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 .
The Know & Go! program improves knowledge for patients with coronary heart disease in pilot testing.
OBJECTIVE To determine if patients hospitalized for angioplasty could learn about symptoms , risk factors , and care-seeking behaviors before and after discharge and to assess patient acceptability of the intervention . METHODS Thirty-two women and 32 men were r and omly assigned to groups and completed an intervention pretest . The experimental group viewed the Know & Go ! slide presentation at baseline and 2 and 4 months after discharge . A satisfaction survey was mailed to patients in the experimental group . RESULTS There were no significant differences between groups in clinical or sociodemographic characteristics . The experimental group scored significantly higher on an intervention posttest at study completion ( F = 15.21 ; P < .001 ) . Patients were highly satisfied with the program and computer technology ( range 0 - 12 , M = 9.57 ± 1.83 ) . CONCLUSION The Know & Go ! intervention was safe , effective , and acceptable to patients in pilot testing . Results support refinement and further testing of the intervention for patients diagnosed with coronary heart disease
