The m-Health programmes reported positive effects on adherence to medication .
Conclusion Evidence exists that supports the use of e-Health interventions for improving secondary prevention of CAD .
However , a comparison across studies highlighted a wide variability of components and outcomes within the different modes of delivery .
Background Electronic health ( e-Health ) interventions are emerging as an effective alternative model for improving secondary prevention of coronary artery disease ( CAD ) .
The aim of this study was to describe the effectiveness of different modes of delivery and components in e-Health secondary prevention programmes on adherence to treatment , modifiable CAD risk factors and psychosocial outcomes for patients with CAD .
A mobile phone intervention increases physical activity in people with cardiovascular disease: Results from the HEART randomized controlled trial
Aim To determine the effectiveness and cost-effectiveness of a mobile phone intervention to improve exercise capacity and physical activity behaviour in people with ischaemic heart disease ( IHD ) . Methods and results In this single-blind , parallel , two-arm , r and omized controlled trial adults ( n = 171 ) with IHD were r and omized to receive a mobile phone delivered intervention  ( HEART ; n = 85 ) plus usual care , or usual care alone ( n = 86 ) . Adult participants aged 18 years or more , with a diagnosis of IHD , were clinical ly stable as out patients , able to perform exercise , able to underst and and write English , and had access to the Internet . The HEART ( Heart Exercise And Remote Technologies ) intervention involved a personalized , automated package of text messages and a secure website with video messages aim ed at increasing exercise behaviour , delivered over 24 weeks . All participants were able to access usual community-based cardiac rehabilitation , which involves encouragement of physical activity and an offer to join a local cardiac support club . All outcomes were assessed at baseline and 24 weeks and included peak oxygen uptake ( PVO2 ; primary outcome ) , self-reported physical activity , health-related quality of life , self-efficacy and motivation ( secondary outcomes ) . Results showed no differences in PVO2 between the two groups ( difference −0.21 ml kg−1 min−1 , 95 % CI : −1.1 , 0.7 ; p = 0.65 ) at 24 weeks . However significant treatment effects were observed for selected secondary outcomes , including leisure time physical activity ( difference 110.2 min/week , 95 % CI : −0.8 , 221.3 ; p = 0.05 ) and walking ( difference 151.4 min/week , 95 % CI : 27.6 , 275.2 ; p = 0.02 ) . There were also significant improvements in self-efficacy to be active ( difference 6.2 % , 95 % CI : 0.2 , 12.2 ; p = 0.04 ) and the general health domain of the SF36 ( difference 2.1 , 95 % CI : 0.1 , 4.1 ; p = 0.03 ) at 24 weeks . The HEART programme was considered likely to be cost-effective for leisure time activity and walking . Conclusions A mobile phone intervention was not effective at increasing exercise capacity over and above usual care . The intervention was effective and probably cost-effective for increasing physical activity and may have the potential to augment existing cardiac rehabilitation services
