Cardiovascular Disease in Acute Cocaine Compared to Acute Fentanyl Intoxication Deaths

Area of Science:

• Forensic Toxicology
• Cardiovascular Pathology
• Public Health

Background:

• Cocaine is a leading cause of stimulant-related fatalities.
• Cocaine-induced deaths are often idiosyncratic, linked to cardiovascular events.
• Opioid intoxication deaths typically correlate with drug concentration.

Purpose of the Study:

• To investigate the association between cardiovascular disease and sole cocaine intoxication deaths.
• To compare the prevalence of cardiovascular disease in cocaine versus fentanyl intoxication deaths.
• To elucidate the mechanisms contributing to cocaine and fentanyl-related fatalities.

Main Methods:

• Retrospective analysis of autopsy and toxicology data.
• Examination of 78 sole acute cocaine intoxication deaths.
• Assessment of 306 sole acute fentanyl intoxication deaths for cardiovascular disease.

Main Results:

• 87% of cocaine deaths involved atherosclerotic and/or hypertensive cardiovascular disease.
• 40% of fentanyl deaths involved cardiovascular disease.
• Sole cocaine deaths showed a significantly higher prevalence of co-existing heart disease compared to sole fentanyl deaths (P < 0.001).

Conclusions:

• Cardiovascular disease plays a significant mechanistic role in sole cocaine intoxication deaths.
• Fentanyl's potency appears to be the dominant mechanism in fentanyl-related deaths.
• The high co-occurrence of heart disease in cocaine fatalities suggests a critical interaction between the drug and pre-existing cardiac conditions.
