“Cannabidiol (CBD) is the second most abundant phytocannabinoid, after Δ9-tetrahydrocannabinol (THC) and was first isolated from the cannabis extract in 1940.

Given the increasing clinical use of CBD, and the numerous effects of CBD in the cardiovascular system, the aim of the present study was to systematically review and analyse in vivo studies evaluating the effects of CBD on alterations in haemodynamics.

From the limited data available, we conclude that acute and chronic administration of CBD had no effect on BP or HR under control conditions, but reduces BP and HR in stressful conditions, and increases cerebral blood flow (CBF) in mouse models of stroke.

This meta-analysis and systematic review has highlighted the haemodynamic effects of CBD administration in vivo.

The positive effects induced by CBD include maintaining the fall in BP after global hypoxia, reducing the increase in MBP and HR post-stress, and increasing BF in ischaemia-reperfusion models.

It is possible that beneficial effects of CBD on haemodynamics occurs when the cardiovascular system is abnormally altered, suggesting that CBD may be used as a treatment for various cardiovascular disorders, such as hypertension, myocardial infarction and stroke.”
