Methamphetamine as a risk factor for acute aortic dissection

Area of Science:

• Cardiovascular Medicine
• Toxicology
• Forensic Pathology

Background:

• Acute aortic dissection is a life-threatening vascular emergency with high mortality.
• Hypertension is a primary risk factor for aortic dissection.
• Previous reports suggest illicit drug use, including cocaine and methamphetamine, may be associated with aortic dissections.

Purpose of the Study:

• To investigate the role of drugs, particularly methamphetamine and cocaine, in acute aortic dissections.
• To identify risk factors associated with acute aortic dissections in autopsy cases.

Main Methods:

• Review of 84 medical examiner autopsies of individuals deceased from acute aortic dissections.
• Analysis of drug test results from cases where available.
• Comparison of risk factors, including hypertension and drug use.

Main Results:

• Hypertension was the most common risk factor identified.
• Methamphetamine was detected in 7 of 35 tested cases and was the second most common risk factor.
• No cases of solely cocaine-related dissection were found; one case involved both methamphetamine and a cocaine metabolite.
• No significant association was found with other drugs.

Conclusions:

• Methamphetamine use is a significant risk factor for acute aortic dissection, likely due to its hypertensive effects.
• Both methamphetamine and cocaine should be considered potential contributing factors in cases of aortic dissection.
• Further research is warranted to elucidate the relationship between stimulant drug use and aortic dissection.
