Development of regionalized STEMI care networks in Brazil.

We read with great interest the article by Caluza et al. “ST-Elevation myocardial infarction network: systematization in 205 cases reduced clinical events in the public health care system”. The creation of regionalized STEMI care networks, integrating different levels of complexity, reduces time interval until treatment, including door-to-needle and door-to-balloon time and increases the proportion of primary reperfusion, currently constituting a class I recommendation, level of evidence: B1,2. In fact, the implementation of STEMI care networks and systems has been a trend for more than a decade3, and, in 2011, through the “Line of care of acute myocardial infarction in the emergency care network”, the implementation of STEMI care networks in metropolitan regions became a recommendation of the Ministry of Health of Brazil4.
