The effects of cannabis use on major adverse cardiovascular outcomes, mortality, cost of hospitalization, and cardiac arrhythmias: A Retrospective analysis using the national inpatient sample

Abstract

As cannabis use is rising and federal restrictions are easing, it is important to recognize its potential adverse cardiovascular effects for better risk stratification and informed guidance. We conducted a retrospective study using the National Inpatient Sample database from 2016 to 2019, where 39,992 subjects were enrolled. The extracted population was classified into two groups based on the presence of cannabis-related disorders. The primary outcomes of the study were cardiovascular-related adverse events, in-hospital mortality, total cost of hospitalization, and cardiac dysrhythmias. The study concluded that cannabis use disorder was not significantly associated with the likelihood of having a cardiovascular adverse event, cardiac dysrhythmias, or with the cost of hospitalization when controlling for other variables (p = 0.257, p=0.481 & p = 0.481, respectively). However, it was significantly associated with the likelihood of mortality (p < 0.0001). Further randomized trials are needed to confirm these findings and elaborate on identified associations.
