Abstract:
Cocaine has become the most frequently used illicit drug among patients presenting to emergency departments worldwide. Although acute myocardial infarction is the most common reported cardiovascular manifestation in this setting, there are many other potential cardiotoxic effects of cocaine use including coronary artery spasm, arrhythmia, and sudden death. We report the case of a 54 year-old male with angiographically documented reversible coronary arterial spasm leading to severe life-threatening recurrent ventricular arrhythmias and electrocardiographic changes suggesting acute myocardial infarction secondary to cocaine use. Recurrent ventricular arrhythmias of this patient required implantation of a cardioverter-defibrillator which successfully treated following arrhythmia episodes.
