Key result
Post-mortem proteomics identifies promising diagnostic biomarkers when standard autopsy fails to clarify sudden cardiac death etiology.
Why the study?
Despite routine post-mortem investigations, defining the triggering cause of sudden cardiac death remains complicated for forensic pathologists.
Does proteome analysis improve the identification of causes of sudden cardiac death in forensic post-mortem settings?
Does proteome analysis improve the identification of causes of sudden cardiac death in forensic post-mortem settings?
Proteomic analysis of post-mortem samples holds promise for diagnosing the cause of unexplained sudden cardiac deaths in forensic settings, but widespread implementation requires further standardization.

May aid forensic SCD etiology determination when autopsy inconclusive; leaves open standardization and validation before routine adoption.
Sudden cardiac death (SCD) represents a global emergency, with a high number of cases affecting all age groups every year. The prevention of these fatal events requires an accurate knowledge of etiology and pathogenesis, which can vary. Autopsy is an indispensable tool in cases of SCD for diagnostic purposes, as well as for judicial and preventive purposes for family members. Despite the completion of all routine post-mortem investigations, it is often complicated for the forensic pathologist to define the triggering cause of these events. The study of the proteome is proving to be extremely promising in the field of human cardiovascular disease. This paper aims to offer a literature review on the study of the proteome in post-mortem cadaveric biological samples obtained from SCD cases. The aim of this work is to outline the state of the art of the scientific advances that protein analysis can offer in the diagnosis of SCD and the limits that various studies have traced up to now. In conclusion, the work defines the future perspectives of this field in SCD, suggesting strategies to overcome the reported limits and improve the diagnostics of these events.

Sacco et al. (2023) conducted a review in Sudden Cardiac Death (n=28). Proteome analysis was evaluated. Proteomic analysis of post-mortem biological samples offers promising diagnostic biomarkers for identifying the etiology of sudden cardiac death when traditional autopsy findings are inconclusive.
