

背景
本研究旨在评估交互式虚拟化身应用程序在增强急性冠状动脉综合征（ACS）患者的自我护理行为以及提高其对心脏病发作症状的识别和反应能力方面的有效性。
方法
对78例ACS患者进行了一项非盲、双臂、随机对照试验，将患者随机分为干预组或对照组。对照组接受常规教育，而干预组在接受常规教育的同时，通过交互式虚拟化身应用程序接受培训。该应用程序提供了自我护理实践、心脏病发作症状识别和适当应对措施的指导。在出院后基线、1个月和3个月时，使用人口统计学问卷、冠心病自我护理量表和ACS反应指数收集数据。统计分析包括卡方检验、独立样本t检验和曼-惠特尼U检验。
结果
在3个月的随访中，干预组参与者在冠心病自我护理量表和ACS反应指数上的得分均显著高于对照组（P<0.05）。此外，在3个月的随访期间，干预组所有患者（100%）在出现心脏病发作症状时均停止活动并舌下含服硝酸甘油，而对照组这一比例为80%。
结论
交互式虚拟化身应用程序被证明在改善ACS患者的知识、态度、信念和自我护理行为方面是有效的。这种创新的教育工具有望改善ACS管理中的患者预后。
