1-year outcomes of single bolus r-SAK before primary PCI for STEMI: The follow-up of OPTIMA-5.

ABSTRACT: The OPTIMA-5 study demonstrated that a single bolus of half-dose recombinant staphylokinase (r-SAK) before primary percutaneous coronary intervention (PCI) significantly improved the patency of infarct related artery in patients with ST-elevation myocardial infarction (STEMI) expected to undergo PCI within 120 minutes. This study aimed to investigate the 1-year clinical outcome and the effect of the r-SAK antibody on a second r-SAK thrombolysis in OPTIMA-5 patients. The clinical outcome was major adverse cardiovascular events (MACE) within 360 days. Patients' r-SAK antibodies were determined on days 90 ± 7, 180 ± 7, and 360 ± 14 after thrombolysis, and in-vitro r-SAK antibody neutralization experiments were performed to explore an optimal interval for a second r-SAK thrombolysis.
