“…Marijuana, the most common drug of abuse, is one of the Cannabis sativa L plants family which contains tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabinol (CBN) and has different effects on animals and human [15]. Marijuana has different receptors in body tissues and may affect the cardiovascular system by platelet aggregation, coronary spasms and marijuana-induced arteritis and lead to increased heart rate, systolic and diastolic blood pressures, sympathetic nervous system hyperactivity, myocardial infarctions (MIs) in young patients and coronary arterial vasospasm [16,17].…”

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

et al. 2022

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.

“…The diffuse late gadolinium enhancement lesions, located in the lateral, inferolateral or inferior wall with a midwall to subepicardial distribution, without oedema, hyperemia/capillary leakage with irreversible injury of necrosis/fibrosis indicate past myocarditis, not only of infectious background also of toxic myocarditis like a marijuana-related one [ 6 , 7 , 8 ]. Recent years have yielded multiple cases of cannabis-induced myocarditis varying from asymptomatic cases to end-stage cardiomyopathy and death [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Noteworthy, marijuana contains more than 460 active chemical compounds including THC which acts via the CB1 and CB2 receptors that are widely distributed in different tissues of the body.…”

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.

“…Only eight other cases have been described in the literature to date (Table 1). [4][5][6][7][8][9][10][11] Notably, in three of them, the diagnosis was based only on clinical, biochemical and ECG assessments, 5,8,10 whereas in a further three cases the diagnosis was confirmed by means of histological examination. 4,7,9 Only in two cases did the CMR play a decisive role in formulating the final diagnosis.…”

“…4,7,9 Only in two cases did the CMR play a decisive role in formulating the final diagnosis. 6,11 Nowadays, the CMR role has been well defined. It represents the noninvasive gold-standard method for the diagnosis of myocarditis (class I recommendation, level of evidence C in the 2021 ESC guidelines).…”

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.
