Thorombolytic therapy with rescue percutaneous coronary intervention versus primary percutaneous coronary intervention in patients with acute myocardial infarction: a multicenter randomized clinical trial.

Background: Although thrombolytic therapy with rescue percutaneous coronary intervention (PCI) is a common treatment strategy for ST-segment elevation acute myocardial infarction (STEMI), scant data are available on its efficacy relative to primary PCI, and comparison was therefore the aim of this study.

Methods: This multicenter, open-label, randomized, parallel trial was conducted in 12 hospitals on patients (age < or = 70 years) with STEMI who presented within 12 hours of symptom onset (mean interval > 3 hours). Patients were randomized to three groups: primary PCI group (n = 101); recombinant staphylokinase (r-Sak) group (n = 104); and recombinant tissue-type plasminogen activator (rt-PA) group (n = 106).
