Mortality after myocardial infarction.  Thrombolytic therapy or angioplasty. During the recent decades, acute myocardial infarction short-term mortality has decreased to one digit levels, in the United States. Data from Chilean registries give figures around 11% for thrombolysis, and between 5 to 6 % for angioplasty. The decrease in mortality is related to the implementation of the AUGE program at a national level, initiative than gives to the public the opportunity to receive at least thrombolytic therapy as well as a standarized and rapid diagnosis and treatment for this condition. There is a lack of Outcome Research studies in our country,  that would help to take public health decisions such as the use of fibrin-specific agents for early presentation and high risk cases, and a rational system for having better access to primary angioplasty.
