Abstract

Background

The United States has recently undergone increases in the legalization and use of marijuana. There have been previous reports on the association of cannabis use and myocardial dysfunction, however, few on the association with acute stress cardiomyopathy and cardiogenic shock.

Case Report

This is a case of a 58-year-old female with a history of inhaled cannabis use, no history of diabetes, and no known history of cardiac disease, that illustrates an association between cannabis use and the recurrent development of stress cardiomyopathy and cardiogenic shock. A review of medical records was performed from two hospitalizations and subsequent outpatient follow-up for similar presentations 6 years apart and review of literature regarding cannabis use and its association with cardiac dysfunction. In separate hospitalizations, the patient presented with clinical findings of cardiogenic shock, severe left ventricular dysfunction with morphologic features of stress cardiomyopathy, and normal coronary angiography. Laboratory results included elevated cardiac biomarkers and urine tetrahydrocannabinol levels > 300 ng/mL. The patient required intensive cardiovascular support, but recovered with normal cardiac function after each event.

Why Should an Emergency Physician Be Aware of This?

As use of cannabis becomes more prevalent, it will be important for physicians to recognize the potential association of cannabis use and acute myocardial dysfunction, and how early treatment may contribute to salutary outcomes.
