Background: Cardiac disease is accounted as the leading cause of worldwide morbidity and mortality, mainly in association with induction of inflammation and oxidative stress. The disease is characterized by the overproduction of reactive oxygen and/or nitrogen species (ROS/RNS), and reduced antioxidant capacity. Cannabidiol (CBD) is a non-psychoactive ingredient of marijuana that reported to be safe and well tolerated in patients. Due to its pleiotropic effect, CBD has been shown to exert cytoprotective effects. This study intended to clarify the mechanisms and the potential role of CBD regarding cardiac injuries treatment.
Methods: A systematic literature search was conducted, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, in the electronic databases including PubMed, Web of Science, Scopus, and Embase up to July 2018 using predefined search terms in the titles and abstracts by two independent investigators. Accordingly, a set of pre-specified inclusion and exclusion criteria were considered and 8 articles were ultimately included in this study.
Results: Our findings obviously demonstrate that CBD has multi-functional protective assets to improve cardiac injuries; preliminary through scavenging of free radicals, and reduction of oxidative stress, apoptosis, and inflammation.
Conclusion: CBD can protect against cardiac injuries, mainly through its anti-oxidant, anti-inflammatory, and anti-apoptotic effects on the basis of non-clinical studies.
