Valor pronóstico de la prueba de esfuerzo en la angina inestable

Abstract

AntecedentesEl desarrollo de nuevas estrategias terapéuticas ha determinado una mejoría sustancial en la historia natural de la angina inestable . Si bien esta evolución favorable ha permitido evaluar a los pacientes que se vuelven asintomáticos con métodos no invasivos, existen escasos estudios que evalúen en ellos el valor pronóstico y la factibilidad de la prueba de esfuerzo. Material y métodoSe determinó la seguridad y el valor pronóstico de la prueba de esfuerzo en 104 pacientes con angina inestable que respondieron al tratamiento médico y fueron seguidos por 4 meses . Resultados Doce pruebas fueron negativas, 31 positivas y 61 insuficientes . Se observó una evolución favorable en todos los pacientes con pruebas negativas, en el 85% de los pacientes con pruebas insuficientes y solamente en el 55% de los pacientes con pruebas positivas (p < 0,005) . La sensibilidad, especificidad y el valor predictivo positivo y negativo de la prueba de esfuerzo para una evolución desfavorable fueron 61%, 45% y 88% respectivamente. En los pacientes con pruebas positivas, el doble producto y la carga al umbral isquémico fueron significativamente mas bajos en aquellos con pronóstico desfavorable : 14.794 ±2 .942 versus 19.718±7.533 y 246,6±129 kgm versus 340 ± 132 kgm, respectivamente (p < 0,05) . ConclusionesLa prueba de esfuerzo luego de la estabilización con tratamiento médico de los pacientes con angina inestable es un procedimiento seguro y útil que permite una estratificación simple del riesgo para determinar su evolución clínica luego del alta
