"Heart disease is the number one threat to human life and health, and cardiovascular disease has long been the world's leading cause of mortality and one of the major diseases threatening the health of the global population."
1.Facts and figures about heart disease
If a person has an average heartbeat of 65 beats a minute and a life expectancy of 80 years, their heart can beat more than 2.7 billion times in their lifetime. The heart provides us with varying degrees of blood oxygen and power at every happy moment, at times of stress, during exercise and at quiet times.
According to the WHO, approximately 17.9 million people die of heart disease each year worldwide, accounting for 31% of all deaths. On average, one person dies of sudden cardiac death every one minute in the world.
The development of heart disease is influenced by many factors. Genetics, high blood pressure, age, alcohol consumption, smoking, obesity, high blood cholesterol, diabetes, sleep, diet, exercise and emotional stress all have an impact.
Heart disease is a condition that occurs when the arteries of the heart are unable to deliver enough oxygen-rich blood to the heart.
The main risk factors for heart disease include unhealthy diet, physical inactivity, diabetes, overweight and obesity, and excessive alcohol consumption.
Similarly, strokes occur when the blood flow to the brain is blocked or reduced.Therefore, preventive measures for heart disease and other cardiovascular diseases (such as diet, exercise and a healthy lifestyle, including CBD supplementation) can also help prevent stroke. CBD can also play a key role in protecting the brain after a stroke.
2.Impact of CBD on arteries
Studies have shown that CBD can help maintain healthy cardiovascular function and prevent heart disease in many ways, including preventing atherosclerosis, lowering blood pressure and reducing the incidence of potentially dangerous arrhythmias.
Starting with your arteries, when the inner walls of your arteries are injured, they form plaques that cause them to narrow. This is called atherosclerosis; it is a common form of heart disease. Inflammation is the main cause of this type of damage, as is high blood pressure. In animal studies, long-term exposure to small doses of CBD has been shown to slow the progression of atherosclerosis.
CBD is a vasodilator, which means it dilates blood vessels, a process regulated by the endocannabinoid system, which has a significant positive effect on blood pressure. In a 2017 study, British researchers gave a group of men 600 mg of CBD or a virtual supplement and monitored their blood pressure at rest, as well as after a stress test that would normally increase blood pressure. A single dose of CBD reduced the subjects' resting systolic blood pressure by 6 mm Hg. In addition, their peak blood pressure under stress was smaller than those taking a single dose of placebo.
Lead researcher Dr. Saoirse E. O'Sullivan said, "The reduction in arterial stiffness and the improvement in internal carotid artery blood flow and endothelial function after long-term CBD administration suggest a positive effect on vascular function and warrant further study in the relevant patient population."
3. CBD can Prevent Arrhythmias or Arrhythmias
CBD can also prevent arrhythmias or arrhythmias, which are conditions in which the heart beats too fast, too slow or irregularly. Chronic stress can lead to arrhythmias because high cortisol levels raise blood pressure, blood cholesterol, blood sugar, triglycerides and the risk of other heart conditions.
The anxiolytic properties of CBD may help combat stress, lower cortisol and prevent arrhythmias associated with these causes.
Research have shown that CBD can also suppress ischaemia caused by stroke and irregular heartbeat caused by inadequate blood supply to the heart, and can minimise tissue damage caused by hypoxia.
A study published in the British Journal of Pharmacology found that when rats were given CBD during 30 minutes of coronary occlusion (partial or complete blockage of coronary blood flow, which can lead to chest pain, heart attack and tissue damage). When CBD was administered in the first 10 minutes or 10 minutes before blood flow was restored, they experienced fewer arrhythmias and less tissue damage compared to rats not given CBD.
As cannabinoids also scavenge free radicals and improve the action of other antioxidants in the body, CBD may also prevent heart disease by reducing cellular damage when we are exposed to free radical generators such as processed foods and environmental pollution.
CBD also slows down the reabsorption of a chemical called adenosine (meaning you have more adenosine in circulation), which inhibits inflammation and helps maintain healthy heart function.
If you are already taking medication for blood pressure, cholesterol or other heart conditions, it is important to consult your doctor before starting CBD. High doses of CBD may interfere with the metabolism of some of these drugs, which can have problematic consequences.
