Myocardial infarction continues to be one of the leading causes of morbidity and mortality nowadays. Mechanical reperfusion by primary angioplasty is the best possible treatment, but increased symptom-to-balloon and door-to-balloon times have been associated with higher mortality rates in ST-elevation myocardial infarction (STEMI) . Delays in the performance of primary angioplasty may be caused by the patient's delay in requesting medical care, but also by the health system's delay in responding to it. Having said so, it should be an objective of the healthcare systems to facilitate the population's access to primary angioplasty in the shortest time possible, and that was the reason why the STEMI networks were developed. The goal of these networks is not only to provide primary angioplasty in a timely manner, but also to raise awareness and educate the public so that the population can better recognize the symptoms of a myocardial infarction and, thus, reduce the time it takes to seek medical care by a call to the EMS that will activate the Cath Lab immediately.
