Abstract
Chest pain is a very common cause for consultation in hospital emergency departments (HEDs). It is estimated that it represents about 5% to 20% of the total volume of visits per year. As it has a highly varied etiology, it represents a diagnostic challenge. For this reason, verifying alarm signs that are able to identify situations that are life threatening to the patient per se is an initial priority in order to determine whether there is a need for emergency action or not. In HEDs, it is important to have a diagnostic protocol for this type of situation, as it encompasses time-sensitive diseases that not only the patient's quality of life, but also their survival depend on.
