Marijuana-induced acute myocardial infarction in a young adult male.

ABSTRACT

A 27-year-old man presented to the emergency department of a tertiary care centre with complaints of acute onset breathing difficulty and retrosternal chest discomfort of 6 hours' duration. On primary survey, he was dyspnoeic with a room air saturation of 85% and a blood pressure of 80/50 mm Hg. A bedside ultrasound revealed an ejection fraction of around 40%, with hypokinesia of interventricular septum, left ventricular apex and anterior wall with bilateral multiple B lines in all lung zones. A 12 lead ECG showed ST segment elevation in leads V2-V6. He sustained a cardiac arrest. Return of spontaneous circulation was achieved following high-quality cardiopulmonary resuscitation. After successful resuscitation, the patient underwent primary percutaneous coronary intervention and recovered fully from the event. On further evaluation, an acute binge of marijuana smoking prior to the onset of symptoms was identified as the cause of the acute coronary syndrome.
