Objective To examine the willingness of patients with cardiovascular disease to use a cardiovascular exercise management application(App)and its impact on cardiovascular adverse events.Methods The research objects consisted of 202 patients with cardiovascular disease.A self-designed questionnaire was used to investigate patients'exercise needs,health management status,and factors affecting their choice of cardiovascular exercise management App.Based on the survey results,140 patients who used the cardiovascular exercise management App were assigned to the exercise group,while 62 patients who did not use the App were assigned to the control group.The incidence of cardiovascular adverse events within one year was compared between the two groups.Results In the survey,74.26%of respondents believed that they required reasonable exercise,while 89.11%believed that they needed to track their exercise.Additionally,84.16%of respondents reported using smartphones in their daily lives,and 81.68%found it convenient to use a cardiovascular exercise management App.Furthermore,74.26%of patients paid attention to their own health,and 53.96%believed that health could be managed.The majority of patients,74.75%,also paid attention to and addressed their physical examination reports,and 62.87%currently used online medical Apps.The study found that the main concerns for patients with cardiovascular disease using exercise management Apps were fear of charging during use(79.21%),fear of personal information disclosure(76.24%),and difficulty in choosing similar Apps(59.41%).Additionally,after a year of follow-up,the incidence of adverse cardiovascular events was significantly lower in the exercise group(4.28%)compared to the control group(14.52%)(χ2 = 6.542,P = 0.011).Conclusions Cardiovascular exercise management Apps have the potential to reduce the incidence of adverse cardiovascular events.However,the fear of charging for use and disclosing personal information has limited the willingness of cardiovascular disease patients to use them.
