Can CBD help treat or prevent heart disease?
Few people actually know that cannabinoids can be used to maintain heart health, treat heart conditions, and lower blood pressure (just to name a few). As cannabis becomes more widely accepted, information about cannabis extracts, like CBD oil, and its potential to cure many ailments has been an eye-stopping topic in research and medical sectors alike.
In today’s article, we will be discussing the therapeutic advancements of CBD for heart health as well as updates with what’s going on in the current research.
The Endocannabinoid System, heart health, and the effects of CBD
The endocannabinoid system (ECS) consists of both the central and peripheral nervous systems. Endocannabinoids that are synthesized in the central nervous system (CNS) are involved in pain perception, motor functions, learning, memory, and stress responses, to list a few. Endocannabinoids can also be synthesized in the peripheral nervous system (PNS) including tissues of the heart, GI tract, and blood cells, where they influence inflammatory responses, blood pressure, heart rate, and vasodilation.According to the Journal of the American Heart Association, the endocannabinoid system plays a major role in the cardiovascular system, especially in disease states. CBD has been suggested as a potential therapeutic method for various disorders of the cardiovascular system.
So what’s “heart health”? What constitutes for a healthy heart?
Over the average lifetime, according to Harvard Health, the heart beats up to 2.5 billion times - pumping millions of gallons of blood (I mean MILLIONS) to every part of the body, every second of your life. This steady flow of blood carries fuel, hormones, a host of cells, oxygen, and many other compounds. When the heart stops beating, essential functions fail, almost instantaneously.The heart is a never-ending workaholic (in the best way, of course) - it performs so well, for so long, so many of us. Unfortunately, our hearts can also fail, being slowed down by a poor diet, lack of exercise, smoking, some not-so-lucky genes, and much more.
Many people can develop some form of cardiovascular disease (CVD) throughout their lifetime. Luckily, developing CVD is not inevitable. A healthy lifestyle goes a loooong way in preventing cardiovascular diseases and issues.Eating a healthy diet, exercising regularly, and lowering the amount of daily stress in your life, are key to ensuring your heart stays healthy.
WHAT IS Cardiovascular Disease (CVD)
Cardiovascular disease (CVD) is a global epidemic representing the leading cause of death in Western countries. According to the American Heart Association, 92.1 million US citizens have one more forms of CVD, with numbers expected to grow up to 44% of the US population in the next ten years. Yikes.
Cardiovascular disease refers to a group of conditions that generally involve blocked or narrowed blood vessels that can lead to a heart attack, chest pain, or stroke. Other conditions that may affect your heart's muscle, valves, or even sinus rhythm, fall under the umbrella of heart disease.
The Journal of the American Heart Association suggest that endocannabinoids may be a promising approach as a therapeutic agent for cardiovascular disease (CVD).
CURRENT THERAPEUTIC APPROACHES TO Cardiovascular Disease
A 2005 original study published in Experimental & Clinical Cardiology found that individuals who exercise on a regular basis reduce overall blood pressure and decreases LDL and total cholesterol, and increase HDL cholesterol.
In the same Experimental & Clinical Cardiology paper noted above, researchers concluded that a plant-based diet can help prevent and potentially reverse coronary artery disease ( also referred to as CAD - this falls within the CVD umbrella too). Coronary events were shown to be reduced by 70%-73% in all-cause mortality in the plant-based diet individuals.
3) CBD Oil
A 2012 article published in the British Journal of Clinical Pharmacology made an impactful footprint on the role of cannabinoids and the cardiovascular system.Researchers found that CBD treatment protects against heart damage and cardiomyopathy, which is associated with diabetes. Similarly, CBD has been shown to reduce infarct size (aka tissue legion). CBD also reduces the cardiovascular response to models of stress. In addition, CBD influences the survival and death of white blood cells, migration, and platelet aggregation in blood.
These preclinical data findings appear to support a positive role for CBD oil and heart health.
CBD For Congestive Heart Failure
When a person has congestive heart failure, the expression of the cardiomyocytes, heart muscle cells, and endothelial cells change as well as the amount of circulating immune cells. In cardiomyocytes and endothelial cells,CB2 receptors initiate inflammation and CB1 receptors promote cardiac dysfunction, even cell death.Published in the Journal of the American Heart Association in 2018, CB1 antagonism and CB2 agonism were suggested to be anti-atherogenic. A specific CB1 antagonist can be used to treat obesity and reduce the progression of atherosclerosis by lowering proinflammatory cytokines.
Cannabidiol therapies directed at the ECS may relax human pulmonary arteries in an endothelium-independent manner.
