humulene and Takotsubo-Cardiomyopathy

Recently, an association between cannabis use and Takotsubo (stress) cardiomyopathy (TTC) has been shown. With the current trend of legalization of cannabis, it is important to understand brain effects of cannabis use that could lead to cardiac disease, such as TTC. Here we review recent brain imaging studies in order to search for the evidence supporting the association between cannabis use, stress, and TTC.. There exist brain imaging studies showing similar findings across TTC, stress, and cannabis use. These similar findings are mainly centered on a key central autonomic network region amygdala, i.e., amygdala hyperactivity/hyperconnectivity when exposed to challenge, stress, or negative stimuli. This similarity supports a close association among cannabis use, stress, and TTC. Amygdala-centered neuronal circuits could underlie cannabis use as risk factor to TTC. Based on the findings, several directions for future studies are proposed.

Recent reports suggest a link between increased cannabis (marijuana) use and stress-cardiomyopathy (Takotsubo Syndrome, TTS) and related complications. Amidst recent trends in cannabis legalization and a paucity of data, it remains essential to evaluate the prevalence, trends and outcomes of TTS in cannabis users on a large-scale.. We studied prevalence and trends in TTS among adult cannabis users vs. non-users using the National Inpatient Sample (2007-2014). Baseline characteristics, comorbidities, and in-hospital outcomes of TTS were compared between cannabis users vs. non-users. Weighted logistic regression was performed adjusting for confounders to estimate the inpatient outcomes of TTS with vs. without cannabis use.. The overall prevalence of TTS in cannabis users (47/100,000) was lower as compared to non-users (62/100,000). Rising trends in TTS among cannabis users (<11 to 82, ~8-fold) were more pronounced as compared to non-users (19 to 108, ~6 fold) per 100,000 hospitalizations from 2007 to 2014 (p. Cannabis users showed lower prevalence but a more pronounced rising trend of TTS and subsequent risk of in-hospital mortality compared to non-users.
