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 .

OBJECTIVES To determine the effectiveness of Internet-based interventions targeting lifestyle changes and medicines management for the secondary prevention of CHD .
Randomized trial of a home recovery intervention following coronary artery bypass surgery.
For this study a r and omized clinical trial was design ed to test the effects of an early home recovery information intervention on physical functioning , psychological distress , and symptom frequency 1 month following coronary artery bypass graft surgery ( CABG ) . Recovery outcomes were compared between two groups : those receiving an audiotape of information on expected physical sensations and their management ( Cardiac Home Information Program [ CHIP ] ) in addition to the usual care , and those receiving the usual cardiac discharge information protocol .  A nonprobability sample of 180 patients ( 84 women and 96 men ; mean age = 62 years ) was equally distributed between the two study groups . When controlling for age , comorbidity , and cardiac functional status , the results showed positive effects on physical functioning in women and psychological distress , vigor and fatigue in men . Consistent with other studies , women had worse physical functioning and more symptom frequency than men . These findings indicate that the CHIP intervention is an effective method to prepare CABG patients for home recovery
