[Angiographic result with the use of adenosine before percutaneous coronary intervention in pharmacoinvasive therapy].

Background: Mexico is the country with the highest mortality from acute myocardial infarction (AMI), which is why guidelines have been established for early reperfusion in which fibrinolysis is the second most accessible method. However, there is a percentage of patients who do not achieve acceptable myocardial perfusion and this is associated with adverse cardiovascular outcomes. Different adenosine schemes have been used as an adjuvant to restore adequate myocardial perfusion.
