Patients with heart failure have low quality of life because of physical impairments and advanced clinical symptoms. One of the main goals of caring for patients with heart failure is to improve their quality of life.
The aim of this study was to investigate the effect of the use of a smartphone-based app on the quality of life of patients with heart failure.
This randomized controlled clinical trial with a control group was conducted from June to October 2018 in an urban hospital. In this study, 120 patients with heart failure hospitalized in cardiac care units were randomly allocated to control and intervention groups. Besides routine care, patients in the intervention group received a smartphone-based app and used it every day for 3 months. Both the groups completed the Minnesota Living with Heart Failure Questionnaire before entering the study and at 3 months after entering the study. Data were analyzed using the SPSS software V.16.
The groups showed statistically significant differences in the mean scores of quality of life and its dimensions after the intervention, thereby indicating a better quality of life in the intervention group (P<.001). The effect size of the intervention on the quality of life was 1.85 (95% CI 1.41-2.3). Moreover, the groups showed statistically significant differences in the changes in the quality of life scores and its dimensions (P<.001).
Use of a smartphone-based app can improve the quality of life in patients with heart failure. The results of our study recommend that digital apps be used for improving the management of patients with heart failure.

心力衰竭患者因身体功能受损和严重的临床症状而生活质量较低。护理心力衰竭患者的主要目标之一是提高他们的生活质量。
本研究旨在调查使用基于智能手机的应用程序对心力衰竭患者生活质量的影响。
2018年6月至10月在一家城市医院进行了这项设有对照组的随机对照临床试验。在本研究中，将120名入住心脏监护病房的心力衰竭患者随机分为对照组和干预组。除常规护理外，干预组患者接收一款基于智能手机的应用程序，并每天使用3个月。两组在进入研究前和进入研究后3个月均完成明尼苏达心力衰竭生活问卷。使用SPSS软件V.16对数据进行分析。
干预后，两组在生活质量及其维度的平均得分上显示出统计学上的显著差异，从而表明干预组的生活质量更好（P<.001）。干预对生活质量的效应大小为1.85（95%CI 1.41-2.3）。此外，两组在生活质量得分及其维度的变化上也显示出统计学上的显著差异（P<.001）。
使用基于智能手机的应用程序可以提高心力衰竭患者的生活质量。我们的研究结果建议使用数字应用程序来改善心力衰竭患者的管理。