Effects of CBD on Heart Rates and Arrhythmia
Frontiers in Pharmacology published a systematic review and meta-analysis in 2017 summarizing the effects of cannabidiol. Of the 22 publications assessed, CBD had no effect of blood pressure (BP) and heart rate (HR) in controlled conditions. During stressful situations, CBD administration significantly was shown to reduce the increase in blood pressure and heart rate that was induced by stress. One study included in this systematic review and meta-analysis assessed CBD administration on cardiac arrhythmias and found no change in BP.
CBD was suggested to have no effect on blood pressure, heart rate, and cardiac arrhythmias.
Does CBD Lower Blood Pressure?
In 2017, researchers studied the effects of a single dose of CBD and its effects on blood pressure in a randomized cross over study. The participants were healthy male volunteers who were placed in a randomized, placebo-controlled, double-blind, crossover study to either 600 mg of CBD or a placebo. Researchers found that CBD-treated participants showed reductions in resting blood pressure, reductions in stroke volume, increases in heart rate, and maintenance in cardiac output.
This recent study found that one dose of CBD was effective in lowering blood pressure.
Does CBD Increase Blood Pressure
In 2012, researchers reviewed cannabidiol as a therapeutic target for the cardiovascular system. They found that CBD treatment, in vivo, did not appear to have any effect on resting blood pressure or heart rate, but did show reductions in cardiovascular response to various scenarios of stress.
This review presented evidence of CBD having positive effects in the cardiovascular system.
Effects of CBD on Blood Pressure
A 1999 study performed on mice found that CBD treated mice had similar blood pressures to vehicle-treated mice. The CB1 receptors involved in the control of blood pressure were shown to be tonically inactive. Regardless of the mechanisms involved, cannabinoid-induced vasodilation may have therapeutic implications on vascular diseases.
Blood pressure may not change significantly with CBD intake.
Cardiovascular Disease (CVD) MANAGEMENT & TREATMENT
There are different options that individuals can consider for treating CVD, naturally and with pharmaceutical regimens.Natural treatments include: Drug regimens include:
- Lifestyle changes/adjustments Antihypertensive agents
- Increased physical activity Statins
- Changing to a healthy diet Beta-blockers
- Losing excess weight Blood-thinning medications
- Stopping smoking
- Decreasing stress
- CBD oil
For most individuals, a combination of both options listed above can help reduce your risk of developing CVD. Just like making a delicious smoothie, you add a combination of ingredients to get your ideal drink!
When considered together, the options reported above show that the probability of heart attack events or stroke is decreased with long-term regular exercise. These vascular angiogenic effects developed by physical activity, lend additional support to the hypothesis that exercise is tremendously beneficial for the cardiovascular system. Individuals who exercise on a regular basis after having a heart attack lower their risk of death by 20-25% compared to individuals who don’t exercise after having their first heart attack.A 2010 study by Walsh et al. analyzed the administration of cannabidiol in cardiac arrhythmias and infarct size. Researchers found that not only did CBD demonstrate cardioprotective characteristics by reducing ventricular arrhythmias, but also attenuating infarct size.
Research On the effects of CBD Oil and Cardiovascular Heart Health
According to the World Health Organization, cannabidiol (CBD) is generally well tolerated with a good safety profile. Preclinical studies show that CBD has numerous cardiovascular benefits.
This study found that one single dose of CBD was shown to reduce resting blood pressure.
A recent 2017 study published in JCI Insight assessed the effects of a single dose of cannabidiol in a randomized crossover study. Nine healthy male volunteers were either given 600 mg of CBD or a placebo. Researchers demonstrated that CBD administration reduced resting systolic blood pressure and stroke volume, increased heart rate, and maintained cardiac output.
CBD may be used as a treatment for various cardiovascular disorders, such as hypertension, heart attack, and stroke.
A 2017 systematic review and meta-analysis of the hemodynamics effects of cannabidiol discussed important findings in the cannabidiol literature, thus far. CBD did not affect hemodynamics under control conditions per se, however, the analysis did reveal the effects of CBD in pathological situations. CBD may regulate the hemodynamics when altered at times of stress or acute illness.
Conclusion: Using CBD Oil As Treatment For Congestive Heart Failure
Let’s put this heart back together now, shall we?
Whether individuals are in prevention, treatment, or management stages of cardiovascular disease, CBD oil holds true as a therapeutic, all-natural method for reducing inflammation, blood pressure, stroke volume, infarct size, and overall cardiovascular disorders. These studies suggest that the cardiovascular system is a valid and therapeutic target for CBD.
However, more human subject research studies are needed to fully determine and assess the efficacy of CBD oil as a treatment for CVD. Large sample size, randomized, controlled trials are needed to better assess the benefits of CBD oil, including their effects on CVD and hemodynamics. Until then, the systematic reviews and original articles suggesting that CBD has positive effects on CVD hold promise.
