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 .
Role of telecardiology in the assessment of angina in patients with recent acute coronary syndrome
We compared two models of assistance ( telecardiology versus usual care ) for patients discharged after acute coronary syndrome ( ACS ) , in the assessment of angina .  Two hundred patients were r and omized into two groups at discharge for ACS : Group A to telecardiology and Group B to usual care .  Early hospital readmission ( in the first month ) occurred in 16 patients ( seven in Group A and nine in Group B ) . Six of Group A were readmitted for a cardiac cause ( non-cardiac in one ) . Angina was the only cardiac cause . Five of the Group B patients were readmitted for a cardiac cause ( non-cardiac in four ) . The results of the present study emphasize that patients with ACS suffer from a definite rate of cardiac symptoms within the first month ( 63 % ) . Angina occurs more frequently within the first two weeks ( 68 % of cases ) . Telecardiology slightly reduces hospital readmissions  ( telecardiology 44 % versus usual care 56 % ) , but better identifies true angina
