Coronariografía urgente en los pacientes con parada cardiaca extrahospitalaria sin elevación del segmento ST. Ensayo clínico COUPE / Coronary angiography in patients without ST-segment elevation following out-of-hospital cardiac arrest. COUPE clinical trial

Introducción y objetivos El papel de la coronariografía urgente y angioplastia, si procede, en los pacientes con parada cardiaca extrahospitalaria (PCEH) recuperada que no presentan elevación del segmento ST es controvertido. Nuestro objetivo fue evaluar si la coronariografía urgente y la angioplastia mejoran la supervivencia con buen pronóstico neurológico en esta población. Métodos En este ensayo clínico multicéntrico, aleatorizado, abierto, incluimos 69 pacientes supervivientes a una PCEH sin elevación del ST y se aleatorizaron a recibir una coronariografía urgente (CU) o diferida (CD). El objetivo primario de eficacia fue el combinado de supervivencia hospitalaria libre de dependencia. El objetivo de seguridad fue un compuesto de eventos cardiacos mayores, incluyendo muerte, reinfarto, sangrado y arritmias ventriculares. Resultados Se incluyó a 66 pacientes en el análisis primario (95,7%). La supervivencia hospitalaria fue 62,5% en el grupo CU y 58,8% en el grupo CD (HR = 0,96; IC95%, 0,45-2,09; p=0,93). La supervivencia hospitalaria con buen pronóstico neurológico fue 59,4% en el grupo CU y 52,9% en el grupo CD (HR = 1,29; IC95%, 0,60-2,73; p=0,4986). No se encontraron diferencias en los objetivos secundarios, salvo por la incidencia de fracaso renal agudo, que fue más frecuente en el grupo CU (15,6 frente a 0%, p=0,002) y de infecciones, más prevalentes en el grupo CD (46,9 frente a 73,5%, p=0,003). Conclusiones En este estudio aleatorizado de pacientes con una PCEH sin elevación del ST, una CU no fue beneficiosa en términos de supervivencia con buen pronóstico neurológico comparada con una CD (AU)

Introduction and objectives The role of emergency coronary angiography (CAG) and percutaneous coronary intervention (PCI) following out-of-hospital cardiac arrest (OHCA) in patients without ST-segment elevation myocardial infarction (STEMI) remains unclear. We aimed to assess whether emergency CAG and PCI would improve survival with good neurological outcome in this population. Methods In this multicenter, randomized, open-label, investigator-initiated clinical trial, we randomly assigned 69 survivors of OHCA without STEMI to undergo immediate CAG or deferred CAG. The primary efficacy endpoint was a composite of in-hospital survival free of severe dependence. The safety endpoint was a composite of major adverse cardiac events including death, reinfarction, bleeding, and ventricular arrhythmias. Results A total of 66 patients were included in the primary analysis (95.7%). In-hospital survival was 62.5% in the immediate CAG group and 58.8% in the delayed CAG group (HR, 0.96; 95%CI, 0.45-2.09; P=.93). In-hospital survival free of severe dependence was 59.4% in the immediate CAG group and 52.9% in the delayed CAG group (HR, 1.29; 95%CI, 0.60-2.73; P=.4986). No differences were found in the secondary endpoints except for the incidence of acute kidney failure, which was more frequent in the immediate CAG group (15.6% vs 0%, P=.002) and infections, which were higher in the delayed CAG group (46.9% vs 73.5%, P=.003). Conclusions In this underpowered randomized trial involving patients resuscitated after OHCA without STEMI, immediate CAG provided no benefit in terms of survival without neurological impairment compared with delayed CAG (AU)
