A pesar de los avances y de la aplicación de criterios más objetivos, las mujeres siguen teniendo menos probabilidades que los varones de ser correctamente diagnosticadas de infarto de miocardio, según publican en "Heart" investigadores del Hull Royal Infirmary (Reino Unido).
Al infradiagnosticarse el infarto en mujeres "estamos perpetuando el mito de que son principalmente los hombres los que experimentan infartos", señalan los autores.
Añaden que las actuales directrices establecen que la elevación de dos enzimas –la troponina cardíaca T y la troponina cardíaca I- es suficiente para diagnosticar un infarto de miocardio. En su estudio, evaluaron 6.172 muestras de troponina cardíaca T de 2.505 varones y de 2.323 mujeres admitidas en su hospital por dolor torácico en el año 2002.
Un total de 1.304 admisiones (713 varones y 591 mujeres) fueron asociadas con niveles elevados de troponina cardíaca T. Sin embargo, sólo el 40% de los casos fueron dados de alta con diagnóstico de infarto de miocardio. El 46% correspondía a varones y sólo el 33% a mujeres.
