Can CS gas induce myocardial infarction?

Area of Science:

• Toxicology
• Cardiology
• Emergency Medicine

Background:

• 2-chlorobenzylidene malononitrile (CS gas) is the most prevalent riot-control agent globally.
• CS gas is perceived as less toxic, leading to widespread use by authorities.
• Limited safety data exists for CS gas, with potential for severe health effects upon heavy exposure.

Observation:

• A case report of a young man experiencing acute myocardial infarction (heart attack) is presented.
• The myocardial infarction occurred following exposure to tear gas.
• This event led to serious cardiac sequelae in the patient.

Findings:

• The study documents a direct link between CS gas exposure and acute heart infarction.
• This is only the second documented case in 40 years connecting CS gas exposure to myocardial infarction.
• The findings suggest CS gas may pose significant cardiovascular risks.

Implications:

• This case highlights the under-recognized cardiovascular risks associated with CS gas exposure.
• Further research is warranted to understand the mechanisms and prevalence of CS gas-induced cardiac events.
• Clinicians should consider CS gas exposure in the differential diagnosis of myocardial infarction, especially in relevant populations.
