To determine the effect mobile messaging apps on coronary artery disease patient knowledge of and adherence to a healthy lifestyle.
Due to the increasing incidence of coronary artery disease in recent years, interventions targeting coronary artery disease risk factors are urgent public priorities. The use of mobile technology in healthcare services and medical education is relatively new with promising future prospects.
This study used a quasiexperimental design that included pre- and posttest for intervention and control groups.
The study was conducted from January-April 2017 with both intervention and control groups, in a teaching hospital in Klang Valley. Convenience sampling was used with inclusive criteria in choosing the 94 patients with coronary artery disease (intervention group: 47 patients; control group: 47 patients). The pretest was conducted as a baseline measurement for both groups before they were given standard care from a hospital. However, only the intervention group was given a daily information update via WhatsApp for 1 month. After 1 month, both groups were assessed with a posttest.
The split-plot ANOVA analysis indicates that there is a significant and positive effect of the intervention on coronary artery disease patients' knowledge on coronary artery disease risk factors [F(1, 92) = 168.15, p < 0.001] with a large effect size ( = 0.65). The mobile messaging apps also significantly improve the patients' adherence to a healthy lifestyle [F(1, 92) = 83.75, p < 0.001] with a large effect size ( = 0.48).
This study concluded that WhatsApp was an effective health intervention in increasing coronary artery disease patient's knowledge and subsequently increasing their adherence to healthy lifestyles.
In clinical setting, mobile messaging apps are useful in information delivery and efficient patient monitory.
确定移动消息应用程序对冠心病患者健康生活方式知识及依从性的影响。
近年来，由于冠心病发病率不断上升，针对冠心病危险因素的干预措施成为当务之急。移动技术在医疗服务和医学教育中的应用相对较新，前景广阔。
本研究采用准实验设计，对干预组和对照组进行前后测。
2017年1月至4月，在巴生谷的一家教学医院对干预组和对照组进行了研究。采用便利抽样法，根据纳入标准选取了94例冠心病患者（干预组：47例患者；对照组：47例患者）。在两组患者接受医院标准护理前，进行前测作为基线测量。然而，仅对干预组通过WhatsApp每日提供信息更新，为期1个月。1个月后，对两组进行后测评估。
裂区方差分析表明，干预对冠心病患者冠心病危险因素知识有显著的正向影响[F(1, 92) = 168.15, p < 0.001]，效应量较大（ = 0.65）。移动消息应用程序还显著提高了患者对健康生活方式的依从性[F(1, 92) = 83.75, p < 0.001]，效应量较大（ = 0.48）。
本研究得出结论，WhatsApp是一种有效的健康干预措施，可增加冠心病患者的知识，进而提高他们对健康生活方式的依从性。
在临床环境中，移动消息应用程序有助于信息传递和有效的患者监测。
