Incidental Acute ST Elevation Due to Cannabis-Induced Myocarditis After a Mechanical Fall

Paroxysmal Sustained Ventricular Tachycardia with Cardiac Arrest and Myocardial Infarction in 29-Year-Old Man Addicted to Medical Marijuana-It Never Rains but It Pours

This article presents the case of a 29-year-old male patient, addicted to prescribed medical marijuana administered for mixed anxiety and depressive disorder and without classic cardiovascular risk factors and history of myocarditis, suffering from episodes of paroxysmal hemodynamically unstable ventricular tachycardia. Cardiovascular magnetic resonance imaging of the heart revealed disseminated non-ischemic myocardial injury lesions of subepicardial and intramuscular location. Additionally, the individual experienced myocardial infarction without ST segment elevation following marijuana intake. Treatment required implantation of a cardioverter-defibrillator and ablation of the myocardial areas responsible for the origin of the arrhythmia, as well as appropriate pharmacotherapy and marijuana addiction treatment.

Marijuana-induced toxic myocarditis: a case report and a review of the literature

Cannabis consumption has increased over the past decade, together with its application in the medical field.1 Therefore, close monitoring of the potential harm to public health caused by its use is required. Many of the related health implications of cannabis include cardiovascular diseases.2 In young adults with a history of cannabis use, higher frequency of admission for acute myocardial infarction, arrhythmia and stroke were described in a recent study.3 Although rare, cases of marijuana-induced toxic myocarditis have been reported in literature.4-11 This study examines a case of a young male patient with acute myocarditis following marijuana use.

Marijuana-induced myocarditis in a 24-year-old man

As marijuana, the most widely-used illicit drug in adolescents and adults, has some unknown side effects, marijuana abuse has become a public health concern. Also, marijuana affects different organs such as heart in its rate, rhythm and coronary flow; it eventually leads to events such as myocardial infarction and rarely myocarditis. A 24-year-old man without any medical history or cardiovascular risk factors presented with chest pain after marijuana consumption. Based on electrocardiogram, myocardial cytolysis and transthoracic echocardiography acute myocarditis diagnosis was established. A few days later, transthoracic echocardiography showed a small clot in apex with reduced left ventricle ejection fraction, in the absence of local akinesia. The patient was discharged with oral anticoagulant stable and without any symptoms. The myocarditis after marijuana abuse is rare. The physicians should include acute myocarditis in differential diagnosis of a patient with chest pain after using marijuana.

COVID-19 Vaccine Cardiac Complications: A Case Series on Implications of Marijuana in Adolescents With Myopericarditis

We report on two critically ill pediatric patients, aged 16 and 18 years, presenting with acute myopericarditis at a tertiary-care center in New Jersey, United States. Both patients had their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations, tested negative for SARS-CoV-2, and shared only significant history of asthma. Clinical presentations were similar to acute onset chest pain that worsened with deep inspiration. One patient reported a history of vaping and escalating marijuana use several hours preceding presentation. Both patients had elevated troponin on admission and had ST-segment elevation on electrocardiogram (EKG), thus prompting admission to the pediatric intensive care unit (PICU) for cardiac monitoring. Myopericarditis has multiple etiologies and is a newly described rare complication of the SARS-CoV-2 vaccine. It can also occur as a complication of vaping and frequent marijuana drug use. Our paper highlights the importance of a detailed social and drug history in adolescents presenting with chest pain. The clinical characterization is necessary to promote better case definitions and the design of targeted interventions for this vulnerable group.
