RESUMEN
Propósito. La albúmina modificada por isquemia (AMI) es un nuevo marcador de isquemia que se utiliza especialmente en urgencias. El objetivo de este estudio es mostrar la asociación de la AMI con isquemia inducida por el estrés en la gammagrafía de perfusión miocárdica (MPS) con 99mTc 2-metoxi-nitrato (MIBI). Métodos. En nuestro estudio se incluyeron 56 pacientes (23 mujeres, 33 hombres; 56, 04 ± 8,45 años). A todos los pacientes se les realizó un MPS con MIBI siguiendo un protocolo reposo-estrés de 2 días. Los niveles séricos de AMI se midieron antes y después de la prueba de esfuerzo. Además, a treinta pacientes se les realizó un estudio hemodinámico. Resultados. No se encontró una diferencia estadística significativa entre los niveles de AMI en los grupos de pacientes que tenían isquemia y los que no tenían isquemia. Además, no hubo diferencia estadísticamente significativa entre los niveles de AMI de los pacientes con estenosis en las arterias coronarias y los que no mostraron estenosis. Conclusión. A pesar de que la AMI es un marcador importante de la isquemia, no puede reflejar el estrés inducido por cambios isquémicos en el MPS probablemente a causa de otros procesos isquemicos que se producen durante el estrés(AU)
ABSTRACT
Purpose. Ischemia modified albumin (IMA) is a new marker of ischemia which is used in especially emergency room. Aim of this study is showing the association of IMA with stress induced ischemia on Tc-99m 2-methoxyisobutyl-nitrate (MIBI) myocardial perfusion scintigraphy (MPS). Methods. 56 patients (23 F, 33 M; 56.04±8.45 years old) were included in our study. Stress-rest two days protocol Tc-99m MIBI MPS single photon emission tomography (SPECT) was performed to all patients. IMA levels from the blood samples which were taken before and after the treadmill test were measured. Thirty patients additionally underwent coronary angiography. Results. The difference of IMA levels of ischemia between positive and negative groups was not statistically significant. Also, there was not statistically significant difference between IMA levels of patients who have narrowing in the coronary arteries and not. Conclusion. Although IMA is an important marker of ischemia, probably because of other ischemic process during stress; it cannot reflect stress induced ischemic changes on MPS(AU)
