Primary angioplasty is superior to on-site fibrinolysis in acute myocardial infarction if transfer to the treatment center takes two hours or less.
Does primary angioplasty (including interhospital transfer) reduce the composite of death, reinfarction, or disabling stroke in patients with acute ST-segment elevation myocardial infarction compared to on-site fibrinolysis?
A strategy for reperfusion involving the transfer of patients to an invasive-treatment center for primary angioplasty is superior to on-site fibrinolysis, provided that the transfer takes two hours or less.
Andersen et al. (2003) studied this question. Primary angioplasty is superior to on-site fibrinolysis in acute myocardial infarction if transfer to the treatment center takes two hours or less.
