ABSTRACT

El uso de biomarcadores que muestran una asociación con el desarrollo de enfermedad cardiovascular necesita una valoración cuidadosa de la calidad de la evidencia que establece su relación. Aunque los estudios observacionales han sido fundamentales para establecer la importancia de los factores de riesgo tradicionales, únicamente podemos hacer escrutinio e intervenir sobre biomarcadores cuando existe evidencia benéfica de estudios aleatorios clínicos controlados bien diseñados.


The use of biomarkers that show an association with the development of cardiovascular disease needs a careful evaluation in regard to the quality of evidence that establishes their relationship. Although observational studies have been paramount to establish the importance of the traditional risk factors, we can only screen and intervene on biomarkers when there is demonstrated benefit in well-designed randomized clinical trials.
