Similarly , there was no clear evidence of effect for cardiovascular risk factors , although again the number of studies reporting these was small .
There was some evidence for beneficial effects on HRQOL , dietary outcomes , and physical activity , although firm conclusions can not yet be made .
The effects on healthcare utilisation and cost-effectiveness are also inconclusive , and trials are yet to measure the impact of  Internet interventions on compliance with medication .
BACKGROUND The Internet could provide a means of delivering secondary prevention programmes to people with coronary heart disease ( CHD ) .
OBJECTIVES To determine the effectiveness of Internet-based interventions targeting lifestyle changes and medicines management for the secondary prevention of CHD .
Designing a theory- and evidence-based tailored eHealth rehabilitation aftercare program in Germany and the Netherlands: study protocol
Background Cardiac rehabilitation programs aim to improve health status and to decrease the risk of further cardiac events .  Persons undergoing rehabilitation often have difficulties transferring the learned health behaviors into their daily routine after returning home and maybe to work . This includes physical activity as well as fruit and vegetable consumption . Computer-based tailored interventions have been shown to be effective in increasing physical activity as well as fruit and vegetable consumption . The aim of this study is , to support people in transferring these two learned behavior changes and their antecedents into their daily life after cardiac rehabilitation . Methods The study will have a r and omized controlled design and will be conducted among German and Dutch people who participated in cardiac rehabilitation . The study will consist of one intervention group which will be compared to a waiting list control group . During the eight week duration of the intervention , participants will be invited to participate in the online after-care program once per week . The intervention encourages participants to define individual health behavior goals as well as action , and coping plans to reach these self-determined goals . The effectiveness of the program will be compared between the intervention condition and the control group in terms of behavior change , antecedents of behavior change ( e.g. , self-efficacy ) , ability to return to work and increased well-being . Further , subgroup-differences will be assessed including differences between the two countries , socioeconomic inequalities and across age groups . Discussion The present study will make a contribution to underst and ing how such an online-based tailored interventions enables study participants to adopt and maintain a healthy lifestyle . Implication s can include how such an online program could enrich cardiac rehabilitation aftercare further . Trial registration NTR 3706 ,
