Bivalirudin versus heparin in ST and non-ST-segment elevation myocardial infarction
Systematic review published in Cardiovasc Revasc Med (2024)
Abstract
BACKGROUND: The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years. METHODS: Analysis of primary and secondary endpoints at two years of follow-up was prespecified in the study protocol. We report the study results for the extended follow-up time here. RESULTS: In total, 6006 patients were enrolled, 3005 with ST-segment elevation MI (STEMI) and 3001 with Non-STEMI (NSTEMI), representing 70 % of all eligible patients with these diagnoses during the study. The primary endpoint occurred in 14.0 % (421 of 3004) in the bivalirudin group compared with 14.3 % (429 of 3002) in the heparin group (hazard ratio [HR] 0.97; 95 % confidence interval [CI], 0.85-1.11; P = 0.70) at one year and in 16.7 % (503 of 3004) compared with 17.1 % (514 of 3002), (HR 0.97; 95 % CI, 0.96-1.10; P = 0.66) at two years. The results were consistent in patients with STEMI and NSTEMI and across major subgroups. CONCLUSIONS: Until the two-year follow-up, there were no differences in endpoints between patients with MI undergoing PCI and allocated to bivalirudin compared with those allocated to heparin.

Zusammenfassung
Bivalirudin (leech-derived) versus heparin systematic review across STEMI and NSTEMI populations.
Warum dies für die Hirudotherapie relevant ist
This registry-based randomized controlled trial (VALIDATE-SWEDEHEART) compared bivalirudin versus heparin in 6,006 patients undergoing percutaneous coronary intervention for myocardial infarction, reporting outcomes at two years of follow-up. The study found no significant differences between the bivalirudin and heparin groups in the composite endpoint of death, myocardial infarction, or major bleeding at two years, with consistent results across STEMI and NSTEMI subgroups. The abstract does not describe bivalirudin's origin, structure, or any relationship to hirudin, leeches, or the leech secretome. The abstract makes no mention of leeches or hirudotherapy, so this study has no defensible relevance to ASH's domain.
