Methamphetamine-Induced Coronary Vasospasm and Recurrent Cardiac Arrest: A Quick Glance May Not Be Good Enough.

ABSTRACT:

Background

Methamphetamine can cause coronary vasospasm and atherosclerotic plaque disruption, leading to myocardial ischemia and tachyarrhythmias.

Case summary

A 51-year-old man experienced recurrent episodes of polymorphic ventricular tachycardia (PMVT) and cardiac arrest after using methamphetamine. Initial coronary angiography (CA) revealed diffuse multivessel coronary artery disease; therefore, percutaneous coronary intervention was deferred. On day 12 of hospitalization, he developed acute anterior ST-segment elevation myocardial infarction complicated by PMVT and cardiac arrest. Repeat CA revealed only a single focal culprit lesion in the mid-left anterior descending artery. This was simply treated with a single drug-eluting stent.

Discussion
