DESIGN: Controlled clinical trial with single randomization, unmasked, open and multicentric.

CENTERS: University Hospital of A Coruña and University Hospital of Ferrol CONDITION TO STUDY: Acute Coronary Syndrome (ACS). INTERVENTION:monitored outhospital not inhospital supervised. MAIN OBJECTIVE: To determine the incidence of major adverse events (total mortality, new ACS, coronary revascularization, all-cause hospitalization) during the one-year period after hospitalization for ACS.

The SPRING study aims to learn whether a remote, nurse-guided secondary prevention program reduces adverse events in patients who suffer an infarction during the subsequent one-year period. The SPRING study focuses not only on adverse events but also on the patients' state of life in terms of diet, physical exercise, emotional state, tobacco use, and adherence to medical treatment. Nursing is a profession in charge of preserving the health of patients, which is why the remote secondary cardiovascular prevention program of this study is coordinated by a nurse.

Inclusion Criteria:

• All patients who have suffered an ACS in the health area of A Coruña or Ferrol from the beginning of the study inclusion period until reaching the fixed sample size.
• Ages between 18 and 75 years.
• Patients with ability to read and understand the participation sheet in the study.
• Patients signing informed consent to participate in the study.
• Patients living in the health care area of HUAC or HUF.

Exclusion Criteria:

• Patients who are dependent for the Basic Activities of Daily Living (BADL) or who suffer from severe cognitive impairment (which makes reliable anamnesis impossible).
• Patients with a Left Ventricular Ejection Fraction (LVEF) less than or equal to 35%.
• Patients with a NYHA III / IV score and / or the Canadian Cardiovascular Association (CCS) scale of IV.

The data of the participants can not be used by other researchers
