Because I Got High: Marijuana Induced Pseudo-Wellen's Syndrome

Abstract

Wellen's syndrome is a pattern on ECG that signifies impending acute myocardial infarction (MI) of the proximal left anterior descending (LAD) artery. This same pattern can also be noted in several benign diseases that may mimic Wellen's syndrome. Here we discuss a 36-year-old patient with no cardiac risk factors who presented with typical angina shortly after smoking marijuana. Upon arrival to the ED, an electrocardiogram revealed new biphasic T wave inversions in the anterolateral leads and cardiac biomarkers were found to be elevated. The patient was taken for emergent coronary angiography which revealed widely patent coronary arteries. Soon after, the patient was diagnosed with Pseudo-Wellen's syndrome secondary to cannabis use. This case report highlights the importance of identifying causes that may resemble Wellen's syndrome, especially in young adults without risk factors for acute coronary syndrome (ACS). Recognizing these cases can help avoid further invasive diagnostic testing, along with the complications that may go along with it.
