Cardiovascular diseases continue to be the first cause of death in Brazil - responsible for almost 32% of all deaths. In addition, they are the third major cause of admission in the country. Among them, acute myocardial infarction is still one of the major causes of morbidity and mortality. Despite of the last decade's therapeutic advances, acute myocardial infarction still shows remarkable rates of mortality, and great part of the patients do not receive the adequate treatment. The opening of the Coronary Care Units and the introduction of reperfusion treatment with fibrinolytics or primary angioplasty were fundamental to reduce mortality and complications related to myocardial infarction. Important beneficial effects to the current treatment include less ventricular dysfunction and better control of ventricular arrhythmias. The need of early reperfusion is crucial for the good prognosis after a myocardial infarction. The objective of this review is to emphasize the modern basic concepts of the pathophysiology, diagnosis and treatment of acute myocardial infarction, according to national and international guidelines.
