Summary
Amphetamine abuse can cause spontaneous coronary artery rupture, a rare but serious condition. This case highlights the link between stimulant drug use and acute cardiac events, necessitating prompt medical intervention.
Area of Science:
- Cardiology
- Toxicology
- Emergency Medicine
Background:
- Amphetamine abuse is increasingly recognized for its cardiovascular complications.
- Spontaneous coronary artery dissection (SCAD) and myocardial infarction are known risks.
- Coronary artery rupture is a rare but potentially fatal complication.
Observation:
- A 31-year-old woman presented with acute chest pain and elevated cardiac enzymes, indicative of myocardial infarction.
- Urine drug screening confirmed amphetamine use.
- Coronary angiography revealed a critical (99%) occlusion in the left circumflex artery due to an aneurysmal lesion with contrast extravasation.
Findings:
- The patient experienced a spontaneous coronary artery rupture linked to amphetamine abuse.
- Percutaneous coronary intervention with stent placement successfully restored antegrade blood flow.
- This represents the first documented case of coronary artery rupture directly attributed to amphetamine use.
Implications:
- This case underscores the critical need for considering drug-induced cardiovascular injury in patients presenting with acute coronary syndromes.
- Clinicians should maintain a high index of suspicion for amphetamine-related cardiac events.
- Further research is warranted to understand the mechanisms and prevalence of amphetamine-induced coronary artery rupture.
