The effectiveness of gamification-based feedback systems that utilize non-monetary points to promote exercise among cardiovascular disease (CVD) patients has not been fully evaluated. This study aimed to evaluate the effectiveness of a gamification program using non-monetary points on the daily step counts in CVD patients. We collected 30 patients with a history of heart failure or myocardial infarction at a single tertiary center between January 9, 2023, and April 13, 2023. The primary outcome was the change in daily step counts. The baseline step counts were compared with those during the 4-week gamification and the 1-week follow-up period. A total of 29 participants with a mean age of 64.6 years were finally enrolled, and 8 (27.6%) were female. Among them, 23 (79.3%) had a history of old myocardial infarction, and 9 (31.0%) had a history of chronic heart failure. During the intervention period, the average daily step counts increased significantly from baseline in weeks 1-5 (week 1: 1165 steps; 95% CI, 319-2011; P = 0.009, week 2: 1508; 635-2382; P = 0.001, week 3: 1321; 646-1996; P < 0.001, week 4: 1436; 791-2081; P < 0.001, week 5:1148; 436-1860; P < 0.001). Higher body mass index was statistically associated with the smaller difference in step counts from the baseline, and the lower proportion of achievement of step count goals. Female sex was significantly associated with the higher proportion of achievement of step count goals. In conclusion, this pilot prospective interventional study demonstrated the effectiveness of gamification-based feedback systems that utilize non-monetary points to increase daily step counts in CVD patients.

基于游戏化的反馈系统利用非货币积分来促进心血管疾病 (CVD) 患者的锻炼，其有效性尚未得到充分评估。本研究旨在评估使用非货币积分的游戏化计划对 CVD 患者每日步数的有效性。我们收集了 2023 年 1 月 9 日至 2023 年 4 月 13 日期间在单个三级中心有心力衰竭或心肌梗死病史的 30 名患者。主要结果是每日步数的变化。将基线步数与 4 周游戏化和 1 周随访期间的步数进行比较。最终共有 29 名参与者平均年龄 64.6 岁入组，其中 8 名（27.6%）为女性。其中，23例（79.3%）有陈旧性心肌梗死病史，9例（31.0%）有慢性心力衰竭病史。在干预期间，第 1-5 周的平均每日步数较基线显着增加（第 1 周：1165 步；95% CI，319-2011；P = 0.009，第 2 周：1508；635-2382；P = 0.001 ，第 3 周：1321；646-1996；P < 0.001，第 4 周：1436；791-2081；P < 0.001，第 5 周：1148；436-1860；P < 0.001）。较高的体重指数与步数与基线的较小差异以及实现步数目标的比例较低存在统计学相关性。女性性别与实现步数目标的较高比例显着相关。总之，这项试点前瞻性干预研究证明了基于游戏化的反馈系统的有效性，该系统利用非货币积分来增加 CVD 患者的每日步数。
