What research says about CBD and heart disease. CBD's anti-inflammatory and antioxidant properties may reduce risk factors that can cause heart disease, such as high blood pressure. It can also lower the risk of related conditions, such as a stroke. Although acute or chronic CBD treatment appears to have little effect on hemodynamics, CBD reduces the cardiovascular response to stress models, applied systemically or intracranially, inhibited by a 5HT1A receptor antagonist.
In addition, while the FDA has approved some CBD drugs to treat certain diseases, don't expect over-the-counter CBD to be safe or beneficial for heart failure, Lundgren says. In addition to the effects of CBD on the heart and vasculature, there is evidence that CBD also influences blood cell function. Taken together, these studies show that CBD influences both white blood cell survival and death, white blood cell migration and platelet aggregation, which could underpin CBD's ability to delay or prevent the development of cardiovascular disorders.
