Original Uncertainty

Implications for Research The current evidence on the use of the Internet in the secondary prevention of heart disease is still evolving and has shown mixed results. A number of questions have been raised. We particularly need to investigate the long-term effects of web-based interventions used in the secondary prevention of CHD on cardiovascular risk factor profiles and clinical events. There is also a need to determine the intensity and duration of the intervention required to achieve effective secondary prevention of CHD and the effective components of behavioural changes. With regards to the socio-demographic characteristics of the CHD population, future studies should focus interventions on a wide range of participants so that findings are generalisable and can also be tailored to specific populations if differences are found. More rigorous studies comparing the long-term effects of Internet interventions are needed in order to determine long-term effectiveness of Internet interventions for the secondary prevention of CHD. There is also a need to measure outcomes objectively. Physical activity was assessed using self report measures in six out of eight trials. These measures are susceptible to overestimations, which the use of accelerometer technology would reduce. Future trials should also include cost-effectiveness outcomes.
