Device and method for assessing a mortality risk of a cardiac patient based on at least one vital sign or biosignal of said patient The invention relates to a device and method for assessing a mortality risk of a cardiac patient based on at least one vital sign or biosignal of said patient. In order to improve the quality of risk stratification for cardiac patients as compared to conventional mortality risk assessment concepts, the invention provides a device for assessing a mortality risk of a cardiac patient based on at least one vital sign or biosignal of said patient, said device comprising a data provision unit being configured to provide at least one data function of at least one vital sign or biosignal of said patient, a data processing unit being configured to process data of said at least one data function for assessing a mortality risk of said patient by performing the following actions: selecting at least one data sequence from said at least one data function according to a predetermined routine computing a specific behavior of at least one parameter of said at least one data function based on said at least one selected data sequence and assessing a mortality risk of said patient based on said computed behavior. A corresponding method and computer readable medium, which, when loaded, performs steps of said method, are also disclosed.Linvention concerne un dispositif et un procédé pour évaluer un risque de mortalité dun patient cardiaque sur base dau moins un signe vital ou biosignal dudit patient.
