Myocardial infarction and marijuana.

R Charles, S Holt, N Kirkham

    Clinical Toxicology
    |April 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    A young man experienced a heart attack (myocardial infarction) after smoking marijuana, despite having no traditional risk factors. Coronary angiography revealed no blockages, suggesting a non-atherosclerotic cause.

    Area of Science:

    • Cardiology
    • Toxicology
    • Cannabinoid Research

    Background:

    • Myocardial infarction (MI) typically occurs in individuals with established cardiovascular risk factors.
    • Marijuana use is increasingly prevalent, with potential cardiovascular effects under investigation.

    Observation:

    • A 25-year-old male presented with symptoms of myocardial infarction.
    • The patient reported smoking a marijuana cigarette shortly before symptom onset.
    • The individual had no significant traditional cardiovascular risk factors (e.g., hypertension, hyperlipidemia, diabetes, smoking history).

    Findings:

    • Coronary arteriography performed after the event was normal, showing no obstructive coronary artery disease.
    • This suggests the myocardial infarction was not caused by typical atherosclerosis.

    Implications:

    • The findings raise concerns about the potential for marijuana use to trigger acute cardiovascular events, even in young, otherwise healthy individuals.
    • Further research is needed to elucidate the mechanisms by which marijuana may induce myocardial infarction, potentially through vasospasm or other non-atherosclerotic pathways.
    • This case highlights the importance of considering marijuana use in the differential diagnosis of myocardial infarction in young adults.
