Vapen can increase the risk of a heart attack or stroke because of the flavorings in e-cigarettes.
Scientists who have the flavored & # 39; e-liquids & # 39; those used in the devices tested, discovered that they damage the cells that line blood vessels, which could lead to cardiovascular disease.
Electronic cigarettes are much less of a health risk than conventional cigarettes because they do not contain tobacco that causes lung cancer.
However, they contain nicotine, which can narrow and harden the arteries, and often taste to make the vapor they produce more attractive.
Scientists from Stanford University who developed the flavored & # 39; e-liquids & # 39; tests that were used in the devices, discovered that they damage the cells that line blood vessels, which could lead to cardiovascular disease
Researchers at Stanford University tested six flavors, including fruit, tobacco flavors, cinnamon and menthol, on the cells that line the blood vessels. They found the flavors, including different levels of nicotine, caused DNA damage, cell death and inflammation.
Experts believe that this damage to the cells that lead blood vessels causes them to harden and form clots, suggesting that intensive use of sheep can increase the risk of heart attack or stroke.
This shows that people who use e-cigarettes are more likely to have a heart attack or coronary heart disease.
Dr. Joseph Wu, who led the Stanford Cardiovascular Institute study, said: & We have had no data so far on how these e-fluids affect human endothelial cells.
& # 39; This study clearly shows that e-cigarettes are not a safe alternative to traditional cigarettes. When we exposed the cells to six different flavors of e-liquid with different levels of nicotine, we saw significant damage.
& # 39; The cells were less viable in culture and they began to show multiple symptoms of dysfunction. & # 39;
E-cigarettes have been used by around three million British adults in the decade or so they are available.
To see how they can affect arteries, researchers took cells from the blood of patients and & # 39; reprogrammed & # 39; they with chemicals in the lab in the cells that aligned blood vessels. This avoided painful surgery to remove the cells naturally.
The cells were exposed to e-liquids flavored with fruit, tobacco, sweet tobacco with caramel and vanilla, sweet butterscotch, cinnamon and menthol.
The results, published in the Journal of the American College of Cardiology, show that the cells have increased stress, inflammation and in some cases death. The worst effects were observed for the flavors cinnamon and menthol, even if they do not contain nicotine.
Experts believe that the flavors themselves may be toxic enough to cause damage to the blood vessels.
Dr. Wu said: & # 39; When you smoke a traditional cigarette, you have an idea of how many cigarettes you smoke. But e-cigarettes can be deceptive. It is much easier to expose yourself to a much higher nicotine level during a shorter period.
& # 39; And now we know that e-cigarettes probably also have other significant toxic effects on vascular function. It is important that e-cigarette users realize that these chemicals are circulating in their bodies and affecting their vascular health. & # 39;
