What This Study Found

Coronary angiography revealed a mobile thrombus in the left main coronary artery, a rare and potentially fatal finding, in a young male cannabis consumer. The patient was successfully treated with manual aspiration thrombectomy, dual antiplatelet therapy, and unfractionated heparin.

Key Numbers

Young male patient; left main coronary artery thrombus; non-ST-elevation myocardial infarction; treated with manual aspiration, dual antiplatelet therapy, and heparin

How They Did This

Single case report documenting clinical presentation, coronary angiography findings, and management of left main coronary thrombus in a young cannabis user presenting with non-ST-elevation myocardial infarction.

Why This Research Matters

Left main coronary thrombus is a life-threatening finding usually associated with atherosclerotic plaque rupture. Its occurrence in a young cannabis user without typical risk factors raises questions about cannabis as a prothrombotic trigger.

The Bigger Picture

This case adds to accumulating reports of acute coronary events in young cannabis users and suggests cannabis may promote coronary thrombosis through mechanisms distinct from traditional atherosclerotic risk factors.

What This Study Doesn't Tell Us

Single case report. Cannot prove cannabis caused the thrombus. Other prothrombotic factors may not have been fully evaluated. No systematic comparison to other cases.

Questions This Raises

  • ?What is the mechanism by which cannabis might promote coronary thrombosis?
  • ?Is this risk related to frequency, method, or potency of use?
  • ?How often do young cannabis users present with coronary thrombosis without being recognized?

Frequently Asked Questions

Is a left main coronary thrombus common?

No. It is a rare angiographic finding typically associated with very serious outcomes including sudden death and cardiogenic shock. Its occurrence in a young person without typical risk factors is particularly unusual.

Did the patient survive?

Yes. The patient was successfully treated with manual blood clot removal, blood-thinning medications, and antiplatelet therapy.
