Postmortem biochemistry in deaths from ischemic heart disease

Area of Science:

• Forensic Pathology
• Biochemistry
• Cardiology

Background:

• Ischemic heart disease (IHD) is a major cause of global mortality and sudden cardiac death.
• Diagnosing early-stage IHD in postmortem examinations is challenging with current histopathological methods.
• Postmortem biochemistry offers a promising avenue for accurate diagnosis in forensic cases.

Purpose of the Study:

• To review and summarize biomarkers studied for diagnosing IHD-related deaths in postmortem biological fluids.
• To assess the potential of clinical myocardial infarction biomarkers in forensic applications.
• To highlight the need for further research into postmortem biomarker stability and application.

Main Methods:

• Literature review of studies on IHD biomarkers in autopsy samples and animal experiments.
• Analysis of existing research on the reliability of clinical biomarkers in postmortem settings.
• Identification of key variables affecting postmortem biomarker stability.

Main Results:

• The postmortem application of biochemical markers for IHD diagnosis shows encouraging results.
• Existing clinical biomarkers for myocardial infarction may be adaptable for postmortem use.
• Significant differences exist between clinical and postmortem biochemistry due to postmortem dynamics.

Conclusions:

• Postmortem biochemistry is a valuable tool for diagnosing IHD, but requires further validation.
• Comprehensive studies are essential to evaluate biomarker stability, significance, and influencing factors (e.g., postmortem interval, medications).
• Establishing validated cut-off values for biomarkers is crucial for routine forensic application in IHD deaths.
