Will Mary Jane Leave You Heartbroken? Marijuana Use and Risk of Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TTC) is prevalent in 2% of patients who present with symptoms suggestive of acute myocardial infarction. It may be triggered by stressful events, resulting in catecholamine surges, myocardial stunning, and disturbances in contractility. TTC in males has been associated with marijuana use and leads to a fivefold increased risk of cardiac events. Marijuana is thought to generate a similar surge in catecholamines leading to tachycardia and elevation of both systolic and diastolic blood pressure. The question remains whether this catecholamine surge is sufficient enough to cause TTC. It is apparent a correlation between marijuana use and TTC may exist. Exogenous cannabinoid stimulation may lead to myocardial stunning via stimulation seen with hypercatecholaminergic states. Understanding the risk factors involved and increasing awareness of cardiovascular complications related to cannabinoid substances becomes more relevant as its use is increasing both recreationally and medically. We present a case of a 50 year-old African-American male with hypertension and regular marijuana use who presented with chest pain radiating to the back. Due to abnormal electrocardiogram and positive cardiac biomarkers concerning for acute coronary syndrome, the patient underwent subsequent coronary angiography that showed no significant coronary obstruction; however, left ventriculogram showed the characteristic apical ballooning of TTC. Our case highlights the pathophysiological mechanism suspected to trigger TTC.
