Paroxysmal Sustained Ventricular Tachycardia with Cardiac Arrest and Myocardial Infarction in 29-Year-Old Man Addicted to Medical Marijuana—It Never Rains but It Pours

Abstract

This article presents the case of a 29-year-old male patient, addicted to prescribed medical marijuana administered for mixed anxiety and depressive disorder and without classic cardiovascular risk factors and history of myocarditis, suffering from episodes of paroxysmal hemodynamically unstable ventricular tachycardia. Cardiovascular magnetic resonance imaging of the heart revealed disseminated non-ischemic myocardial injury lesions of subepicardial and intramuscular location. Additionally, the individual experienced myocardial infarction without ST segment elevation following marijuana intake. Treatment required implantation of a cardioverter-defibrillator and ablation of the myocardial areas responsible for the origin of the arrhythmia, as well as appropriate pharmacotherapy and marijuana addiction treatment.
