There was no significant between group difference in six-minute walk test distance .
Conclusions Our meta- analysis showed WPAM with exercise prescription or advice are superior to no device in improving CRF in the maintenance phase of CR and no cardiac adverse events were reported with WPAM use .
Our qualitative analysis showed evidence in favour of WPAM with exercise prescription or advice for both CRF and step count .
WPAM with exercise prescription or advice did not change sedentary time .
Background Physical activity ( PA ) is a component of cardiac rehabilitation ( CR ) .
However , life-long engagement in PA is required to maintain benefits gained .
Wearable PA monitoring devices ( WPAM ) are thought to increase PA .
There appear to be no review s which investigate the effect of WPAM in cardiac population s. We firstly aim ed to systematic ally review r and omised controlled trials within the cardiac population that investigated the effect WPAM had through the maintenance phase of CR .
We specifically examined the effect on cardiorespiratory fitness ( CRF ) , amount and intensity of daily PA , and sedentary time .
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
