Resumen

La expansión y el descubrimiento de nuevas posibilidades de diagnóstico para el uso de muchos biomarcadores de enfermedades cardiovasculares (ECV), incluidas las isoformas de troponina cardioespecíficas (cTnI, cTnT), se debe a la mejora de los métodos de laboratorio para su determinación. A lo largo de una prolongada historia de la creación y mejora de métodos inmunoquímicos para la determinación de cTnI y cTnT, se observaron cambios significativos en el concepto de biología y su valor diagnóstico como biomarcadores de ECV. Los métodos obsoletos de detección de cTnI, cTnT, llamados de sensibilidad baja y moderada, se distinguieron por una sensibilidad relativamente baja, lo que llevó a la confirmación tardía del diagnóstico de infarto agudo de miocardio (IAM) y, por lo tanto, dichos métodos fueron reemplazados gradualmente por nuevos métodos de alta y moderada sensibilidad, como definiciones de métodos ultrasensibles (hs-cTnI, hs-cTnT). Con la introducción de hs-cTnI y hs-cTnT en la práctica clínica, la posibilidad de diagnóstico precoz y exclusión del IAM mediante la evaluación de la cinética de la concentración de hs-cTnI y hs-cTnT en las primeras horas (0-1 hora, 0-2 horas, 0-3 horas) desde el momento en que el paciente ingresa a urgencias. Además, algunas de nuestras ideas sobre la biología de las troponinas cardíacas han cambiado, y han surgido nuevas oportunidades prometedoras para su uso en medicina. En este artículo se discuten las características analíticas clave de los métodos de detección de hs-cTnI y hs-cTnT en comparación con métodos moderadamente sensibles, e informa sobre nuevos datos biológicos y algunas nuevas posibilidades de diagnóstico para el uso de hs-cTnI y hs-cTnT en la práctica clínica moderna.
