The main objective of cardiovascular disease prevention is to reduce morbidity and mortality by promoting a healthy lifestyle, reducing risk factors, and improving adherence to medications. Secondary prevention after an acute coronary syndrome has proved to be effective in reducing new cardiovascular events, but its limited use in everyday clinical practice suggests that there is considerable room for improvement. The short-term results of evidence-based studies of nurse-coordinated secondary prevention programs have been positive, but there is a lack of long-term outcome data. The Alliance for the Secondary Prevention of Cardiovascular Disease in the Emilia-Romagna region (ALLEPRE) is a multicenter, randomized, controlled trial designed to compare the effects of a structured nurse-coordinated intensive intervention on long-term outcomes and risk profiles after an acute coronary syndrome with those of the standard of care. All of the patients randomized to the intervention group take part in 9 one-to-one sessions with an experienced nurse from the participating centers with the aim at promoting healthy lifestyles, reducing risk factors, and increasing adherence to medication over a mean period of 5 years. The primary clinical end point is the reduction in the risk of the 5-year occurrence of major adverse events (a composite of cardiovascular mortality, nonfatal reinfarction, and nonfatal stroke). The primary surrogate end point is the achievement of prespecified targets relating to classical risk factors, lifestyle modifications, and adherence to pharmacological therapy after 2 years of follow-up. Coronary heart disease is a chronic degenerative disease, and patients who recover from an acute coronary syndrome (ACS) are at high risk of developing recurrent events.1 Although secondary prevention measures have proved to be effective and are strongly recommended by all of the international guidelines,2., 3. the 4 EUROASPIRE surveys4., 5., 6., 7., 8. showed that there was still a high prevalence of conventional risk factors, that secondary prevention measures were inadequately implemented, and that their main goals were often not reached. In addition, there were considerable discrepancy in secondary prevention practices between centers and countries, and a widespread underuse of cardiac prevention and rehabilitation programs despite their demonstrated effectiveness in reducing cardiovascular risk over time.9., 10. Over the last 10 years, nurses have been increasingly involved in successful cardiovascular risk management,11., 12., 13. but although this has improved levels of cardiovascular risk, no clear reduction in hard end points such as major cardiovascular adverse events and mortality has been demonstrated.10 The aim of the ALLEPRE trial is to evaluate the benefit of a homogeneous, structured, secondary prevention intervention program, fully coordinated by nurses from in- and outpatient clinics, in terms of cardiovascular risk profiles and major clinical events in ACS patients living in the large Emilia-Romagna region of Italy.
