Treatment adherence is a key element for (i) improving prognosis in cardiovascular and/or high-risk patients, (ii) reducing the burden of morbidity and mortality associated with cardiovascular disease at a population level, and (iii) decreasing costs due to rehospitalizations.Promotion of adherence should embrace all pharmacological and non-pharmacological interventions in cardiovascular prevention, including lifestyle and behavioral changes. In this perspective, cardiac prevention and rehabilitation programs are the most appropriate and cost-effective setting for delivering structured and multi-component interventions on patient's adherence. In this expert opinion document authored by the Italian Association for Cardiovascular Prevention and Rehabilitation, a modern reappraisal of the adherence issue is provided, together with simple, practical, and feasible suggestions to achieve this goal in the real life as well.
