Coronary artery disease (CAD) is the leading cause of death worldwide. Lifestyle change is a crucial part of secondary prevention. Only 30% of CAD patients follow the corresponding guideline recommendations. The widespread adoption of smartphones offers the opportunity to integrate secondary prevention into the daily routine of CAD patients.
We developed an app to integrate secondary prevention into CAD patients' everyday life (smartphone-guided secondary prevention, SGSP). The app provided a daily 15-minute program that included video-guided exercises, video sessions with background information about CAD, and a tool to record blood pressure and heart rate once a day. The SGSP app was tested with the primary outcome of 28-day adherence. The secondary outcome was a composite of (1) self-reported behavioral changes, (2) gain of knowledge about cardiovascular risk factors, and (3) an increase in quality of life.
Of the 66 patients screened, 43 (65%) were included into the study and, of those, 17 (40%) used the app continuously for 28 days. From this group, 14 (82%) were physically more active and ten (59%) improved their dietary habits. Usage of the SGSP app was also associated with a gain of knowledge about cardiovascular risk factors (70% physical activity, 59% healthy diet).
The regular use of a SGSP app appears to support lifestyle changes in patients with CAD.
冠状动脉疾病（CAD）是全球主要的死亡原因。生活方式改变是二级预防的关键部分。只有30%的CAD患者遵循相应的指南建议。智能手机的广泛应用为将二级预防融入CAD患者的日常生活提供了契机。
我们开发了一款应用程序，将二级预防融入CAD患者的日常生活（智能手机引导的二级预防，SGSP）。该应用程序提供每日15分钟的计划，包括视频引导的锻炼、有关CAD背景信息的视频课程，以及每天记录一次血压和心率的工具。对SGSP应用程序进行了测试，主要结局为28天的依从性。次要结局包括：（1）自我报告的行为改变；（2）心血管危险因素知识的增加；（3）生活质量的提高。
在筛查的66例患者中，43例（65%）纳入研究，其中17例（40%）连续28天使用该应用程序。在这组患者中，14例（82%）身体活动增多，10例（59%）饮食习惯改善。使用SGSP应用程序还与心血管危险因素知识的增加相关（身体活动方面为70%，健康饮食方面为59%）。
定期使用SGSP应用程序似乎有助于CAD患者改变生活方式。
