Cannabis-induced basal-mid-left ventricular stress cardiomyopathy: A case report
International Journal of Critical Illness and Injury Science
Cannabis, popularly known as marijuana, is a recreational drug derived from the plant Cannabis Sativa. It has been recognized as the most widely used mood-altering substance in the world and is falsely perceived as a safe substance by the public at large. This is mostly due to lack of awareness of its adverse effects as well as successful attempts for legalization of its use in many states. We present a unique case of a 56-year-old man who presented with neurological deficits concerning for stroke. Soon after presentation, he required endotracheal intubation for airway protection due to worsening mental status changes and pulmonary edema. Echocardiogram revealed severe hypokinesis of the basal and mid-left ventricular (LV) walls with hyperdynamic motion of the apex (reverse takotsubo). Coronary angiography revealed no obstructive disease. Urine toxicology screen was positive for Δ-9-tetrahydrocannabinol. The patient then stated to have used excess marijuana before the symptom onset, while denying any recent emotional stressors. The findings were consistent with stress cardiomyopathy (SC) triggered by marijuana use. Myocardial infarction, stroke, and peripheral arteriopathy have been increasingly reported in younger individuals using marijuana. SC appears to be another unique complication of marijuana use triggered through its effects on the autonomic nervous and endocannabinoid systems.
