Intervention participants were 50% more likely to have a hospital admission, twice as likely to have an ED presentation, and 3 times more likely to be admitted to the hospital for a cardiac-related hospital admission. This contrasts with the studies by Widmer et al [Cardiac rehabilitation is associated with significant reductions in hospitalizations and repeat cardiac events [Those in the intervention group attended the ED more frequently than those in the control group, and the most frequent cause for admission was chest pain (AR-DRG code F74B). Presenting to the ED for chest pain is particularly relevant with advice given in the Vire app and ToDo-CR program to seek medical attention if participants experienced these symptoms. These participants may have become more proactive in self-managing their CHD because of the education provided. Public education campaigns to raise awareness of the signs and symptoms of acute chest pain have been shown to be effective in increasing the rate of ED presentations for early medical intervention [Although the effect size for reduction in sedentary behavior was small in this study, an approximate 20-minute reduction may still be clinically meaningful. In the limited studies available that test the effect of smartphone apps on sedentary behavior [The waist-to-hip ratio (0.03) and BMI (1.64 kg/mA high percentage of the intervention group did not complete a single In line with the feasibility trial preceding this study [Although smartphone apps have the potential to be a cost-effective solution [
