Arrhythmic sudden cardiac death (SCD) represents a major worldwide public health problem accounting for\n15-20% of deaths. Risk stratification to identify patients at risk of SCD is crucial in order to implement preventive\nmeasures in the general population. Several biomarkers have been tested exploring different pathophysiological\nmechanisms of cardiac conditions. Conflicting results have been described limiting so far their use in clinical\npractice. The use of new biomarkers such as microRNAs and sex hormones and the emerging role of genetic on\nrisk prediction of SCD is a current research topic showing promising results.\nThis review outlines the role of plasma biomarkers to predict ventricular arrhythmias and SCD in non coronary\nartery disease with a special focus on their relationship with the genetic biomarkers.
