Isquemia peri-operatoria silente de miocardio y resultados adversos a largo plazo en pacientes con cirugía no cardiaca
El monitoreo de la isquemia perioperatoria silente de miocardio no brindaría ayuda para la predicción de complicaciones cardiovasculares a largo plazo.

Los investigadores hallaron 34 eventos adversos durante el período que duró el estudio, 24 ocurrieron dentro de los 6 meses y los 10 restantes tuvieron lugar entre los 6 y los 12 meses posteriores a la operación. La isquemia silenciosa de miocardio fue asociada con resultados adversos en los primeros 6 meses [OR4.44 (95% CI, 1.77-11.13)] y durante el periodo completo del estudio [OR 2.81 (1.26-6.07)]. Asimismo, otros factores de riesgos encontrados fueron: cirugía vascular [OR17.09(2.67-351.44)], historia de angina [OR6.29(2.21-17.62)], tratamiento concurrente con bloqueadores de la entrada de calcio [OR2.68(1.03-6.93)] y consumo de tabaco [OR4.93(2.00-12.02)]. Sin embargo, ninguno de ellos fue un pronosticador de uso para las consecuencias a largo plazo (entre 6 y 12 meses postcirugía).
Los investigadores concluyeron que el monitoreo de isquemia perioperatoria silente de miocardio no brinda ayuda para la predicción de complicaciones cardiovasculares a largo plazo.
