Bonsai-induced Kounis Syndrome in a young male patient

Marijuana-induced ST-elevation myocardial infarction in adolescents and young adults: A case report and comprehensive review of literature

As per the Centers for Disease Control and Prevention (CDC), the incidence of myocardial infarction (MI) is reported to be 805,000 cases annually in the United States (US). Although commonly occurring in elderly individuals with underlying cardiovascular comorbidities or younger generations with familial predispositions serving as risk factors, it is extremely rare for an isolated event to occur in teenagers with a history of marijuana use. In this article, we report a rare case of ST-elevation myocardial infarction (STEMI) in a 19-year-old male with no past medical history that was attributed to marijuana use. This case report and review of literature depict a potential association between marijuana use and STEMI. We also highlight potential clinical implications to aid healthcare professionals in making an early diagnosis and achieving a timely management strategy.

Synthetic cannabinoids and ST elevation myocardial infarction

Synthetic cannabinoids cannot be detected on a standard urine drug screen (UDS), making them a convenient drug of abuse. We report the first case of ST elevation myocardial infarction (STEMI) in a young patient due to coronary artery thrombosis secondary to synthetic cannabinoid use and concurrent COVID-19 infection. A 38-year-old previously healthy male developed severe chest pain and was found to have anterior STEMI and COVID-19 infection. Coronary angiography showed acute thrombotic occlusion of the mid-left anterior descending artery that was managed with thrombectomy and stent placement. He only required supportive care for COVID-19. A comprehensive literature search revealed 34 additional cases of STEMI with synthetic cannabinoid use; majority were males (97%) with mean age of 29 years. 29 patients (85.3%) underwent coronary angiography and majority had left anterior descending artery (LAD) involvement (55%), with 13 (44.8%) undergoing stent placement. We highlight STEMI as a potentially lethal complication of synthetic cannabinoids; prompt angiography may be lifesaving.

Marijuana use and acute myocardial infarction: A systematic review of published cases in the literature

BACKGROUND AND OBJECTIVE

Marijuana use has gained popularity following legalization in the US. Marijuana can affect the heart through various mechanisms. This study aims to conduct a systematic review of published case reports of individuals with acute myocardial infarction (AMI) following marijuana use.

METHODS

We conducted a systematic review of literature, including case reports, case series, and the letter to the editor on MEDLINE. Forty-six studies were included, with a total number of 62 patients with AMI and marijuana use.

RESULTS

The mean age was 27.7 (±10.3) years with male predominance. About 3.7 g marijuana was used for an average of 9.7 years by the patients. From the cases reporting the onset of AMI symptoms, the average time was within 5 h after last marijuana use. The angiographic findings were normal in 36.8% of cases. In 42.1% of individuals, the left anterior descending coronary artery was occluded, making it the most common artery involved, followed by the right coronary artery (10.5%). Most cases were managed medically, followed by thrombectomy and stent placement, and percutaneous transluminal coronary angioplasty (PTCA). Complications included cardio-embolic stroke, and seven deaths were reported.

CONCLUSION

It is important to consider episodic marijuana use as a significant risk factor of AMI, particularly in individuals with no cardiac risk factors, as delay in management can result in fatal outcomes including increased risk of mortality.
