Los mayores de 75 años, los que no presentan dolor torácico y los que tienen historia de diabetes, insuficiencia cardíaca, infarto de miocardio y han sido sometidos a bypass son los que tienen menos probabilidades de recibir terapia de reperfusión (trombolíticos o angioplastia), según los datos del estudio.
La investigación incluyó a más de 9.000 pacientes de 14 países. Globalmente, unos 1.700 llegaron al hospital dentro de los primeras 12 horas tras los síntomas del infarto.
El uso de terapia trombolítica fue más frecuente en Australia, Nueva Zelanda y Canadá (67% de los pacientes) y menos en Estados Unidos (31%). Se practicó angioplastia en el 18% de los pacientes de Estados Unidos, pero sólo en el 1% de los de Australia, Nueva Zelanda y Canadá. Estados Unidos fue el país donde más habitualmente se combinan las dos técnicas (19% de los pacientes).
Los resultados muestran que el 30% de los infartados no recibe ningún tratamiento de reperfusión, pese a ser candidatos a ello, aunque la explicación no está nada clara.
