While the results of this systematic review are promising , there is insufficient evidence to draw conclusions on the effectiveness of text message-based interventions for adherence to medications for secondary prevention of CVD .
BACKGROUND Worldwide at least 100 million people are thought to have prevalent cardiovascular disease ( CVD ) .
This population has a five times greater chance of suffering a recurrent cardiovascular event than people without known CVD .
Secondary CVD prevention is defined as action aim ed to reduce the probability of recurrence of such events .
Drug interventions have been shown to be cost-effective in reducing this risk and are recommended in international guidelines .
However , adherence to recommended treatments remains sub-optimal .
In order to influence non-adherence , there is a need to develop scalable and cost-effective behaviour-change interventions .
OBJECTIVES To assess the effects of mobile phone text messaging in patients with established arterial occlusive events on adherence to treatment , fatal and non-fatal cardiovascular events , and adverse effects .
Long-term results after a telephone intervention in chronic heart failure: DIAL (Randomized Trial of Phone Intervention in Chronic Heart Failure) follow-up.
OBJECTIVES The purpose of this study was to assess the rate of death and hospitalization for heart failure ( HF ) 1 and 3 years after a r and omized trial of telephone intervention aim ed to improve education and compliance in stable patients with HF ended . BACKGROUND The long-term effects of HF programs are not well known . METHODS In all , 1,518 patients with HF were r and omized into the DIAL ( R and omized Trial of Phone Intervention in Chronic Heart Failure ) . After completion of the trial , patients were followed up to 3 years to assess major outcomes . Compliance with diet , weight control , and treatment was evaluated . The effect of the intervention on mortality and HF hospitalizations was assessed using relative risk ( RR ) , relative risk reduction , and Cox proportional hazards model for adjusting by potential confounders . RESULTS The rate of death or hospitalization for HF was lower in the intervention group ( 37.2 % vs. 42.6 % , RR : 0.81 , 95 % confidence interval [ CI ] : 0.69 to 0.96 ; p = 0.013 ) 1 and 3 years ( 55.7 % vs. 57.5 % , RR : 0.88 , 95 % CI : 0.77 to 1.00 ; p = 0.05 ) after the intervention ended . This benefit was mainly caused by a reduction in admission for HF ( 28.5 % vs. 35.1 % after 3 years , RR : 0.72 , 95 % CI : 0.60 to 0.87 ; p = 0.0004 ) . Patients who showed improvement in 1 or more of 3 key compliance indicators ( diet , weight control , and medication ) had lower risks of events . CONCLUSIONS The benefit observed during the intervention period persisted and was sustained 1 and 3 years after the intervention ended . This effect may be explained by the impact of the educational intervention on patients ' behavior and habits
