Proteomics in Cardiovascular Deaths, a Postmortem Pilot Study: The Diagnostic Efficacy of α-1 Antitrypsin and Apolipoprotein A-IV in Ischemic and Congestive Deaths

: Postmortem cardiac proteomic profiling reveals biologically coherent molecular signatures associated with different cardiovascular causes of death. Although further validation in larger independent cohorts is required, ApoA-IV emerges as a promising candidate biomarker for ischemic cardiac death. Multimarker proteomic strategies may complement traditional autopsy to enhance diagnostic accuracy in forensic investigations, particularly in cases with equivocal morphological findings.
