The safety and effectiveness of bivalirudin in female patients with acute myocardial infarction undergoing primary angioplasty: A subgroup analysis of the BRIGHT trial
Randomized controlled trial published in Catheter Cardiovasc Interv (2016)
Abstract
BACKGROUND: Being female is an independent predictor of adverse events during percutaneous coronary interventions (PCI). OBJECTIVE: To evaluate the safety and efficiency of bivalirudin during emergency PCI in female patients with acute myocardial infarction (AMI). METHODS: The present study was a subgroup analysis of the randomized Bivalirudin in Acute Myocardial Infarction vs. Heparin and GPI plus Heparin (BRIGHT) trial. A total of 392 female patients enrolled in the BRIGHT trial were assigned to receive bivalirudin with post-procedure dose infusion (n = 127) or heparin with or without tirofiban (n = 265). The primary efficiency endpoint was 30-day net adverse clinical events (NACEs). The secondary efficiency endpoints were 30-day major cardiac and cerebral events (MACCEs) and bleeding events defined according to Bleeding Academic Research Consortium (BARC) definitions. RESULTS: For female patients, bivalirudin treatment was associated with significantly lower incidences of 30-day NACEs (6.3% vs. 21.5%, P < 0.001), any bleeding (2.4% vs. 12.8%, P = 0.001) and BARC 2-5 type bleeding (1.6% vs. 7.2%, P = 0.021) compared with the control regimen. The incidence of MACCEs (3.4% vs. 9.4%, P = 0.055) and stent thrombosis (0% vs. 1.1%, P = 0.229) were comparable between the two groups. Multivariate analysis showed that bivalirudin (OR: 0.245, 95% CI: 0.113-0.532, P < 0.001), transradial access (OR: 0.119, 95% CI: 0.067-0.211, P < 0.001), and statin (OR: 0.254, 95% CI: 0.08-0.807, P = 0.02) were independent protective factors for 30-day NACEs in female patients. CONCLUSIONS: The use of bivalirudin during emergency PCI for AMI in female patients significantly reduced the bleeding risk with anticoagulation effects compared with heparin with or without tirofiban.

Resumen
BRIGHT trial subgroup of 392 female patients showed bivalirudin reduced 30-day NACE 6.3% vs 21.5% with comparable MACCE rates.
Por qué esto importa para la hirudoterapia
Este análisis de subgrupo preespecificado del ensayo aleatorizado BRIGHT evaluó bivalirudin frente a heparin (con o sin tirofiban) en 392 pacientes femeninas sometidas a PCI primaria por infarto agudo de miocardio, encontrando que bivalirudin se asoció con eventos clínicos adversos netos a 30 días significativamente menores (6.3% vs. 21.5%) y una menor incidencia de cualquier tipo de sangrado (2.4% vs. 12.8%), con tasas comparables de eventos cardiacos/cerebrales mayores y trombosis del stent. Esta es una de las entradas de cardiología más directamente relevantes para ASH debido a que bivalirudin es un DTI bivalente diseñado a partir de hirudin, el péptido anticoagulante de la sanguijuela medicinal —un ejemplo concreto de cómo el secretoma de la sanguijuela madura hasta convertirse en un fármaco aprobado y probado en ensayos. Advertencia honesta: se trata de un análisis de subgrupo (secundario) de un único ensayo, por lo que el beneficio de sangrado específico en mujeres respalda la hipótesis pero no es definitivo, y el estudio se refiere a un fármaco derivado de hirudin, no a la terapia con sanguijuelas practicada clínicamente.
