This report is the first to describe coronary vasospasm, diagnosed by cardiac magnetic resonance imaging in an adolescent, resulting from marijuana abuse. A previously healthy 17-year-old male patient with severe chest pain, electrocardiographic changes, and urine test positive for cannabis, was diagnosed of having transient myocardial ischemia. The patient was discharged home and at this writing remains asymptomatic with a follow-up echocardiogram after 1 month showing normal left ventricular systolic function. Marijuana should be considered in the etiology of transient coronary vasospasm leading to myocardial ischemia in otherwise healthy adolescents. Cardiac magnetic resonance imaging is a safe and effective method for diagnosing coronary vasospasm.
本报告首次描述了一名青少年因滥用大麻导致冠状动脉痉挛，该诊断通过心脏磁共振成像得出。一名此前健康的17岁男性患者，出现严重胸痛、心电图改变，尿液检测大麻呈阳性，被诊断为短暂性心肌缺血。患者出院回家，在撰写本文时仍无症状，1个月后的随访超声心动图显示左心室收缩功能正常。对于原本健康的青少年，在导致心肌缺血的短暂性冠状动脉痉挛病因中应考虑大麻因素。心脏磁共振成像是诊断冠状动脉痉挛的一种安全有效的方法。
