Brazilian registries  have shown that there is a gap between evidence-based therapies and the real treatment provided to patients with myocardial infarction. A chest pain protocol was implemented in a private hospital group in 2012 aiming at standardized optimal care for these patients.
To evaluate the hypothesis of improving the use of reperfusion therapy and benefit in clinical outcomes in patients with STEMI after 2 years of implementation of the protocol in a large chest pain network.
In 2012, physicians and nurses from 22 emergencies were trained to comply with a chest pain protocol and were provided access to telemedicine with a reference cardiologist available 24 hours a day, 7 days a week, for clinical discussion. All cases of ST segment elevation myocardial infarction (STEMI) were transferred to a reference hospital and the use of fibrinolytics before transfer (pharmacoinvasive strategy) was recommended. Data of STEMI patients transferred in 2011 (before protocol and telemedicine) were compared with the patients treated in 2013/14 (after implementation). A maximum limit of significance of 5% was defined for the chance of type I error (p < 0.05 was considered statistically significant).

Two years after implementation of a chest pain protocol in a private emergency network, there was significant increase in the use of reperfusion therapy probably explained by a more frequent use of telemedicine in the group treated with reperfusion therapy.
