Heart disease usually includes conditions such as arteriosclerosis, which is the blocking or narrowing of blood vessels, meaning the arteries of the heart cannot deliver enough oxygen-rich blood to the heart, which could lead to some strokes, angina, or a heart attack. According to the World Health Organization, Cardiovascular diseases (CVDs) are the number 1 cause of death globally, taking an estimated 17.9 million lives each year. The CDC report that one person dies every 36 seconds In the United States from heart disease. Some of the key risk factors for heart disease include high blood pressure, high cholesterol and smoking, as well as uncontrollable factors such as age or family history.
Research has been showing that CBD can potentially maintain healthy cardiovascular function and prevent heart disease on a number of fronts, including against arteriosclerosis, lowering blood pressure and reducing the incidence of potentially dangerous arrhythmias.
High blood pressure is the leading risk factor for hypertensive heart disease. Your blood pressure can rise under stress, but some research suggests a dose of CBD can lessen that spike.
Resstel et al. (2009) study examined rodents that were subjected to a stressful situation that caused their blood pressure and heart rate to increase. A dose of CBD lowered both their blood pressure and heart rate.
Jadoon, Tan & O’ Sullivan (2017) made a similar study only with human volunteers that were subjected to situations that caused increased blood pressure and heart rate. The he CBD lowered their blood pressure, as compared to volunteers given a placebo.
However, a 2017 empirical study by Sultan et al. (2017) s found that there’s no evidence that CBD provides similar results under non-stressful conditions. Talk to your doctor before using CBD if you have high blood pressure. So, while more research is needed to say for sure, CBD may be useful in lowering blood pressure and heart rate under stress.
